I want to end the guessing game and worries for AWD differential being damaged.
I know this is gray area for most people, here is a simple calculation for Circumference:
( people that are not good in calculating or want easier and quick calculations like plug and play see bottom )
Circumference = 2 π or
Circumference = π D
I am assuming everyone knows π =3.14159
I would think most people know how to calculate the % so we need to stay within 1.3% for AWD to protect differential!!!!
I have seen people do up to 1.8% or more but this is up to individual how much they want to risk.
To make it easier on everybody, I am attaching this tire size comparison which is basically: plug and play
There is so much more info that everyone can use.
I am sure most people will appreciate this.
