I've never had a car where the tires got all that old before wearing down the tread, but my daughter the student puts far fewer miles on her car.

Her tires are 6 years old and still have decent tread depth, but she's being told that new ones may be in order just due to age of the rubber. They are quality Michelin tires, not an el cheapo special.

Any thoughts from those of you who know way more than I do about this sort of thing?

Thanks!
