Note: Alumilite wheels are precision fit. In the case that they may seem too tight, this may be due to residual polishing compound. Carefully remove the compound to gain proper fitment.
Note: Part number 355-9047 features both 10mm and 12mm bolt holes.
The wheel size listed consists of several parts - the first is the Wheel Size, for example - 12x9. The second is the Bolt Pattern, for example 4/110. If two are listed, such as 4/110-4/115, then that wheel has a dual bolt pattern. The last part is the Offset, for example 6+3.
When reading the Offset, B = Bell and N = Nose. The bell shape creates maximum clearance inside the wheel for brake and steering parts. The nose shape has a smaller drop center for ease of tire mounting.
