I have been getting an a lot of flats lately and was wondering if my tire pressure could be the problem. The tires have a maximum pressure of 125 and I keep them at 120. What is the appropriate tire pressure? I assumed keeping it close to the max would reduce pinch flats but am not sure if this is causing any other issues. Also can someone recommend a good tire for urban commuting? I am currently using Kenda Kontender 700x25.
