Tire mounting can be made easy with a mounting board. For an article on how it is done, go to the web site of the Santa Anita A's of Arcadia, California at
www.santaanitaas.org. On the home page put your cursor on "Technical Reference", my name will appear below, click on it.
A menu of technical articles will come up. Scroll to the heading steering, and then to tire mounting. The article is a pdf file that you can down load and print out.
