I came across this excellent informational article while researching why my car needs H-rated (and more expensive) tires, particularly since the car has only 33,000 miles and already needs new tires! Appparently, because my car is a V-6 it is considered High Performance; the H tires are rated up to 130 mph. (Now, mind you, I wouldn't even dream of driving that fast!)
So, here's the skinny on the "code" on your sidewalls:

Wonder what all those letters and numbers on your tire's sidewall mean? This chart will set you straight. If you like your current tires, buy more of the same. A tire with a different rating but the same size and type may give you a smoother ride or better handling in bad weather. TIRE TALK Typical Tire Label: P185/60R 14 82H IN PLAIN ENGLISH P indicates passenger car tire. LT stands for light truck, and T for temporary (spare)..... Speed-rating letters indicate the maximum safe speed the tire is capable of carrying under ideal conditions, for an extended period of driving. You might not feel a difference between riding on T-rated tires and H-rated tires, but you'll save money on the former. Higher-performance tires have softer, grippier rubber with shorter tread life. They're not only more expensive up front, but need to be replaced more frequently. (click through for more....) |
Thanks for the information, I never knew that about my tires. Upon research of my own tires, I actually have two different codes on my back tires. I always get used tires for my back wheels since its cheaper. Unfortunately, I think its the reason that they are wearing unevenly.
