Tires – Understanding Size Markings

What Every Driver Needs to Know About Their Vehicle’s Tires

When it comes to vehicle maintenance, few things are as crucial as your tires. At Japanese Auto Repair, serving Suwanee and Buford, we know that understanding your tire size markings can make a significant difference in vehicle performance and safety. Let’s break down the markings found on your tires and explore how this knowledge can help keep you safe on the road.

The Anatomy of Tire Size Markings

Your tire’s sidewall is more than just black rubber—it’s a library of information. A typical tire marking might look something like this: P215/65R15 95H. But what does it mean?

Breaking It Down:

1. P: This letter denotes the type of tire. “P” stands for passenger vehicle. You might also see “LT” for light truck.
2. 215: This is the tire’s width in millimeters, measured from sidewall to sidewall. It’s crucial for maintaining stability and handling.
3. 65: This is the aspect ratio, a percentage that compares the tire’s height to its width. A lower number generally indicates a sportier tire with better handling.
4. R: Refers to radial construction, the most common type of tire design. Nearly all modern tires are radials, which offer better road contact, traction, and handling.
5. 15: The diameter of the wheel, in inches, that the tire is designed to fit. Correct diameter ensures proper fit and performance.
6. 95H: The number indicates the load index (how much weight the tire can support), while the letter represents the speed rating, showing the maximum speed the tire can handle.

Why Tire Size Matters

Performance and Safety:

• Optimal Handling: Correct tire sizing affects handling, braking, and overall driving comfort.
• Efficiency: The appropriate tire size is crucial for fuel efficiency. Incorrect sizing can lead to increased fuel consumption.
• Longevity: Properly sized tires ensure even wear, extending the life of your tires and saving you money in the long run.
