Tire Dry Rot or Not

1318 Views 50 Replies 23 Participants Last post by  RonArt
One of our vehicles has Michelin Defender tires with close to 50K miles on them. The tires are 6 years and 3 months old. Tread is 5 - 6 32nds. Since the car will be around longer than the useful life of the current tires I figured I would just replace them now. I'm also curious if any of the photos show dry rot. Dry rot photos online typically show tires with far worse but figured I would share here for some feedback.

Two things effect the life of a tire, wear and age.
you forgot the most important factor, UV rays

Direct sunlight deteriorates rubber, a car that is always parked in a garage, tires will last longer, than a car always parked in direct sunlight,

Tire companies don't know where people will be parking, so they just give a general estimate of 6-8 years,

If your parking in a garage all the time, your tires can, and will last longer,
