Whats the largest wheel and tire size I can put on the rear of my 69 El Camino without doing wheel well mods?

What diameter wheel and no mods meaning not even rolling the lips?

I'M not sure if the wheel opening is the same in an elky, but I stuffed a 295 50 15 into my velle.. Thats on 8" ralley rims..

Wheel and Tire Forum (http://www.chevelles.com/forums/forumdisplay.php?f=17) has a lot of this info.

I will use a 15" wheel and would be ok with rolling the lip. I forgot you can do that.
