No problem at all with this fitment. As noted, the regular SS can come with Magride and it is otherwise identical to the SS 1LE in terms of wheel/tire fitment. I actually run the base-model 18x8.5 et32 wheels with equally-tall 245/50/18 tires. Those tires are the same width and diameter as the SS fronts, but the SS wheels sit 12mm further outboard than mine...and mine still clear everything.* You'll be completely fine.

*Except the 1LE air deflectors for the front brakes, which are screwed to the lower control arm. At full steering lock, my base wheels rub those. I just remove the deflectors for winter. The SS wheels won't hit them at all because they are bigger in diameter and have 12mm less offset.
