The Kenda K23 S-6 tire is a great replacement tire for older 3-speed Schwinn bicycles. 26″ x 1 3/8″ x 1 1/4″ (37-597 ISO) size. This is an obscure size found on some Schwinn bicycles from the 1960’s and 70’s. This tire is NOT compatible with 26″ x 1 3/8″ (590 ISO) rims, nor with 26″ (559 ISO) mountain bike rims. Match the ISO measurement on the sidewall of your current tire for proper compatability.
