I usually go to tire track and compare tire rotations.

How do I figure out the tire rotations per mile on I tire zi do not have?

I have 16.00-20 tire and can get a deal on some 395-85-20.

The same rim size BUT what about width , sidewall and overall height?

395/85R20 = 46.4X15.55R20
Diameter = 46.4"Width = 15.55"Wheel = 20"Sidewall = 13.22"Circumference = 145.8"Revs/Mile = 434.5

Hope that helps. Eric

And rim diameter is 16 or 20 inch?
