It seems like the squeaking is coming from the front brakes. The wheels were changed in the garage and I live in the suburbs, so I think I can rule out rocks (and probably dust/dirt).
I will jack up one of the wheels and rotate the wheel and then apply the brake. I will be watching underneath to see if I can see what is making the noise (brake caliper and upper control arm test). If this doesn't work, I'm prepared to remove the wheel and put on the old wheel and redo the test. The new wheel/tire combo is about 70 pounds compared to much less than that for the old. I don't think the change in weight would have caused this. Rickson's web site states that the wheels are custom made to replace OEM wheels. I would think this would include the wheel offset (although I'm not sure I totally understand the concept).
this.
