hey so i have P255/70Rx16 all-terrain OWL tires on 16" Y-Spoke silver-painted insetcast aluminum wheels on my stock 08 FX4 (stock tires and rims)
are these 30's? i dont understand the p255/70rx16 conversion factors to the easy 30s,31s,32s etc. also whats tires can i get under it with no lift of anykind?-i dont want rubbing at all. how well does a stock fx4 preform off road....(steep trails, mud, sand, and rocks.)

Your 255/70R16 = 30.1" x 10".


I had 265/75R16's when I was stock...with no rub...and on my stock rims. 265/75r16 = 31.6". Looked good....no rub.....and the tires looked big. I see you have an 08...might be a good idea to crank your bars and find some 2.5" stock ranger lift blocks. Yours on your truck now are like 1.25" blocks.

How does it wheel? idk.....did pretty good with the 265's. Trailriding, mud, sand...rocks it pretty much blows(too low of clearence)....did well for what it was.
