That way, you’ll realize that reading your tire size is as simple as doing some quick research.

Reading Your Tire Size!

Before we review the other important factors about changing your tires, let’s get down to the nitty gritty. The tire size of your vehicle can be broken up into a few, basic details.

The first thing you’ll see on your tires is the letter “P.” This signifies that your automobile is a passenger car. Next, you’ll notice three digits followed by a slash, which indicate the width of your tire measured in millimeters. The two numbers after the slash are your tires’ aspect ratio.

Moving along, you’ll see an “R” next, which indicates the radial layers that run along your tire. The next pair of numbers you’ll notice is your tire’s diameter.

This is important because it tells you the measurement of your tire in inches. To ensure that you’re choosing the right tires, check your owner’s manual or contact your local service center.

Tire Replacement Warning Signs

By knowing a few common warning signs that your tires are ready for a change, you can keep your vehicle performing at its best. Once you begin noticing symptoms of old tires, it’s time for you to start shopping for your replacement set.

  • Bulging: If you notice that your tires are beginning to bulge, you should consider getting a new set. When this begins to happen, it increases the amount of pressure on your tires, which can lead to cracks or a blowout.
  • Thinning Tread: Think of your tire’s tread as its cushioning and grip for the road. When the tread begins to wear down, you’ll have less traction during slippery situations. So, if you notice that your vehicle seems less stable, it’s time for new tires.
  • Vibrating: While you’re rocking out to your favorite tunes, your vehicle shouldn’t be doing the same. So, if you notice any unusual vibrations from your car, it could be that your tires are starting to age. Once you experience this, head over to your service center for a replacement.

The Importance of New Tires

It’s normal to need a tire replacement. However, there are a few simple measures you can take to ensure that your tires stay healthy for as long as possible. By avoiding abrupt or hard braking and watching out for potholes, you can help your tires wear evenly and last for much longer.
