wouldn't it rub if i go over big bumps if it is sticking out? i don't have that issue...
Probably we are talking about different things: my numbers of width / offset refer to the rims position. The outer border of the tires is another thing, related to "beefy or stretched tires", tires brand, etc... Rubbing or not (on the rear) is more related to the outer border of the tire than to the rims width.... For obvious reasons, the front wheels never touch the upper part of the fenders, even if they stick out…. 3 cm…. at least you change significatively their overall diameter.
