I've recently sold my 240 and still have the nearly new snow tires on 240 rims sitting in my garage. I would like to use them on my 740, but I'm unsure whether they are compatible and could be simply mounted onto the 740. I simply would like to know what is needed inorder for me to mount the 240 rims safely onto my 740. I assume spacers(what size? and where are some places I could purchase them?) and anything else that's needed to make it work before the snow starts flying.

Thanks in advance, Matt
