Also if anyone has the roll-out or true diameter of a set of 285/ 75 R16 BFG AT's also interested ine the 305/70 R16 in the same tire. Last but not least possibly the 325/60 R18 in the pro comp x-terrain or any tire of that size?http://www.dieselplace.com/forum/smileys/Confused.gif


The true diameter can be found by marking your tire with a piece of tape. Start with the tape at the very bottom on the tire and mark it on the groud where you started. Roll forward letting the tire make 2 revolutions with the tape stopping again at the very bottom. Then mark you spot and measure the distance between the 2 points.


If anyone could please help me out on ANY of this ASAP would be a great help.http://www.dieselplace.com/forum/smileys/Big Smile.gif

I don't know the actual. Go to the BFGoodrich website to get a close estimate. They have a chart IIRChttp://www.dieselplace.com/forum/smileys/Ermm.gif Get the tire heigth (285's are I think 32.8) and multiply by pie.Edited by: dmaxfan

We have the MBRP Duals with free tips for that price. I don't know if it was us or not though. Let me know if I can help.

the problem is that the tires dont roll out to what they are said to be. the tires on my truck right now rolled out on the test to 187in but if you find the diameter of the tire muliplty it by pie and multiply that by 2(for 2 revolutions) it comes out to 196in. wouldnt be so bad if i had decided on what tires i wanted to run.
