1971 cuda wheels and tires help

[frenza]

Hey guys I have a 1971 cuda with an 8 3/4 rear end. I need some help finding the biggest tire size i can fit without having to touch the quarters. I see alot of people saying you can fit 275 and some say you can't go more than 255. If I can run a 275 tire what off set and backing space would I need? I plan on putting 15x7 in the front and 15x8 in the back. Thanks for the help.

There is a lot to this, the optional tires sizes are limited in 15" The most common tire is the 275/60/15 but I hate the look , the tire is too tall IMO .
I was able to find a Nitto 275 50 15 which fits well & is not too tall , also it has good traction .
If you go to a 17" rim there are a lot more choices & 295 should fit as there is a lot less sidewall bulge .
The other good option is to use offset leaf spring hangars & move the springs inboard this will allow up to 305 width with the right offset rims or using the 60s B body diff which is narrower
