I've got a flip bike that needs some new 27" shoes and the low cost spectrum of the tire selection seems to be less available than the last time I have tried to buy them.

Canadian Tire doesnt seem to stock any of their Kenda 27" tires and MEC has dropped the $10 Cheng Shin 27" but do carry some blackwall Kenda K35s and Contentials.

The UK online retailers either dont have any available or have the Continentals. Seems like just a couple years have passed and the local selection has gotten worse.
