I read all of your tech help and appreciate the details and wealth of knowledge concerning corvettes out there. I anticipate having to have tire work including balancing and tire changes done in the future and will probably remove them myself and transport the wheels with tires to a proper place. My question is what should I look for in tire changer equipment and technician that would be the best for my chrome Z06 wheels and non run-flats. Are there types of tire changers that I should stay away from? Are there types tire changing machines that I should use? Thanks for any comments.
