The Penny Test

In order for your tires to maintain traction with the road, especially during wet conditions, it is crucial that your tires have enough tread. The tread is the rubber grooves that surround the circumference of the tire, and it wears down with time. Typically a tread depth of 4/32″ or deeper is good to go. 3/32″ means you should replace your tires soon, and anything less than 2/32″ is considered a ‘bald’ tire and should be replaced.

Because you probably can’t eyeball those measurements or use a ruler, this nifty little trick comes in handy: the penny test.

  1. Grab a penny and insert it into the tread so that Lincoln’s head points down.
  2. Evaluate how much of his head is showing.
  3. If you can see his entire head, you should run over to Plains Tire and get the tires replaced.

You may find that some areas of your tire fail the penny test, while others are deeper and pass the test. If any part of the tire is less than 2/32″, you should replace the tire. Don’t put off doing this task, as it could save you from being in an accident. Plains Tire makes replacing tires easy. Come visit us at any of our nine locations throughout Wyoming!

How to Check Your Vehicle’s Oil

oil change wyomingOne of the essentials of car maintenance is checking the oil in a vehicle. This is a very basic task that everyone should be able to do. It’s quite simple, and all drivers both young and old can quickly learn how.

The oil plays an important role in keeping your car’s engine running smoothly. If you fail to keep the oil level/quality where it needs to be, you’ll experience some serious problems with the engine. So, here’s how to check your oil (which should be done at least once a month):

Open the hood, remove the dipstick, and clean it with a rag

The exact location of the dipstick depends on the type of engine, but you can look for a circular handle (usually yellow). Pull the handle to remove the dipstick. Get a rag to clean off the end of the stick so that it is clean of any oil. Then insert the dipstick back into the tube and push it all the way in.

Once again, pull out the dipstick and check the oil level

The dipstick will have some type of markings on the end. You might see the words Min/Max, Full/Add, two holes, or there may just be a section of the dipstick that has a cross-hatched pattern. Whatever the markings, check to see if the oil is below the minimum mark indicated on the dipstick. If so, that means the oil in your engine is low and more is needed. Find a cap labeled “Oil Cap”, or something along those lines, and add the oil there, NOT into the dipstick tube.

Now that you have checked the level of the oil, you will want to check the oil’s quality. Not only do you need enough oil, but you need clean oil. Look at the oil’s color. Is it light-colored or milky? If so, you should take it to one of the nine Plains Tire locations to have it checked. It’s possible that the coolant is leaking into the oil. Also pay attention to how the oil smells – if it smells like gasoline it is probably time for a change. To finish, rub some oil between your fingers. If it leaves a dirty smudge it’s also time for a change.

Congratulations, you did it!

With a little bit of practice, you’ll be able to finish this whole process in under a minute in no time! When adding oil, refer to the vehicle owner’s manual to make sure you use the right type of oil. For oil that needs to be changed, bring your vehicle to Plains Tire, located throughout Wyoming for our state of the art oil change services. We’ll have you in, out, and safely back on the road!

Fixing a Broken AC

air conditioning repairSummer will be here before we know it! We’re excited as you are. As you start getting ready for all those summer picnics, pool parties, and road trips with the family, we hope that you don’t forget to get your car ready for the summer too. One of the common summer-time flaws that people will encounter with their cars is an air conditioning unit that doesn’t work. Driving in the heat of the summer with no AC can be pretty miserable, so if this happens to you, you’ll want to know how to diagnose the problem.

There are 2 common symptoms when it comes to the AC illnesses. We’ll talk about how you can identify the problem and get it taken care of.

Symptom #1: Little or No Air Coming Out

If no air is coming out (not even hot air), then one of the major components of the AC has probably gone out. The vehicle’s AC system is comprised of a compressor, condenser, evaporator, expansion valve and a tube/fan system. All of these components are important, and if any of them fails for any reason, the air will stop flowing from your vents. Newer cars have a safety mechanism that shuts down a component if their is a refrigerant leak detected. Check underneath the car for oil stains, which hint that their is likely a leak somewhere.

Symptom #2: Only Warm Air Comes Out

Nobody’s car immediately blows cold air after sitting in a hot parking lot for a few hours, but if it continues to blow nothing but hot air miles into your drive, then you know something is wrong. This symptom is shared by a few different AC-problems, and knowing how to treat it may require help from the technicians over at Plains Tire. It could be something simple, like recharging the AC unit, or something more serious such as a freon leak.

Whatever AC problems you have, you can rest assured that the certified technicians at any of our 9 Plains Tire locations will take care of the problem at the best value in all of Wyoming!

Closer Look at the Air Filter

You don’t have to be a mechanic to have a basic idea of what an air filter is. Its name hints at what it does, but let’s take a closer look at this important part of your vehicle.

What is an air filter? What does it actually do?

What is it?

In order to achieve maximum performance, an air filter is an essential component of your car engine. It keeps all of those undesirable contaminants and particles out of the combustion chambers.

What does it do?

Your vehicle sucks air into the engine to be able to combust and create movement. The air passes through the vehicle’s air box where the air filter sits. The air then goes through the filter’s pleated material.

This filtration keeps the engine clean and running smoothly. Unfortunately, when the filter get clogged up, proper air flow is unable to enter the engine and the performance decreases.

Get this: A clean air filter can increase your acceleration up to 11%!

Should I replace it?

So, if you don’t know whether your filter needs to be replaced or not, ask a certified mechanic. However, there are ways you can know it is time. Pay attention to these signs and symptoms: a decrease in acceleration, a rough engine start, or a check engine light, all of which are signs that you should take your vehicle in for a check-up.

It is typically recommended that you replace your air filter every 15,000-30,000 miles. But, if you drive on a lot of dirt roads, you’ll probably want to replace it on the more frequent side.

If a clogged filter isn’t replaced when it should be, you’re engine will have to work that much harder and its lifespan will decrease. Sometimes filters can get so clogged that they finally tear, letting in contaminants into the engine itself, causing irreparable damage.

Who should replace it?

Here at Plains Tire, you can be confident that you are receiving the best care possible. We have years of experience, and our professional staff will treat you in an honest and friendly manner. For all of your vehicle maintenance needs, come on in to your nearest Plains Tire!

Is It Time For A Tire Alignment?

tire alignmentTo put it simply, tire alignment is whether or not your tires are pointing in the right direction. That said, the easiest way to know whether your tires need to be aligned is if your vehicle pulls to the right or to the left.

A number of different things can cause your tires to become unaligned, but the most common are running over a big pothole or hitting hard into the curb.

Not only is it a pain to have to try and drive straight when your vehicle wants to veer off to the side, it is also bad for the tires. Having your tires aligned will help to preserve the life of your tires, which will wear down very quickly if they are not properly aligned.

It’s possible that your car will appear to be driving straight, but you may still need your tires aligned. Special equipment is used to align the tires to the exactness of a fraction of an inch. The human eye probably can’t detect when the tires are out of alignment. A general rule of thumb should be to have your tires aligned at least once a year.

When you bring your vehicle into Plains Tire for an alignment, we will set the camber (inward or outward tilt of the wheels when looking head on), the caster (wheel tilt front or back looking from the side), and the toe (looking down at the wheels from above). We will also set the tire pressure to the manufacturer’s specifications. And with our 6-month/6,000 mile guarantee, you will know that you are getting the best value possible.

Snow/Winter Tires Vs. All Weather Tires

As winter begins it is important to understand which variety of tire will keep you and your loved ones safe. The first thing to consider is what the region is like where you live:

If where you live sees occasional flurries of snow and ice on the roads is rare, then an all weather tire will be your answer. If you deal with excessive snow all winter long, and constant ice and slush on your roads, choose a winter/snow tire. Here are some of the reasons why, and facts of each:

All Season Tires:

  • Tread on all season tires has less depth and aggressive features
  • This tread provides more comfort and a quieter driving experience, but grip will suffer in snow and ice
  • Tires will last longer in year round use and the ware will be more evenly distributed
  • All season tires offer a low rolling resistance, so they can produce a higher fuel efficiency
  • A harder rubber is used in all season tires, so it can adapt to all temperatures, but in icy conditions it can harden and reduce handling

Winter Tires:

  • Aggressive tread is especially designed to block snow build up and add traction in stormy weather
  • Rubber stays malleable against cold asphalt to maintain handling and control
  • Tread is engineered with snow and ice with a better biting edge for wet and snow covered roads
  • Winter tires provide the driver more control and confidence in potentially dangerous situations
  • Stopping time is significantly improved compared to all season tires

It is important to note, that winter tires should not be used in the summer as the soft rubber designed for snow will wear very quickly and will not handle well in heat.

What’s the Difference Between a Regular and Synthetic Oil Change?

Plains Tire oil changeWhen you walk in to get your oil changed, you will be asked the question: Would you like synthetic or regular? You might be able to guess that synthetic oil is higher quality due to it’s higher price, but you may not know exactly why. In order to make a more informed decision, let’s break it down.

What is it?

Regular, or conventional, oil is derived from crude oil, and that is pretty much where the process ends. Synthetic oil, on the other hand, is regular oil that undergoes further modifications which remove more of the impurities that are found in the crude oil and improve its protective and lubricant properties.


Your car engine has many moving parts. In order to keep the parts moving fluidly, motor oil is used to create a slippery coating of lubrication. Synthetic oils have a greater ability to keep the parts slick, especially at higher temperatures. Better lubrication means less wear and tear on your engine, which could extend the life of the engine.


Another purpose of motor oil is to clean your engine of debris. Regular oil sometimes forms sludge which can be harmful for your engine. Synthetic oil, with its fewer impurities, is better able to work without forming sludge, also increasing the life of your engine.

Oil Changes

Any type of oil will eventually break down and become less effective. That is why you should regularly have your motor oil changed. The benefit of synthetic oil is that it can last as much as three times longer than regular oil before breaking down. So despite being more expensive, it will get you further down the road than conventional oil.

It is clear that synthetic oil is superior in many ways. That said, regular oil will get the job done and is a good option as well. The most important thing to remember when it comes to caring for your car is to follow the recommendations from your vehicle’s manufacturer.

Take the worry out of changing your oil and bring your car on over to the nearest Plains Tire. We will ensure that your vehicle has the oil it needs so that your engine will keep running smoothly! Schedule an appointment today! 

25 Essential Items for Every Car

auto body shop casper wyomingAs a driver, are you prepared for unexpected emergencies on the road? Be ready by knowing what’s in your trunk and where to find it in a time of need.

We’ve made it easy for you be compiling a list of the 25 items you need to have in your vehicle at all times. Simply conduct a quick inventory of what’s already in your vehicle, then add what items you’re missing.

We’ve organized these 25 essential items into three categories: Maintenance, Safety, and Convenience.


  1. Spare tire. Don’t put your spare tire in the back then forget about it. Check that it’s tread and air pressure are at safe levels and that the tire jack and tire iron are in place. Doing so will ensure that the tire is ready in your time of need. If you need a refresher, refer to our blog post about How to Change a Flat Tire.
  1. Vehicle owner’s manual. Keep it close by, preferably in the glove compartment. You never know when you’ll need it for a quick reference.
  1. Insurance, registration, and auto shop information. If you are involved in an accident you’ll need your vehicle registration and insurance card. You’ll also need the contact information for your auto repair shop and AAA if you’re a member. Keep these items together and know right where to find them. The glove box or center console are ideal.
  1. Jumper cables. It’s absolutely necessary to have jumper cables with you. You car’s battery could die at anytime, and you don’t want to be left stranded. You also may need to jump another person’s car using your jumper cables. Our next blog post will be a how-to guide titled “Learn How to Jump Start a Car,” so stayed tuned for those helpful tips!
  1. Tire inflator and sealant. If your tire has a hole or leak, these will temporarily clog it until you can make it to the shop for a repair.
  1. Tire pressure gauge. Make it a habit to regularly check the air in your tires and keep them filled to a safe level. Doing so provides several benefits including improved vehicle handling, better gas mileage, increased tire longevity, and of course, safety.


  1. Water. You can’t survive without water, so this should be the highest priority. Store several bottles to have on hand in case you’re stranded for a lengthy amount of time. If you drink any of the water, be sure to replenish your storage.
  1. Food supply. Keep a few nonperishable food items in your car like energy or protein bars, or MREs (Meals Ready to Eat). These meals require water for preparation, so accommodate that in your water storage.
  1. First aid kit. You can buy these pre packaged with everything you’ll need. But if you use something, be sure to replace it.
  1. Fire starter. There are several different options, so you can purchase what you like. Matches or a lighter are basic options that work well.
  1. Flashlight. Check the batteries regularly to make sure they’re charged.
  1. Communication device. Don’t just rely on cell phone service. You could be out of cell phone range or a power source in an emergency. Prepare with a solar powered radio or walkie talkie.
  1. Tools. Multi tools are handy and don’t take up much room. You could also include a small tool kit.
  1. Reflective gear. To prevent being hit at night by another car, have reflective vests and flares on hand.
  1. Map. A GPS signal may be unavailable in an emergency, so always have a paper map in the car. You may even need to find your destination on foot if your car isn’t drivable.
  1. Ice scraper. In ice and snow you’ll need an ice scraper to clear your windshield so you can see as you drive.
  1. Blanket. Mylar space blankets are designed to keep you warm in extreme cold. However, a regular blanket is better than no blanket at all.
  1. Seat belt cutter and window breaker. If you or others are trapped inside a vehicle, these will help you escape. Keep them near where passengers sit, like the center console or glove compartment.


  1. Mobile power supply. What do you do if your car loses power and you need to charge your cell phone or other device? A solar powered mobile power source could be your lifesaver!
  1. Cash. In certain situations you may not be able to use a credit or debit card. Keep some extra cash on hand just in case.
  1. Change of clothes. You may be outside in the mud, rain, or snow and need a dry, clean change of clothes.
  1. Towels. You may need a towel to clean up messes or to dry off. Stock up on either a bath towel or paper towels.
  1. Umbrella. Store an umbrella to keep you dry on a rainy day.
  1. Toilet paper. You never know when nature may call and you’ll have to take a bathroom break! You might even just have a stuffy nose. For whatever purpose, it’s always good to have toilet paper or tissues on hand.
  1. Paper and pen. Go the old fashioned way. You might need to write down important information, like someone’s insurance when you get into an accident. Paper and a pen is also good for doodling on long road trips!

This may seem like a lengthy list, but you probably have many of these items already in your home. When an emergency strikes, you’ll be glad you took the time to pack these 25 essential items!

How to Know When Your Brakes Need Maintenance

Brakbrake repair and maintenancees undergo wear and tear as they get older and will eventually have to be replaced. How fast they wear out depends on driving habits, the quality of the brake pads, and vehicle type – to name a few factors. Yearly brake system inspections are vital to ensuring your safety, but sometimes things happen between check-ups. Fortunately, there are occasional warning signs between check-ups that will tell you that your brakes need attention.

Keep in mind that it’s very important to replace your brakes before they get too far gone. Metal-to-metal braking without braking pads can lead to expensive fixes on your vehicle.

Here are some of the warning signs that tell you that your brakes need to be looked at:

  • Brake Light: the red brake light lights up on your vehicle’s dashboard.
  • ABS Light: The automated braking system light is constantly lit up on the dashboard.
  • Low Pedal: brake pedal gets very low before it actually starts engaging.
  • Hard Pedal: you have to push the pedal really hard to make it move so that the brakes can engage.
  • Grabbing: brakes grab almost too hard and fast at the slightest touch to the pedal.
  • Pulling: vehicle pulls to one side while braking.
  • Noise: screeching or grinding noises when applying brakes.
  • Vibration: brake pedal excessively vibrates, even under normal braking conditions.

If you experience any number of these issues, make sure to talk to a brake inspection professional ASAP. It’s always better to be safe than sorry, especially when it comes to your safety.

When you foresee problems, remember that Plains Tire offers complete brake system inspections and repairs for very affordable prices. Let us be your resource to diagnosing your brake problems.
