Tires and wheels...2004 Suburban

[njsteve]

I always rotate my Geolanders at every oil change (5000 miles) and get excellent wear across the tread. No cupping whatsoever.

You want load capacity if you are pulling a trailer. You can't have too much sidewall strength. I remember back when my truck was new and the local tire store recommended and installed a set of Michellins that were load range C instead of E on my Suburban. He said they would be fine and give a better ride too.

Yeah... a much better ride because they turned to mush in under 10,000 miles. When I dismounted them to replace them with a load range E tire, I stood the dismounted tire up vertically and it flattened completely to the ground like it was a deflated inner tube. There was no sidewall strength whatsoever remaining.

Here's the ply/load rating chart:

Plies#
4 "B" 35 psi
6 "C" 50 psi
8 "D" 65 psi
10 "E" 80 psi
12 "F" 95 psi
