Advan RCIII 5x114.3 18x8.5+38 White Wheels for the 2015 Honda Civic Si

The 18x8.5 +38 offset sits within the Civic Si's aggressive fitment range and will deliver a noticeably wider, more filled-wheel-well appearance than factory 17x8 sizing. The +38 offset typically positions the wheel near flush or slightly tucked depending on suspension setup; lowering and fender rolling are common pairings on this platform to achieve the stanced look shown. Slight tire stretch (as pictured) is feasible at this width, though a 235–245mm tire maintains better sidewall support if you prioritize handling.
