I am looking at getting 2 inch wheel spacers for my cherokee on 33/13.5 and I was wondering if there are any disadvantages to wheel spacers?

hippymill said:I thought wheel spacers caused a lot of bearing wear due to pushing the bearing load away from the center of the bearing. steel wheels from crager are about $35 each, with different backspacings. Seems like a better way to go so that you aren't replacing bearings a lot.

As a mech engineer I say no, the lever arm is the same. A wheel with 4" of rim sticking past the hub (call it front spacing) has the same length lever arm as a wheel with 2 " of front spacing + a 2" spacer.hippymill said:as a physics teacher, I would beg to differ. The wheel spacer acts a lever because the weight is directed to the hub at a distance equal to the wisth of spacer. Different backspacing moves the tire out farther, while directing the weight directly to the hub, without the lever lenght of a backspacer. The idea is that if there is 500 lbs of weight on the wheel, the spacer places that weight farther from the hub, and the bearing, because the weight is transferred to the bearing at the hub.

The lever arm length depends on where the force is applied (figure the center of the wheel OD) and where it is eventually attached (the hub).
This distance is the same in both scenarios.

P.S. ME here too.
