Are dry rotted tires a time bomb?

I have 2 Michelin XZA3 on my steers that are dry rotted. They are fairly new with plenty of tread left but have been sitting on a truck that only ran once in a while (10k miles a year). They re 16ply and was wondering if I could throw them on the drive axle and maybe get some more miles out of them or should be happy they haven't blown yet.

I know now that the sun will kill $500 tires real quick and to cover them when sitting!

Thanks

YES, they are a time bomb. It's the biggest issue in the RV world, the tires dry rot long before they wear out and you can never convince the RVer's to replace them.

While I'm no expert on tires I would take them to an expert and let them physically look at them. Hard to give advice on something of this nature without actually seeing the tires. But I would get them off the steer axle PDQ

If they are dry-rotted enough to the point of visible cracks in the sidewall, a tire man would be crazy to air them up again after moving them to the drives. You should get rid of them and take your loss, learn the lesson and go on with life.

I would like to see a picture if you could post one.

I recently put my trailer on the road after it sat for 4 years 9 months. My tires didn't appear to be dry rotted so I just ran them. I felt uneasy about them and wanted to change them out when I had a chance.

I ran them for a little over 4 months and never had a problem. I don't haul heavy weights (30,000 and under).

I had an opportunity to make the switch to wide singles so I did that. The tire shop gave me $100 per tire so they didn't think they were bad either.

I also want to add that my trailer sat in Dallas, TX for that time period and it was very hot.

Our local fire department removes the tires when the date of manufacture exceeds about 7 years of age. Nothing like a blown tire running at high speed going to a fire carrying a full load of water and crew. We look up the expected life of the tire and replace them on schedule. Farmers wait in line to buy the takeoffs. Tires are still in good condition. We just don't need or want any liability issues.

My truck sat for 4.5 years and the drive tires (China) rotted. Within 20K miles of it back on the road, 3 out of 8 blew. I replaced all 8 and sold the 5 to a local ranch for $25 a piece. There they will rot more on their hay wagons that see about 600 miles a year. However without much weight on them, and traveling 10 miles at a time, rarely exceeding 60 mph, they should be cost effective for the ranch.

I had much the same experience with China tires. They looked good on the outside but the inside liner was cracked and checked beyond belief. They could have blown just adding air or hitting them with the lug wrench or even jacking up the truck. An old tire should be treated like a bomb! Deflate them before doing anything. And destroy them so nobody can be hurt by them!
