Which tires are best for me?

I'm in Central PA and I have a fullsize truck. I'm not concerned with road noise. These tires aree for my daily driver I take off road on weekends. I want a 37" mud terrain tire that lasts a long time. I don't want toyo m/t. I considered Cooper stt, BFG km2, TSL radials, and nitto mud grapplers. All opinions accepted

Dodge sucks!!!!!!

I dont know about the coopers or the new bfgs but I can tell you that the tsls and grapplers will where out fast(15-20k)Bfgs used to last a long time(harder rubber then the others)but I dont have any idea about the new mts.

New 2002 f150,fx4,5.4v8,after market tranny coolers and unirol tires.

the km2's are pretty good tire, not quite sure how long they last though.  but i know the bfg m/t t/a km  the original mud tire.  my father in law has been running them for two years now and he drives everyother week to the rigs from central wyoming to central colorado, so he puts on a lot of miles on those things and he couldnt be more impressed, and tho dont got that much road noise.  They work great in snow and mud and sand and almost anything you can think of.  and lots of other people that run this tread or similar treads (pro comp makes one very similar too) are very satisfied.  so if bfg dont got your size maybe procomp will, or the other way around.
