What's the widest wheel and offset that will fit on 68 cuda

On a Barracuda there's more room on the outer side. When you start going wider the backspace needs to decrease a little.

The lower profile tire don't have the side bulge as a 275/60/15. And the 60 series fat tires will side flex when cornering.


Kris,
Are the top fender lips rolled?

Those ET are my next rims. What diameter/width and backspace rims. What tires: Rear AND Front?

What rear end width and brakes?

What front brakes? Stock spindles?
ahhh, didnt assume he was staying with a smaller diameter wheel. So yeah the sidewall flex will hurt him much more then someone running a 17 or 18 :)

yeah i rolled the Lips almost flat up top. Also running a dana 60 (hub to hub measurement was 57 1/2) in the rear with QA1 adjustable shocks and Hellwig rear sway bar and Dr diff offset shackle kit to work with the hotchkis leafs. Up front im running PST tubular UCA and QA1 Tubular LCA with QA1 strut bars and PST torsion bars and QA1 adjustable shocks. Below are the specs from my order.

up front im running a 245/40/18 (tire is slightly stretched on the rim, will get 255 on the next order) and in the rear i am running a 285/40/18 (was going to go 295 but tire rack was getting rid of the 2016 cont extreme contact tires and only cost me 120.00/ea rear tire, couldnt pass the deal up) the rear section width measures almost the same as my buddys 295 bfg's. i am running the 73+ disk brake setup.
