The tires on my wife's SUV have plenty of tread left on them but I recently noticed they have developed small cracks in the tread.

Tires are 8 years old and have 24k miles on them.


Just did a little internet research and see that it is recommended to go no more than 6-10 years on passenger 'car' tires.


Hate to replace tires that appear to have a lot of life left in them but I also hate to worry.


Thinking just spend the money and buy a little peace of mind?
