Bad air quality while you’re driving around Williamsburg is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they’re fairly new on the scene, a lot of folks don’t know about them yet.
These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as thee microns. By contrast, a grain of sand is about 200 microns.
So your cabin air filer can clean out dust, pollution, pollen and spores, to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner’s manual, but they typically need to be replaced at around twelve to fifteen thousand miles.
The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so you’ll want to have your Corbin KY service center, Johnny Wheels, take care of replacing them.
As we said, many people don’t realize they have a cabin air filter and go to their shop complaining about a funky smell in the ventilation system. It turned out to be a cabin air filter that was long overdue for replacement – really dirty and starting to smell. A quick replacement and they were on their way and smelling fine.
People who are allergy sensitive can really benefit from a cabin air filter, as it keeps allergens to a minimum. If you’re one of them, you’ll want to stay on top of your filter replacement schedule.
Of course if you do a lot of driving in dusty or polluted conditions, you’ll need to change your cabin air filter more often.
We live in such a disposable society. It’s amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough – they had to do without. Most people couldn’t afford new cars very often, so they had to make them last as long as they could.
It’s a good thing that cars are more reliable these days. They just don’t break down as often. And the good news for us KY penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Corbin car owners making sure we follow the manufacturer’s recommended maintenance schedules.
Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some parts don’t get properly lubricated and they start to wear out faster. Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. Same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.
It is probably even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they are a bit more stressed anyway. But it is never too late to get back on track with your maintenance and to hold off further damage.
And it really does start with the oil change. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. It’s like your safety net. Go in for an oil change on time, and let your service advisor help you keep track of the rest.
Some things are going to wear out along the way, things like alternators, water pumps, etc. But fixing those at Johnny Wheels is cheaper than a new car payment. And taking care of problems early means they have less time to mess with other things. It is like having high cholesterol – you don’t want to wait for a heart attack before you address it.
So, when are your tires actually worn out? This is a question a lot of us in Corbin KY ask ourselves. For many, the answer is ‘when they no longer pass a safety inspection’. But waiting that long can have a serious impact on your safety.
The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Johnny Wheels (just call 606-528-8473) to find out what your requirements are in the Corbin KY area.
Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety?
Well, Consumer Reports issued a call to consider replacing tires when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the big issue is braking on wet surfaces.
We tend to think of the brakes doing all the stopping, but you also need to have effective tires to actually stop the car. When it’s wet or snowy in Corbin KY, the tread of the tire is critical to stopping power.
Picture this: you’re driving over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.
This is where the studies come in. We think you’ll be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to cover it.
A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested – this is the depth suggested by Consumer Reports
When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.
Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.
Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. Obviously this is really a big safety issue.
The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable, was the tires.
So, how do you know when your tires are at 4/32”? Well, it’s pretty easy. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.
Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.
Tires are a big ticket item and most people in Corbin KY want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out? For us, and we would guess for many, the answer is “no”.
Well, Mr. Washington, let’s go out and look at my tires.

The hottest Corbin news story may be different everyday, but there’s one topic that seems to come up over and over again – the price of gas in Corbin. But we’ve found several basic things that any Corbin vehicle owner can do to greatly reduce their gas consumption, save money, and help the Corbin, KY environment. You can really impact your fuel economy by how you drive – but first, here’s a review of things you can do for your car that’ll save gas no matter how you drive.
The first one is keeping your tires properly inflated. That can save two miles per gallon. Driving on low tires is like driving through sand – your car just has to work harder. Most Corbin service centers will fill up your tires for free, so just ask your service advisor. Also, make a habit of checking your tire pressure whenever you get gas in your car. Many Corbin gas stations have an air hose you can use for free.
Another important item is to keep your air filter clean. An air filter all clogged up with dirt and bugs doesn’t let enough clean air through to efficiently burn fuel. Using a dirty air filter will cost you almost two miles per gallon in reduced fuel efficiency. And worn spark plugs can cost another two. A spark plug can fire as many as 3,000,000 times for every thousand miles driven. Check the owner’s manual for replacement recommendations.
The biggest item is the oxygen sensor. This device provides the engine management computer with information it needs to fine-tune the fuel/air mix. When that’s messed up it can cost up to three miles per gallon. And of course, there’s dirty or substandard oil. Dirty oil causes extra drag. The wrong grade may be too thick. That’s another .4 miles per gallon right there.
One item Corbin residents seldom think about is their gas cap. A worn, loose or missing gas cap can cost another two miles per gallon. Adding up all of these worn, missing or sub-par items leads to a total of almost 11.4 miles per gallon in reduced fuel efficiency! And with current gas prices in the Corbin area, the cost really adds up. Taking care of these simple maintenance items will save big bucks at the pump.
Now most people aren’t missing on all of these items, but think about which ones might affect you right now! And don’t forget tune-ups, dragging brakes, low transmission fluid, fuel system cleaning, wheels out of alignment, PCV valve, fuel filter and other key services spelled out in your owners’ manual.
Johnny Wheels knows all this stuff and can tell you when you’re scheduled to take care of each item. Create a system of your own to track your service schedules, or just use the computer system at Johnny Wheels – which may also be updated with recall notices and maintenance schedule items from your manufacturer.
You know, at Johnny Wheels we get a lot of people asking about how to prepare their car for a trip. That’s a big deal. You could be driving through mountains and deserts in some pretty lonely areas outside of Corbin so you may be anxious to know that the car is up to the task and won’t leave you stranded.
You really do need to plan ahead for a major road trip – there are a lot of things to get ready. Where should you start? You could start with the tires. Look them over for tread wear and check to see that they are properly inflated. Take a quick test drive around Corbin to see if you can feel any vibrations: are the wheels are in balance? Is the car tracking straight? Is the alignment ok?
Come in and see us for trip inspection.
Johnny Wheels 1513 Cumberland Falls Highway Corbin, KY 40701 606-528-8473
The next thing is a full service oil change to make sure all of your fluids are topped off and you have fresh oil for the trip. And if your car has over 75,000 miles, you may consider putting in the high-mileage formulation to clean harmful sludge deposits in the engine. You may also need a new PCV valve and an engine air filter.
How about your transmission and brakes? Have you had your transmission and brakes inspected in the last six months?
How are your wiper blades? There’s nothing like not being able to get rid of the bug juice on a long road trip away from Corbin.
Check your owners’ manual for any other recommended service and have Johnny Wheels do the multi-point inspection before you head out.
Consider also having the coolant system serviced – you want to stay within the manufacturer’s recommendations. If you’re towing a trailer you’ll want to be keep in mind that you’ll be going a long way under severe conditions.
A lot of folks overlook severe conditions like towing, or summer heat, or driving on dirt roads. Plan ahead for your next road trip – we want you to get there and back.
Don’t you hate it when you hear that squeal from under the hood? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator-which charges the battery, the water pump-which cools the engine, the air conditioning and the power steering pump. All pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components.
Serpentine belts are especially tough. They can last for years and go for tens of thousands of miles. But, with time they wear out. If your belt breaks while you are driving, everything will come to a halt within minutes. You have to stop the car or it will overheat, potentially causing major engine damage. And it probably won’t be at a convenient time or place. You might even need to get your car towed to a Corbin, KY automotive service center. That is why manufacturers recommend a belt replacement on schedule. You really should get it done on schedule because a belt failure will definitely take you off the road.
If you hear a squeal when accelerating or a slow, slapping sound at idle, you should have your serpentine belt looked at. Your service technician will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks an inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.
Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled vehicle to a service center for repairs. An ounce of prevention is worth a pound of cure. To schedule a belt inspection, call Johnny Wheels at 606-528-8473. We are located in Corbin at 1513 Cumberland Falls Highway.
This is something really amazing: For every gallon of gas your Corbin car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.
That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.
Dusty conditions in and around Corbin or polluted city driving means you’ll need to change your filter more often. Your Johnny Wheels technician can check your filter for you. In fact, it’s often a routine part of an oil change.
When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.
Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.
So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.
Stop by Johnny Wheels at 1513 Cumberland Falls Highway, Corbin, KY 40701, and we’ll take a look at your air filter for you. Feel free to give us a call at 606-528-8473 to make an appointment.
Let’s talk about deciphering the auto service menu board. Corbin, KY service centers like Johnny Wheels have a board that lists the routine services they provide. But some people don’t know what these services really are unless they ask. Let’s go down a typical list, in alphabetical order, starting with air conditioning service.
Feel free at any time to give Johnny Wheels a call at 606-528-8473 to learn of the many services we offer, or stop by our Corbin, KY auto center at 1513 Cumberland Falls Highway 40701.
First remember that all of these services are recommended by vehicle manufacturers. They set how often or at how many miles the service should be done.
Air conditioning service involves purging the old refrigerant and capturing it for proper disposal. Then fresh refrigerant is installed. The fresh refrigerant will lubricate the system and will also help it cool better.
Alignment. Service centers like Johnny Wheels make sure all four wheels are lined up and track with each other. This reduces tire and suspension wear and improves safety and handling.
Battery service. Service centers like Johnny Wheels inspect the battery for corrosion, leaks or damage. Test the battery’s ability to hold a charge. If the battery’s still strong, clean it up. If not, replace it.
Brake service. This could be two things. A brake inspection to see if the brakes are working well mechanically and to see if the pads are still safe. If not, replace the pads and make any repairs that might be in order.
The other thing is to evacuate the brake fluid, clean out the system and replace it with fresh fluid. This is important, but often over looked.
Cabin air filter. The cabin air filter is the filter that cleans the air that comes into the passenger compartment. It works like the filter on your furnace at home. It gets dirty and needs to be changed often.
Cooling system. This is the cooling system for your engine. Replace the old coolant with fresh to protect your radiator and other cooling system components from corrosion.
Differential service. Every vehicle has at least one differential. They don’t require service very often, so people don’t think of them much. The differential transfers power from the drive train to your wheels. Drain the old fluid and add fresh lubricant.
Engine air filter. This filters the air that’s burned in the engine. It also gets dirty and needs to be replaced often.
Fuel filter. This filter cleans the fuel before it gets to the engine. Like the other filters, it too gets clogged and needs to be replaced in order to maintain good flow.

Most folks around Corbin have had a flat tire. You know it’s inconvenient and a pain. Our tires are important. Keeping them in good working order isn’t just a big safety issue – it also has a financial impact. With high gas prices, we’ve all heard about the importance of keeping proper tire pressure to save on gas. In addition, proper inflation promotes even tread wear so your tires last longer.
There’s another danger to under-inflated tires. Low tire pressure puts added stress on the structure of the tire itself, causing it to break down prematurely. Also, under-inflated tires generate more heat which also reduces tire life. So get those slow leaks fixed quickly – don’t just keep airing them up every few days. You want to avoid serious tire damage.
Tires can also be damaged by road hazards in and around Corbin. Punctures, cuts and impacts on curbs or potholes can also cause damage that could lead to tire failure. Sometimes, it’s something that a visual inspection would reveal. Take the opportunity to check your tires when you’re gassing up. Look for slashes, missing chunks, nails or screws in the tread or just uneven wear. Of course check the air pressure too.
Now tire damage can be on the inside where you can’t see it until it’s removed from the wheel. Such damage could come from a severe impact, driving on a flat or even just low pressure. Some punctures can cause internal damage that are too severe to be repaired. You may see our Johnny Wheels professionals take the time to remove your flat from the rim and inspect the inside before repairing it, which means we’re just following good procedure.
Now some tires just can’t be repaired. A puncture may be too large to plug. Also, the puncture could be in a location that’s not safe to repair like in the sidewall or outer portion of the tread. So called run-flat tires should not be repaired because their design is such that internal damage can’t be detected by a visual inspection.
It is also important that repairs should only be done by a qualified tire specialist like the ones we have at Johnny Wheels. You can buy self repair kits – save those for emergencies, like when you’re off-roading and need a quick fix so you can hobble back to civilization and get professional help. If you need to use a repair-in-a-can product, remember it’s a temporary measure only and your tire needs to be properly repaired as soon as possible.
Here are some other considerations: Repairing a flat may void your tire manufacturer’s warranty – just something to keep in mind. Also, if you repair a speed rated tire, you should not use it in any motorsports or operate it above legal speed limits. Your tire professional will repair your tire whenever it’s safe to do so and he’ll advise you when it’s better to replace it. So watch those curbs and keep the air – on the inside.

It seems like everywhere you go around Corbin, KY you see custom wheels. Big trucks, little cars, mini-vans – it doesn’t matter, people are expressing themselves with custom wheels. Some people want smaller tires and wheels – some want larger – and some want them enormous. So where do you start if you want new wheels? We suggest you start with your budget. We know, that sounds so practical. But if the look you’re after goes beyond just new tires and wheels and enters into the world of suspension modifications, you need to be prepared for the additional cost.
Let’s start with something easy – you want to give your ride a unique look and the stock wheel size is just right for you. One of the concerns you will have is that the new wheels have the same offset as your factory wheels.
First, what is offset? The wheel bolts onto the hub on the car’s axel. The distance from the inside edge of the wheel to the point at which it bolts on, is the offset. If the new wheel has a different offset from the factory, the tires may rub on the inside or outside of the wheel well. That could lead to catastrophic tire failure.
Your Corbin tire and wheel professional can help you find the right size wheel – or install adapters to make your new wheels fit. All you have to do is pick from the hundreds of styles available.
So, what if you want to upsize? Well, if it is just bigger wheels you want, but you want to keep the same overall tire diameter, that’s pretty easy. The same offset concerns apply. You need to know that the tires will likely be a little bit wider than the originals and could rub when you make sharp turns. A tire professional at Johnny Wheels can help you avoid this.
It is also important to keep the same overall tire diameter because changing the rolling diameter can mess with your anti-lock brakes and stability control systems. Are you starting to see why you want to consult with a tire and wheel expert? Is “super-size me” your motto? If it is, you are going to have to lift your vehicle to make room for those huge tires. A mild lift doesn’t require extensive modifications. An extreme lift means a lot of new hardware under the vehicle. It also means a lot of stock electronic systems need to be recalibrated to the new tire size. For example, your speedometer and odometer will give false readings if they aren’t recalibrated.
You should also be aware of possible performance issues. Bigger tires and wheels weigh more. Experts refer to this as unsprung weight because it isn’t held up by your suspension system. Increased unsprung weight affects performance in different ways than an equivalent amount of groceries or little soccer players in the passenger compartment. Acceleration is negatively affected. Stopping distances may also be increased – sometimes dramatically. If you want really big tires and wheels, you might need to upgrade your brakes to compensate.
Heading the other direction, some folks like to run smaller than standard wheels and lower the suspension. All of the same fitment issues still apply as well as calibration issues. Don’t think that suspension modifications are a bad thing. Many systems actually improve ride, function and performance over the stock set-up.
Regardless of your budget, you want your vehicle to continue to do all the things you need it to do. Some of those show cars and trucks you see on TV look fantastic, but have been modified in ways that may not suit your needs. For example, if you put large rims on your SUV with low profile tires, you may be in for busted rims if you go off-roading a lot. There just isn’t enough sidewall to absorb the impact of thumping over rocks.
Some people stuff the largest tires and wheels possible in their vehicles but have to severely restrict suspension travel so that the tires aren’t rubbing all day. That can lead to a very harsh ride. Again, talk with your Corbin wheel professional about all of these things: how you drive, what look you are going for, your budget and what compromises you are willing to make.
At the end of the day, you’re going to be rollin’ out of there with one sweet ride.
