Wheels

I'm looking at some Alcoa Challenger wheels. I think I may get the 16x8. I don't however understand the difference between offset and backspacing. I thought they meant the same thing. Does anyone know the difference between backspacing and offset.

Well if you can find something about backspacing, here is the best explanation of offsets I have ever found:

Backspacing is the measurement from the mounting pad to the inner edge of the wheel.

Offset is the distance from the mounting pad to the centerline of the wheel.

regcab02HD, I have the MickeyThompson Challengers - made by Alcoa - same wheels - 16x8 - backspacing is 4 9/16" - really nice wheels - you can put an E 10ply tire on them

Hey gandolphxx, I looked at your site and that's the exact setup I plan on putting on my HD. The Challengers and the TRXUS's. I couldn't find any pictures of your Avy. with the TRXUS's though. I saw the Challengers and they looked good. Do you have any pics of the TRXUS on your Avy.

Your running the 265/75/16 right. Did you have to turn up the torsion bars any?

A funny thing happened on the way to the forum :blush:

I neglected to check the front fender well - it is very tight on the 2500 AV - I can just barely run 265/75/16's with the torsion bars cranked.

I also decided the drag racing was fun - installed Whipple and ... I am now debating putting on Pirelli Scorpion Zero 285/65/16's or BFG KO/AT 275/70/16's - they will fit, I think

Your 2500HD will not have these problems - If I had the room I would have a set of the TrXus tires in a heartbeat.

BTW: the wheel place that I special ordered the MT's from was skeptical until they arrived - the shop guy took one look and said "sweet - finally a real set of wheels"
