Pretty sure I am going to order some 3" wheel spacer for my B2620. I have the R-4 tires and was thinking about having the front ones loaded with Rim-Guard while i have them off. ( Rears are already loaded.) They seem to lose air - when I think to check them they usually won't even register on the gauge. Does anyone know are they tubeless? I am assuming so. Can they be fitted with tubes and loaded? Would it be worth the effort?
Thanks,
Tim
