We have plowed this ground so many times Paul that we will get no where by
doing it again. Look close our front and rear suspension is like no othe on
the road.
Some people are going to believe what ever they want, contrary to a mountain
of evidence to prove the point that D rated tires should not be used on the
GMC motorhome. Guess the world just has a certain percentage of contrarians
that have to prove a point, that escapes me.
The D vs E rated tires for the GMC motorhome was analyzed in detail in the
June 1983 issue of Trailer life and the July issue of Motorhome.
In addition both General tire and Michelin accepted and verified the
results. What else do we need to know?????
Since you opened the can of worms again lets really beat it up and scare
people. I would be willing to bet that those netters that are still running
D rated tires are inflating them to 65# cold. If they are running E rated
tires they are inflating them to the same. How about everyone stating what
kind of tires they have either D or E and the pressure they are inflated to.
Please check them before you weigh in on the issue once again and please be
honest. I would like to prove a point, and this is not meant to embarrass
anyone. i am just concered for everyones safety. If you have never had this
12,000# missle blow a tire at 60MPH than you have never been scared.
Thanks for the cooperation in advance. We have to kill this dangerous myth
once and for all. We don't want to lose anyone this summer to something we
can correct.
