Advan RGIII 5x114.3 18x8.5+31 Gloss Black Wheels for the 2012 Acura ILX

This 18×8.5" setup sits at the lower end of the ILX's aggressive fitment range, which accommodates up to 18×9.5"; the +31 offset will pull the wheel closer to the fender than factory 17×8" specs, requiring fender rolling on most trims and likely coilover lowering to achieve the stanced appearance shown. Slight tire stretch is feasible at this width, though a 225–235mm tire will maintain safer sidewall support; moving to 245mm is possible but demands verification against your specific fender clearance after any modification.

The Advan RGIII 5x114.3 18x8.5+31 Gloss Black is one of the most popular aftermarket wheel choices for the Acura ILX platform.
