Looking for diameter or radius on 12.4s vs 13.6s anyone have this info or no of a chart ?

According to me miller a 12.4x38 has a radius of 59 inches & a 13.6x38 has a radius of 61.5 inches & that is on a firestone field & road tire

Varies from one maker to another..in other words..do not mix and match without actually knowing or measuring..

My "Good Year Titan" 15.5x38 are nearly 2 1/2" taller than my same size Firestone tires..both new..
