I have run the Michelin LTX (Load Range E) tires on my '99 K2500 Suburban since it hit 44,000 miles and the OEM Firestone tires needed to be replaced. I just replaced that set after more than 88,000 miles. I now have a little over 4,000 miles on my second set and am just as satisfied as I was with the first. The ride has been absolutely fantastic (quiet and smooth), but directional stability was a problem before I learned that the Michelins are very sensitive to the vehicle's alignment - - have added twice-yearly alignments to my regular maintenance and have had no return of the directional stability issues that I noted upon my intial switch to Michelins.
I run 70 psi as my usual inflation pressue, and have the tires rotated with every-other oil change (my oil change interval is 3,000 miles).
Good luck with your research!
