Dry Rot: Worn out Tires in only 15,000 miles

Miles and tread wear are not the only reasons you need to change tires. Time can also cause dry rot in 5-6 years. If you don't drive much, your tires could still be worn out. This video shows what to watch for and some of the signs or dry rot including cracking along the circumference of the tires, increased road noise, and failure to hold tire pressure.

The problem tires shown in this video were not Cooper tires (I have had many Cooper tires over the years and have had great luck with them). The tires with dry rot were Yokohama Geo lander tires.

Thanks so much for sharing 💜

You are welcome.

Interesting video. I had a set of Cooper's on my truck, which I use for my job. They were rated for 60K miles, I ended up having them for over a year and a half of near-daily use. Ended up getting 107K out of them, which is pretty wild, I couldn't believe it. Regular rotation and balancing can really stretch a set out quite a ways, that's the only guess I have as to why mine lasted so long. I definitely got my money's worth.

Thanks Buttrabies. I should be clear, the problem tires were not the Cooper tires. I have had so many Cooper tires and have had great luck with them over the years. The tires that had the dry rot were Yokohama Geolander tires. I think I have gotten my money's worth out of the Cooper tires I have owned (for example, the Cooper Discoverer STT Pro... great tires).

Good advice! Belts and hoses seem to have come a long way with durability but tires are hit and miss. Perhaps UV rays, winter road salt or other chemicals found on the roadways make the difference.

Good idea Aaron. Thanks. I wonder if the road salt and road sprays could be part of the reason for the dry rot and tread separation.

I would be interested in the Tire Identification Number (TIN) stamped on the tire. It is after the 'DOT' symbol. Cooper has an article on their web site. A 'brand new' tire might have been sitting on a dealer's shelf for years. Each manufacturer has specific recommendations for replacement after time, regardless of treadwear. Cooper's website says Ten Years (⁉). I think 5-6 years is more common. If a tire older than that has to be kept in service (farm use) keep travel speed under say 45 MPH to avoid heat build-up and a tread separation disaster. thanks for the video!

I should be clear, the problem tires were not the Cooper tires. I have had so many Cooper tires and have had great luck with them over the years. The tires that had the dry rot were Yokohama Geolander tires. They are gone now so I can't look up the TIN. I did not even know about that so I learned something new. Thank you for that info. And thank you for watching and posting!

@@sdkweber Yes, I like my Coopers, as well! from your video @ 2:36 I see [NYN0816] on the Yokohamas. If correct, that is the eighth week of 2016. That would make them 7 years old. I would certainly be watching them at that point!

@@jamesalles139 Great info James and good job finding that code in the video. They were on the Jeep for about 6 years. Thank you.

WTH? Chinese tire?

[@sdkweber]

No, not Chinese. Yokohama tires are made in Japan. I read they are a reputable tire. Maybe not... but then again this could have happened with another brand too.

[@jamesalles139]

@@sdkweber yes, materials of construction matter.

People are dying and we are worried about tyres... sir sue the company and resolve the issue
