Re: How much longer will my front tires last?
Cracking is not a sign of wear (how many miles it has), it has more to do with tire material and environmental conditions. Check out the 4 digit code on the sidewall to determine when the tire was manufactured. If this occurred on a tire less than a year old, I would be emailing the tire manufacturer. With that said, cracking is not really dangerous if it is superficial. If it goes in deep, which is kind of subjective, then I would be worried.
