The Kendas have worked fine- but they have a max. rec. pressure of 40 psi. I am not a small man. I would like to use more psi in the tires, but I dont want to exceed the recommended pressure. The Felt tires have a max psi of 55. I think that would help me not flatten the tires as much and there may be less rolling resistance. If the Kendas allowed more pressure, I would gladly use set after set.
