Have you ever looked at the side of your vehicle's tires and wondered what all those numbers and letters mean? The information printed on the sidewall can tell you important details about the size, performance, and age of a tire. That's why Jeff Wyler Columbus Auto Mall is proud to help drivers in Canal Winchester and our surrounding communities become better informed about their vehicles.
How to Read Tire Sizes
Apart from the brand and model of tires, the largest set of numbers point to the size. For example, a tire size of 235/60R18 would correlate to a width of 235 millimeters, a sidewall aspect ratio of 60 percent, and a wheel diameter of 18 inches. If you're having our Service Center near Groveport fit new tires, we'll help you find the ideal set for your vehicle.
The "R" before the wheel size standard for radial-ply, which is the most common type of tire thanks to its resistance to heat and wear. Some tires feature a "B" that stands for bias-ply, designed for low-speed applications like off-roading or trailers.
Load Index and Speed Rating
Another set of letters and numbers you might find on the side of your tires is the load index and speed rating. These are crucial to ensure your vehicle remains safe as you cruise around Pickerington, as exceeding either value can reduce handling or cause a blowout. Load indexes are two- or three-digit numbers that have a matching weight, with an example of 85 for a tire that supports up to 1,135 pounds.
After the load rating is the speed rating, which indicates the maximum speed a tire can be used when properly inflated. Speed ratings range from L (75 mph) through Z (149 mph and greater). It's essential for drivers near Columbus and beyond to choose tires with a load index and speed rating that match the specifications of their vehicle, especially when towing trailers or taking treks down I-70.
Visit the service center at Jeff Wyler Columbus Auto Mall to have your tires inspected and replaced if needed. Our knowledgeable technicians can help you determine the right type and size tires for your specific make and model. Proper tires are essential for a smooth and safe ride around Lancaster and beyond.
UTQG Ratings
The last set of numbers on the tire sidewall is the Uniform Tire Quality Grading (UTQG) rating. These grades rate the treadwear, traction, and temperature resistance ratings, helping you optimize performance on your daily commutes near Lancaster. A higher treadwear number indicates a tire that will last longer, while traction grades include AA at the higher end and C at the lower end. Temperature grades include A, B, and C, with A being featured on most winter tires.
