Tires: Tire Side Wall Cracks, khumo tires, wall cracks

Question
Hi - have a set of Khumo tires on my 2001 Mazda 626. They have about 25,000 miles on them but are about 3.5 years old. Tread looks good but noticing cracks developing in the sidewall. Is this reason for concern? Time to replace them? Thanks for the advice

Answer
Mike,

Cracking is a normal part of aging in rubber.  If the cracks are small and shallow, then there is little to worry about, but if they get extensive, then the tire is trying to tell you it needs to be replaced.  You need to have someone look at them to be able to tell the difference.
