Tire life?

[moose52]

When I bought my modified it came with several sets of rims and tires but I have no way to tell the age of the tires. Between grinding and tire preps do tires ever get too old?

[usafracer]

Yes they can get old and crack. They also get hard. Buy a new tire and check it with a durometer and then check the ones you have.

Then grind the tires you have and buy track claw and soften them to the new tires
