285 35 18 RSR's (don't get them, I don't know what all the fuss is about) on 18 x 10.0 + 12 wheels. No scrubbing issues on the inside, however when hard up it and hitting a decent bump, the tyre will hit the guard slightly. The 285's did bulge a bit on the 10 inch rim/RSR combo. A 275 would be a better fit.
