My old buckshots that I sometimes have on the Power Wagon are even worse... I think the whole size designation is "8.5x16." Makes no sense, cuz they are 11-12" wide, and 36" tall...

305x70x16 = Calculated Tire OD 305/25.4*2*0.7+16 = 32.811"

285x75x16 = Calculated Tire OD 285/25.4*2*0.75+16 = 32.830"

True tire size...is another matter.

I wrote this up a while back when I was bored. But, I thought this would be a good place to share. How to convert metric tire sizes.

for the 305/70/16's? They must be using the new math or some such, as I come up with 32.8 as well. Of course, inflation pressure, and rim size will change that as well.
