Tire Replacement intervals???

You have been very lucky If you have a 10y/o tire with max pressure and haven’t had a problem.

This topic has been discussed alot. I run my tires until they wear out or until the physical condition of the tire tells me to replace it.
Never had a blowout. Over 50 years of driving. 20 years class A RVing.
I don't expect to change things.

You're right, it has. And it will keep coming up, over and over, and each time it does, everyone will expound on how and why (sometimes) they do things as they do, and no one will change their mind based on any of it. It's a waste of time, really, is what it amounts to.

The blowout resulted in repairs costing over $7K and several months downtime, and these were name brand, major market tires, not some Asian-knockoffs. I learned a hard lesson from that experience, one that taught me that trying to extend the life of RV tires to "10 years", or some such fantasy time period, is false economy at best, and any advice to try to keep them in service that long is inviting expensive trouble.

YOU run them 10 years. I run them 5 - not a day more. YMMV

And good luck with that.

The 10 year figure is the max age for RV use. A closer read of mypost should make it clear that there are many reasons to replace sooner than 10 years but no matter what they look like they should be replaced after 10 years of service.

Was your "Blowout" a sidewall run low flex failure or was it a belt separation as covered in THIS post?

Didn't your TPMS provide a warning of your "Blowout"? Why not?
Checking the air in a campground each morning tells you nothing about the pressure 10 or 100 miles down the road. It is relatively easy to fail a tire in just a few miles. A TPMS is much like an engine oil pressure or water temperature gauge. You could check the oil and water each morning and do away with the dash gauges too but I would not want to do that.

70 mph is a bit fast for a large Class-A, especially since there is a clear stated 75 mph max for RV application.
Just because you can doesn'tmean you should.

Anyway gald to hear you are OK.
