As I recently mentioned, I got to listen to Roger Marbles for and hour and then have another half hour of impromptu discussion outside the door. As said, I have not yet digested everything I learned, but we are getting closer.
I am writing today to forward this link:
http://www.rvtiresafety.com/2014/08/how-do-i-inspect-my-tires.html
A portion of what I wanted to pass along is there. But there were two things that hit me with the importance.
First is: If you have run a tire low on design pressure for the load, that tire has been damaged.
Reinflating it will not correct the damage. Ego, checking tire pressures is more important than most of us realize.
The second is that heat is worst the enemy of tires. There usually seven layers (often more) of different rubber compounds in a tire. Heat can cause them to loose the bond that they are supposed to have with each other. He did specifically point out that a class B near the door had white tire covers and mentioned that it was the right thing to do. Someone asked about ozone damage. Roger replied that this was a non-issue as tire companies all use ozone damage resistant compounds in the outer layers to prevent this damage.
I asked him specifically about the seven year life issue, to this he replied with a very firm Maybe. He went on to say that (again) the big issue was heat and if he knew the thermal history of a tire he could predict its useful life very accurately. He would not answer if there was a definitive age.
If you want to learn a whole lot more without me getting around to writing it (and even that is a crap shoot), go to Rogers's website/tire blog.
http://www.rvtiresafety.com/ and you will find answers to questions you haven't even thought of yet.
