Re: 15x10 rims on TJ and front wheel bearing problem?
Yes, it will accelerate wear. HEre's why:
1. When Chrysler designed your TJ, they used rims with certain offset and backspace to clearance the calipers, steering components, and balance the load on the wheel bearings. When you put on a wider tire with a different offset, you are increasing the lever arm against the bearings, maikng them work harder, and failing sooner. Larger tires will exacerbate the problem.
2. The same holds true for steering components.
3. Think about a Dually pickup. The front wheels bulge out of the tire, right? Next time you see one, look inside. You'll see that the wheel is mounted to a cast hub that holds it to the axle. This configuration is necessary in order to keep 1 spare tire that fits all positions on the wheel, and the cast hub is necessary to position the line of force as close to the center of the wheel bearings as possible.
4. Wheel bearings are tapered roller bearings. They are the most cost effective and one of the strongest ways to deal with both radial and axial loads. By changing the offset to a good degree, you apply the force on the bearings from a different angle, also accelerating wear.
5. Why do you want 10" wheels? What size tire are you going to run on that? I'd call that an awfully wide rim for any tire less than 12.5" wide.
hope I shed some light for ya here.
