Wouldn't ya know it, I'm running 275/60/15 BFG T/A's on 15X8 Draglites with 5.5bs on a 90LX. I had to bash the **** out of my inner wheel wells. I haven't rolled the fender lips, but it's definitely a good idea. I've taken a few chunks out of my tires over some big bumps.
sure you don't want to run 275/50's? I had 275/60's on some draglites and it was way too big for my tastes. I got some 275/50/15's and I like it. I've had both and here are some pics.
This is just a question, NOT A CRITISIM, you do what you want with your car: What made you choose 4.56's and a 28" tire over say a 4.3* or 4.10 rear gear and 26" tires?
