Drivers like to know about the basics of their vehicle. Therefore, one of the more common questions we get at the Ray Price Chrysler Dodge Jeep Ram Service Center is, what do the numbers on a tire mean?

Well, that's a very smart question to ask-and we have the answer for you! The seemingly random numbers and letters on your vehicle's tires all have a specific meaning. To help you understand what they mean, we'll decipher the tire code for you. That way, you can know what kind of tires to equip your vehicle with for your drives around the Mount Pocono, Tobyhanna, Scranton, Stroudsburg, and East Stroudsburg areas.

Understanding the Tire Type

When you look on the side of your tire and see the mix of letters and numbers, you want to take it one step at a time. The very first bit of information to know is the tire type, which comes from the letter that starts the entire code.

Oftentimes, you'll see the letter P, which essentially means the tire was made for passenger vehicles. Other times, you might see the letters LT, which would indicate a tire made for light trucks.

Determining the Tire Width

The next three numbers that follow the tire type relate to the width of the tire from one sidewall to the other. The tire width is measured in millimeters. Therefore, if the number is 265, your tire has a width of 265 millimeters.

The width of your tires will vary depending on the type of model that you have. Changing the width as well as other proportions of the tire can affect the grip, the ability to travel on off-road terrain, fuel efficiency, turning radius, and other aspects of your car's performance.

Next Up? The Aspect Ratio

The aspect ratio is the number that follows the slash that separates the first few figures of the sequence and the next grouping of letters and numbers.

Essentially, the aspect ratio is the height of the tire relative to the width. If you were to look at your tires and see a 55 after the slash, then that means the tire height is 55% of the tire width.

Construction of the Tire

The tire construction is how the layers or treads of the tire move. Construction is indicated with a letter. For instance, R is a common letter used for this measurement, which means that the tires are constructed with a radial design.

Judging the Wheel Diameter

Then, we come to the next two numbers, which can range anywhere from 14 to 22 and even beyond depending on your model type. These numbers indicate the wheel size, or the diameter of the wheel, that the tire is intended for. The size is measured in inches.

Speed Rating

Finally, you'll come to the last cluster of letters and numbers, which may look something like 95H. These figures relate to the speed rating, giving you an idea of how fast any tire should reasonably be pushed.

The numbers on your tires are just one aspect of a vehicle that is good to know about when you're traveling around Mount Pocono, Tobyhanna, Scranton, Stroudsburg, and East Stroudsburg.
