Decades ago I had so much trouble trying to buy a 26 X 1 1/2 tire that fit that I quit riding the bike. Stores kept selling me 26 X 1 3/8 saying they were the same. (This was years before internet, research was difficult back then.) My 26 inch bike was 650b. Now the marketing pros are trying to resurrect 650b by calling it a new size, 27.5.
