Tire Dry Rot or Not

1322 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.

Neal: I would say that the tires you have pictured, with all those cracks in the surface rubber, need to be replaced regardless of age or mileage or tread.

When water gets into the steel belts the latter will rust. Not long after the steel will rust through and the tire is now liable to have a blowout.
