Tires wearing on inside

Make sure that the coach is loaded, when you do the alignment, just like it would be when you travel.

I had mine aligned by Superior Spring in Hamden on State Street. They came recommended and when I went there they had dump trucks a rv and a fire truck there. Looked good. I handed them the specs from the SuperSteer site and told them that is what I wanted.

Gjac.....If they're wearing the same on both inside edges, that is generally a toe-in/toe-out/ adjustment. Typically, the inside wear is too much toe-in. You can do a poor mans check and to see where you're at by measuring from tread center to tread center on both wheels on the back side of the tire and then the front side of the tire. The difference will give you either your toe-in measurement or toe-out measurement.

You should have the coach aligned by a good alignment shop. Do what they call a four corner alignment. They use a laser to make sure the rear wheels re running the same direction as the front. Typically, a truck alignment shop will charge $150.00. Once the alignment is completed, the tires will continue to wear, even though the alignment has been corrected. The reason for this is that the area that is worn down, will now scuff off rubber which will wear as fast or faster than before. If you have a good set of duals, you could move both fronts to one side of the coach and make that one side your two new fronts. DON'T mix the fronts on the rear, keep them together as a set, otherwise you'll have two tires of different height (example....don't pull off both outer duals and swap for the fronts, just use the duals on one side).

Gjac, tires wearing on the inside edges is negative camber, but this can also be caused by too much toe out - or a combination of both. I have a 1993 Georgie Boy built on a Chevy P30 independant suspension. When I had it aligned last,the camber was set to +1/2 on the left and +1/4 degree on the right side. The caster was set evenly on both sides at +3 degrees with total toe set at 1/16 toe-in. Bill
