Actual Tire Size BFG AT?

[millerfish]

I have read some comments about some tire brands varying a lot between actual and marked tire size. Has anyone measured your BFG TA tires. Specificly 265/75/16. That size should measure 31-5/8. My current BFG rugged trails measure dead on the marked size.

My unused spare measures 31" and the tires under my FJ measure about 30.5", they're at 40k.

A 265/75r16 measures at 31.6", although this can very from tire to tire. A Cooper ST Maxx measures at 32.01" which is the largest I have seen in this size.

Just put a set of 265/75/16 KO2s on my Frontier Saturday morning. They are dead on true to the listed size of 31.6 inches.

My general grabber AT2 in 275/70R18 have a listed height of 33.2" and an actual height on my truck of 32.2. If you look at the revolutions per mile calc, that takes static load radius into account, and you can back into what the height on the vehicle should be.

For example, my tire on TireRack is listed to be 626 revs per mile. 5280' per mile / 626 = 8.43' per revolution / pi (3.15) = 2.68' diameter * 12" = 32.1" on vehicle.
