[Retro]

I did some reading on this subject as well, my opinion would be to use tire covers when not in use and try and take the weight off when stored for long periods. I read when the tires are being used the tires natural waxes or oils and protectants surface from flexing, and like you said if you wash them it removes them. I would be curious if someone has something to put the same elements back on the tire once its washed. I don't think it's going to make me stop washing mine, but up north here we don't get the heat like in the south. I also keep mine indoors when in storage.
