That's the best way to do it...the only rubbing I could see you possibly having, and it's a stretch with 275's, is that you might rub your inner plastic fender liner after compressing your suspension when entering a driveway or street at a grade.
My Mach 1 has 295/35's on 18x9 rears and they do rub when I enter a graded entrance. Doesn't do any damage as I'm traveling slow, just makes a nice rubbing noise, sounds like the car just shat it's pants lol.
