The stock Raptor wheels are charcoal grey painted + clear coated. 17" x 8.5", 6 lug x 135mm, with 34mm offset( 3.41 front space, 6.08 back space) The frontspace and backspace measurements are based off the rim's full section width edge to edge(9.5" approx.) where the 8.5" width rating refers to inside edge to inside edge(tire mounting surface). The wheels are hub-centric which means the weight of the rim is supported by the hub bore(the hole in the middle) rather than lug-centric which would use 60* conical lug nuts to center the wheel and support the weight. The Raptor's spare tire rim is colored flat black to differentiate it from a normal wheel with TPMS installed- the spare does not have a TPMS sensor. The Ford Racing Parts wheels for the Raptor are similar in style except they are black in color and have a Ford Racing center cap rather than SVT. They are the same specs as stock.
