Well, that will make the outboard clearance better, although I'm super happy to be rid of trying to find SBP drum brake parts. I guess everything is available at the moment though.
So, the 275/60/15's should fit the wheel well just fine, you'll just have to decide if you want to stretch the tires on a set of 15x10's. Largest recommended for most manufacturer's is a 15x9.5 for a 275/60/15. The 295/50/15 will fit the rim, and probably won't rub with your suspension set up. But that will still be a ride height dependent fit, and it will be tight everywhere. Some adjustments will undoubtedly be necessary depending on your ride height and how much your body tolerances vary from side to side. One side is almost always tighter than the other, and when you're pushing the limits that can be an issue.
