Wheel Offset Calculator

Post by FRUNKenstein » Mon Jan 08, 2018 6:26 pm

I often see people ask "Will these wheels fit on my car?" I'm wheel offset challenged. Can one of you guys explain how to calculate offsets for both narrow and wide body cars?

Pelican Parts also has a fairly exhaustive writeup on wheel fitment:
https://www.pelicanparts.com/techarticl ... itment.htm

Understeer: You will hit the wall with the front end.
Oversteer: You will hit the wall with the rear end.
Horsepower: How hard you will hit the wall.
Torque: How far you will move the wall.

"If you see the barrier you’ve driven into, that’s understeer. If you hear yourself hitting the barrier, it’s oversteer."
-Walter Rohrl

2002 Porsche 996 Carrera - bare bones basic, but still a blast to drive! Heck, I don't even have PSM on it. Ha!

Thanks b3freak, I had not seen that one. This is what I used when checking my last wheel purchase.
