- The sidewall of all tires sold in the US will have scores for tread wear molded into the rubber. A new car tire may have a tread wear rating as low as 150, and good quality replacement tires may have a tread wear rating of 600 in some cases. You get what you pay for, generally speaking. However, these tread wear numbers can only be accurately compared within one manufacturer's model line.

When Should I Replace My Tires? Tires don't require tread designs or even much tread depth to deliver traction on dry roads.
