Justin,
I sure don't want to say any more about tires, but! My neighbor has been
using load range D tires since he bought his '73 Canyon Lands in '73. He
runs about 50 PSI in his tires and uses the same logic shown here. What
can I say, he's had his GMC longer then I have. He loves the soft ride.
He thinks I'm nuts to run at 80 psi on my load range E tires. He also said
that
a tire engineer from Michelin told him to use this weight divided by
wheel logic to calculate tire pressure. He's also blown about 6 tires over
70,000 miles and doesn't think much of it. He's 80 years old and thinks
tires are supposed to blow out? Maybe they did frequently when he was
younger.

I was pretty sure you didn't really imply that we should use that type
of calculation to figure air pressure. I did want to report however,
that there are folks out there that do. And my neighbour is one of them.
Good thing is that he rarely drives the GMC any more and when he does
he only drives around town. I would imagine he rarely exceeds 35 MPH.

He's also one that says that you should not wear seat belts in a GMC. His
claim is that since the view is so good up front, that you would see any
accident situation far enough in advance that you would have time to
jump in the back of the coach and be safe! I'm not making this up!

Needless to say I don't ride much with him in his GMC.
