Neither of those choices.Why not look at a super swamper radials?Irok,SSR or TSL/SX .Just curious as to why you limited yourself to those 3,when you mentioned HARD rock use.Going to check some prices.......... :finger:
Edit:And if your talking aboot saving some loot,you'd be better off going S.S over the 3 you listed that i could see
Pro-comp 37" Xterrain $355
Pro-Comp Mud TA : Not available,that was the non metric size
GoodYear MTR: $215
Iroc Bias :$167 36" flavor
Iroc Rad $214 36" flav
37x14 Iroc Bias :$178
37x12.5 Rad iroc $223
SSR 37" $220
AND the MUTHA of all WHEELING TIRES
38" Thornbirds $237 .... :finger:
And these were all 4x4 mag adds,so am sure a vendor could score you better pricing or call up a few of the mag guys an make em price match each other,til you get a bottom dollar price on the meats..anywho,thats my 2 cents,and that 2 cents leans toward Super Swampers for your junk.. :finger:
