What started out as a simple quest for a set of tires needed for a 'project', it slowly evolved into a minor obsession where one set became three, three turned into ten, so on & so on. As a result of this madness, I became quite knowledgeable on the various 20” sew-up tires and rims used for BMX racing. I'm sure there's others that I missed, but I'm trying to solely focus on the ones used between '77-85.
20" sew-up tires manufactured by Clement are arguably the most difficult to locate, especially in pairs & usable condition. The tread was actually applied to the casing by hand, so if they weren't stored properly, the tread would often dry out faster than the casing and begin to separate.
