In JAPAN there are several types of fender flares are available now, those are 90mm, 80mm, 70mm, 50mm and 35mm.
The reason why there are so many fender flares in JAPAN is that tires sticking out from fender flares is illegal. Therefore, we must install extra flares to cover tires in order to meet Japanese DOT regulation.
