Tread depth and tire life
Can anyone explain why all-terrain tires with deep treads don't last
significantly longer than car tires with relatively shallow treads? By the time my A/T tires are getting old, they still have more apparent tread depth than some new street tires. Is wear mostly about the hardness of the rubber compound, i.e. thicker treads made from softer rubber? Jim |

Goodyear provides one tire compound for the right side and one tire compound for the left side at each NASCAR Nextel Cup race. Mounting the usually-softer left side tires on the right side of the car will result in a severe fine. |
