New 18" tires rubbing bad-what to do?

[bark3rd]

These are the knockoff Cobra r's but I think I found out what is happening. When I pull in to my driveway I make a sharp right and hit the bump where the slope of the driveway starts-yesterday I heard it rub bad when I pulled in quickly. I will just have to be mindful of sharp right turns followed by sharp bumps I guess. These wheels are made by "Verde" specifically 'for mustangs, I doubt the offsets are off. I think the 275's are just a bit much (the wheel dealer did tell me they use 265's when they sell wheel and tire sets). Of course just like when buying anything for this car everybody had a different opinion about what would work. I hope my mistake being read about here will help some others who are about to get Cobra R wheels to go with 265's up front (the 275's are fine on the rear). Oh well, whats $600 (I'm going to cry now).
