Tim, Aware of the damage that can happen when tire tread separates, which is what happened to us. Insurance comprehensive took care of it. After showing the tires to a national RV tire expert, to our RV dealer, and to our local tire shop, all experts, I can agree that the condition of the tires was expected for the age of them and how we used them. Bottom line, it could've been prevented by us. We are taking a different approach this time, but again with the warranty provided by the tire shop and opinions on the tires by our RV dealership (well respected in this area) and the national RV tire expert, both DH and I are comfortable with what we have.
Interesting that Maxxis is highly regarded. Our last RV came with Maxxis. We bought it brand new and within 2 years, the tires were showing signs of aging and cracking on the sidewalls and those tires had been manufactured the same year as the TT. We had to replace them.
