I would like to get some information / advice When selecting the offset and backside spacing for new wheels. The wheels I am looking at are a 0mm offset and 4" backside spacing. Will this effect the turning radius and cause wheel rub?
If if has a 0 offset and 4" backspacing, it must be an 8" wheel. A 4" back spacing will put the tires further out from the veh than is probably necessary. With a 33" tire you can probably get by with 4.5" back spacing and probably even 4.75". 5.25" to 5.5" is too much. They will rub in turns. For some reason people try to figure out clearance based on offset. All offset does is tell you how far the verticle center of the wheel is from the plane of the lug bolt's face plate (end of the axle) where the wheel and axle end actually touch - 0 being dead center. If you had an 8" wheel with 0 offset, the end of the axle meets the wheel 4" inside the wheel. A 10" wheel with 1" offset would place the inside of the wheel at the same position in relation to end of the axle, so it too would have a 4" back space, but would place the outside of the rim 2" further away from the veh.
