Have you ever looked closely at the sidewall of your vehicle's tires and wondered what all those numbers mean? As a driver in Spring Field, OH, it's important to understand the information provided on your tire sidewall. Let's break down the meaning of each number and help you decipher your tire specs.
Tire Size
The first number grouping on your tire's sidewall indicates the tire size. For example, a tire that reads "P215/65R15" has a width of 215 millimeters, an aspect ratio of 65 percent (sidewall height compared to width), and fits a wheel with a 15-inch diameter.
Load Index and Speed Rating
Following the tire size, you'll find the load index and speed rating. The load index is a two or three-digit number that corresponds to the maximum weight your tires can safely handle when properly inflated. The speed rating, meanwhile, indicated by a letter, tells you the maximum speed the tire can maintain over time. A tire with a load index of 95 and a speed rating of H can support 1,521 pounds and speeds up to 130 miles per hour. If you frequently drive on highways around Yellow Springs, OH, choosing tires with a higher speed rating may provide added peace of mind.
DOT Code and UTQG Ratings
The DOT code on your tire's sidewall indicates the tire's date of manufacture. The last four digits represent the week and year the tire was made. You'll also find Uniform Tire Quality Grade (UTQG) ratings for treadwear, traction, and temperature resistance. These ratings give you a relative comparison of the tire's expected performance in each category. When shopping for new tires in Fairborn, OH, consider the UTQG ratings that best fit your driving needs and conditions.
