Has anyone measured the size (diameter) of their Duratrac tires. Have you found that the actual diameter of these tires when they are mounted to be the same size that is reported under the tire "Spec" section on Goodyear's site? For instance the reported outside diameter of a 285/70R17 on the Goodyear site is 33.0". Are these tires running a true 33"?

 

I have 33/12.5/15 Duratracs and mounted they only measure a little ove 32 inches....I love the tires anyway

 

Probably not gonna measure 33", or anywhere near Mfg height. It depends on air pressure and wheel width, so everyone's results will differ.

I can't speak on the 33's, but I have 315/75r16 Duratracs on 16x8 wheels, and brand new at 30 psi they measured right at 34".

Hope that helps.
