I am trying to select a 17in wheel and tire for my Challenger. It has stock suspension at this point. Front has a 73 Dodge Aspen disc brake conversion. I want to run the widest and most deeply dished wheel I can run but I have not been able to find and specs online other then tirerack.com. What have people run as far as offset and backspacing for maximum dish and tire width? Any help would be appreciated.
You can't have both. You'll have to narrow your rear end to get a larger dish with the widest rim you can fit. Stock suspension will limit your width in the back. The front is sheetmetal. Especially if you lower the car some.
AFAIK I'm running some of the widest tires front and rear. I have 275/40s on 17x9s.
In the rear my offset is 0 (5" backspace). 5.25" would be better, but I can't really get narrower spacers and be safe. Either way, I have no rubbing.
In the front I have 5 1/16" backspace (I skimmed my 1" spacer to a 15/16") and I only rub when I'm fully locked and I'm articulating a suspension (going into and up my parent's steep driveway from the street).
I'm also running slight negative camber and only expect to improve that eventually with either Moog offset UCA bushings or just finally biting the bullet on some Hotchkis UCAs. Either way, it's TIGHT in front.
