I have them on my 2002 2500 Suburban in 285/75/16. I have had them since October 2008. I have had the old style MTRs and old style BFG MTs several times (182k on the truck). Therse are load range E, the others were load range D. I drive on the beach, in the snow of West Virginia, and the mud/rocks of George Washington National Forest. My sense is that the Firestones have a harder compound than the MTRs or BFGs. I do not really like these tires. I am getting better mileage out of them (I rotate every oil change). They are fine on rocks and have done well in what little mud I have put them in. I have not liked their snow performance - they are very slippery and I have gotten stuck several times with them in ways I never did with the MTRs or the BFGs. I will not buy them again. They are inexpensive and long wearing, just do not have the all-around performance I am used to. This is the best picture I have of the tires on my truck.
78Bronco: I have a different understanding of the Ford/Firestone problem as a family member works for Firestone. I'm sure there are folks out there who refuse to buy a Ford for the same reasons.
Why do you feel studs in a MT are "useless?"
That debacle aside, Firestone is supposed to be a leader in R&D.
