Have you ever looked at the side of your tire and wondered what all those numbers mean? The information printed on your tire's sidewall is actually very important for selecting the right tires for your vehicle. If you live in the Louisville area, understanding tire specs is crucial for navigating various road conditions year-round.
Tire Size
The tire size is one of the key pieces of information on the sidewall. For example, a common tire size looks like this: P215/60R16. Here's how to decode it:
- P = Passenger tire (LT would indicate a Light Truck tire)
- 215 = Tire width in millimeters from sidewall to sidewall
- 60 = Aspect ratio (sidewall height as percentage of width)
- R = Radial construction
- 16 = Wheel diameter in inches
Drivers in Clarksville should make sure to select tires that match the size specifications for their particular vehicle make and model. Consult your owner's manual or the placard inside the driver's side door jamb for the recommended tire size.
Load Index and Speed Rating
Following the tire size, you'll see additional numbers and letters that indicate the load index and speed rating. The load index is a number that corresponds to the maximum weight a tire can support when properly inflated. Speed ratings range from L (75 mph) to Y (186 mph), with most passenger tires falling between S (112 mph) and H (130 mph). If you frequently drive on the highways around Elizabethtown, choosing tires with a higher speed rating may provide added performance and stability.
Treadwear, Traction and Temperature Grades
Many tire sidewalls also include a Uniform Tire Quality Grade (UTQG) designation with three digits and two letters, such as 400 AB. In this example, 400 is the treadwear grade, A is the traction grade, and B is the temperature resistance grade. For treadwear, a higher number indicates a longer-lasting tire. Traction and temperature receive grades of AA, A, B, or C, with AA being the highest grade. Frankfort drivers who plan to use their tires for longer should consider tires with higher UTQG grades.
