Ha Ha HA so his tire is wobbling so much the air resistance makes it hot
to the touch. Don't stick your hand out the window it might burn up.

He hasn't tried to do anything to fix the problem. He is relying on a
mechanic to do all the work. The problem didn't exist until the mechanic
did a brake job. That is when the trouble started. The brake line is still

that no theory is going to be very good.
