Hiya, my timing on the answer has to do with shipping rates - I'm in Canada. Like tester quoted, and like I said, the tires have 26x 1 1/2 for 26x 1 3/8 rim printed on the side. These are the first that I've seen that don't have an ISO/ETRTO designation, but they most definitely are 37 x 590.
Riiight, thought you were one of them Londoners. Anyway, the delta cruisers were found at spa in 37-590 for mega cheaps, and they are cream which the GF likes the idea of.
