The other issue is the sensors on the new tires and wheels. I ordered them from custom offsets, with the new sensors. The tires have 2 valve stems each. One as normal for the air, but there is another on the back side of the wheel. They seem to be too long cause the front wheels have started to shear off part of the valve stem. I am assuming it happens when I turn, somehow hitting the brake calipers or something. Custom Offsets has suggested I get shorter stems, but my dealer and local tire shop don't have them. Suggestions??
