I think I may have just found a couple more options I might consider.
Falken WildPeak AT P265/60/18 (30.6x10.7)
Hankook Dynapro ATM 255/60/18 (30x10.2)
Hankook Dynapro ATM 265/60/18 (30.5x10.7)
Hankook Dynapro ATM 265/65/18 (31.5x10.7)
I don't think any of these should need trimming or torsion bar adjustment..........
Also, can anyone tell me what the biggest tire size that would fit in the spare swingate would be? Would any of the above sizes fit?
