RV'ers with No Goodyear G670 Problems

A retired tire engineer indicated to me that the principal cause of rivering was inflation. He said "Too many people inflate for the ride rather than for the load." He then added that the next biggest cause were shocks that were not up to the job. He also said that of course you will never convince the consumer of this, because they know it all. I might add that he never worked for GY.

I think this is all quite funny, as I sold tires for way toooo many years, and the consumer has not changed. One could never convince a consumer that the abnormal wear pattern was caused by their lack of maintenance, it was always the manufacturers fault.

How does your retired tire engineer explain that when an owner has his coach 4 wheel weighed, and adjusts the tire pressure to the manufacturers supplied inflation pressure tables, and has the suspension checked numerous times still has problems with rivering? Then this same owner puts brand M tires on, and all his problems suddenly disappear. Additionally, why do all the higher end coaches seem to come with brand M tires already installed? According to Spartan, their cost difference is approximately $100 per tire when supplying brand M instead of brand G. Over the 3 years of dealing with Goodyear issues, I easily wasted more than the $800 difference! Lastly, it was Spartan that recommended the switch to Michelins.
