No more than the guys running 2" BS with an inch spacer behind it. Even though these are suposed to be 1" it is more like 1.5". I will try and post a pic of this rim and one just like it only with a 2" BS. I bought 2 of each to use on my rig.
Did I read your post rite and you ordered two 1.5 and two 2. inch bs rims. Im asking because when I ordered four 2. inch bs rims last month they were going to be special order and take three weeks. If they have them now I would order a set. thanks Scott
