'69 Barracuda w/ spring reloc, max rim/tire width? AdamR??? Anyone??

I have the actual spring relocation kit, not the offset hangers. Plan to run some drag radials on it. Was hoping to fit some 295/50/15's. The different ones I am looking at have a section width somewhere between 12-12.5. It would be REALLY close. Looks like I will probably just stick with some 275s. Don't want to take a chance with it rubbing.

Thanks for the comments guys!!!!
