315/75/16.... 315/75/17... 325/60/20 Not sure what route I am going. I am assuming most are running 16's or 17's. Basically 35 inch BFG AT's, I want to know exactly how tall they measure. I have researched them online at BFG's website and found their measurements to be unaccurate. I was sure someone had 315's on here.

when i measured mine on my old truck a long time ago they were 34.4. You will be hard pressed to find manufacturers that acutally make a true 35, 37, or 33. they are out there, just alot of mfg's dont make them a true size

I was trying to use a calculator to see what effect 35's would have on my wheel speed and rpms truck pulling. I am trying to figure out if I will have enough hp to pull 3.73's with 35's or drop to 4.10's to turn 35's. I ran a true 33 12.50 R16 trxus this last pull and spun out a 3900 rpms with 55 psi in the back and 25 in the front. Debating if I can turn 35 inch BFG's next year ......or 34 inch BFG's.:spit:
