Thanks for the helpful info. I am member of the http://chryslerownersclubqld.com/site/ I also have an Australia Chrysler 1969 Valiant hardtop (Aussie version of the Dodge Dart ) but that is another story. Chrysler vintage cars (many Ford A models, Chevs, Whippets, Humpmobiles, Fiats, etc) are very thin on the roads here in Australia and hence why I joined aaca.com to get valuable info on my 62. I am not planning on removing the tyre off the rim, just learning how to change the tyre/rim with the spare. Can the tyre come off the rim accidentally? Keep smiling, Moe
