The low profile tires peaked my interest. I have a 2004 tandem Aluminum Slide On (sorrry ) and I am very happy with it except for the junk Towmaster tires they used back then. (size f65-14). They setup the fender spacing such that I have to move them and maybe shift and axle to use a standard 205-14 . :-(. I really want to buy some Goodyear marathons since I hear good things about them. What tires are those? I have seen a couple low profile tires on trailers but they were not actually trailer tires (ST).
