o Quiet.
o Lightweight to maintain VX spirited performance.
o Make the VX look mean & aggressive.
o Long Lasting.

o Will fit WITHOUT "lifting".
Based upon the above requirements; there is only two(2) tires that meet the criteria, they are:
GENERAL - Grabber AT2 in P275/65R18 (32" O.D./44 lbs) This tire is also pre-pinned for "studs" (if desired).
PRO-COMP - All Terrain in P285/60R18 (31.3" O.D./43 lbs) This tire is close in O.D. to your current tires.
The above two(2) tires are BFG A/T "clones", and you will absolutely love the tread patterns of both. Check-out the GENERAL's at www.TireRack.com and check-out the PRO-COMP's at www.4WheelParts.com and www.TruckAddOns.com
