I installed the 30c version of these tires with tubes on standard Wabi wheels, which are intended for tires up to 32c. They look and feel awesome now that they are on, but required an inordinate amount of force to get on. Seriously, I have not had such a hard time before. Must just be a combo of that tire and rim, along with the use of tubes... but worth noting as the stock Kenda tires went on and off easily. Great price and service from the Bikesmiths.
