Differential calc - ZR-1 Net Registry Forums

Interesting!

I measured my BFG G-force some time ago (years) doing a single rotation for circumference of the tire and I really don't recall the answer BUT a good while ago I was told to use this for "rolling radius" and it's usually been very close.

Advertised diameter less 1/2 of the tread depth x .96/2 but I've never passed that on anywhere. I can't presently measure mine but it seems like it's actually a good tool.

Your F1 315/35R17 25.7 - .16 (1/2 - 10/32) X .96 = 24.52/2 = 12.26

It seems a match or very close! Air pressure!
