Alignment Question
Just had new tires installed and alignment done. When I left the shop, I checked the tire pressure on dash and tires had 40 to 45 psi, way over the 30 psi recommended. I have dropped the pressure down to 30 psi. Since the shop adjusted the alignment with 40-45 psi, how is the alignment effected by dropping pressure to 30?

Every alignment training session I've ever attended made a point to have all 4 tires at the manufacturer recommended pressure BEFORE performing the alignment. And for every alignment that's what I do.
Having said all that, Bill Dearborn (above) is probably right. Wouldn't worry about it.

Wheel alignment tools are attached to the wheel, not the tire, so I would not worry. You can see in this pic how the tools are attached to the edge of the wheels. As long as the tires on the left and right were the same pressure, I would not worry at all.

The important thing is,that all the tires are inflated the same.
Extreme different pressures ; like 20 lbs. in the left front ; and tire 40 in the right rear ; can change the corner weights , which could change the result of the alignment when corrected; and change the way the car feels.
