I recently picked up a set of Arayas with the stamping on them clearly saying they are 24x1 3/8 but when I went to put some 24" tires on them the tires were too small. Has anyone else out there run into this kind of problem or am I not understanding this tire and wheel sizing issue :? can anyone give me some advice :| ? I am pretty new to this bike rebuilding scene but have a good understanding of measuring and sizing. Thanx.
