What Do Tire Numbers Mean?

When you’ve looked at your tires or shopped for new ones in Mansfield, you’ve probably seen a code on the tire’s sidewall. Ever wondered, “What do tire numbers mean?” Those numbers and letters are like a secret language that tells you the tire’s size, type, and what it’s good at. Whether you’re tire shopping or just curious, let Buckeye Chrysler Dodge Jeep RAM FIAT Superstore help you crack the tire number meaning.

What Do the Numbers on Tires Mean

To truly understand your tire number meaning, breaking down that mysterious alphanumeric code is vital. Let’s take a closer look at each part and answer the question: What do the 

numbers on tires mean?

Example: P215/65R15 95H

While it may seem like gibberish, each section of code represents a piece of information to correctly identify the type of tire it is.

Decoding “P”

The starting letter “P” means it’s a “P-Metric tire” for passenger vehicles. “LT” designates “light truck” tires, ideal for lightweight pickups, while no letter prefix suggests a Euro-Metric tire with unique load capacities.

Decoding “215”

Next comes “215,” telling you the tire’s width in millimeters, measured sidewall to sidewall. In our example, it’s 215 millimeters wide.

Decoding “65”

After the slash, you’ll spot “65,” which is the aspect ratio. This figure shows the tire’s cross-sectional height as a percentage of its width. A 65% ratio means the height is 65% of the width, leading to taller sidewalls for larger ratios.

Decoding “R”

The “R” signifies radial construction, the most common type.

Decoding “15”

“15” indicates the wheel size, specifying the wheel diameter in inches. It tells us this tire is meant for a 15-inch wheel.

Decoding “95H”

Lastly, “95H” at the end reveals the load index and speed rating. “95” is the load index, indicating the maximum weight the tire can handle when properly inflated, usually ranging from 75 to 105 for passenger vehicles. The letter “H” represents the speed rating, determining the tire’s safe max speed based on its load capacity. Different letters signify various speeds, with “H” indicating up to 130 mph.

How to Check Tire Pressure

Taking care of your tires in Bucyrus or Ashland is a big deal. It’s all about making sure they’re happy and healthy for the long haul. Here’s how:

• TPMS Alert: Many modern vehicles have a handy Tire Pressure Monitoring System (TPMS). It’s like your tire’s best friend, letting you know if they need a little more air or if they’re feeling too puffed up.
• Easy Fixes: If your tires do need some attention, don’t fret. You can swing by a nearby gas station for a quick pressure boost. Or, if it’s easier, just drop by our place during your regular service visit. We’ve got it covered!
