TIRES for my 2001

[mmeyn]

Needing new tires and having trouble choosing what to go with. Its a 4x4 extended cab and the 265 it came with are worn out after 23000 miles and look a little small. Thinking of going with a 265/85 but cannot find any Load range E tires. I pull a 32ft choose neck and need somthing that isnt going to wear out too fast. I would like an all terrian but that seems even harder too come by. What is everyone running and how long are they lasting? Best place to get them??
