I have 700 x 35cs that are marked to hold 50-75 psi. I'm about 235, so at first I inflated to 70... but found after 1-2 rides, they were down to 50-55. Last 2 times I inflated to 63, and the same happens, 50-55.
It seems it gets into that range and tends to stay there, so I'm pretty sure I'm not having the exact same slow leak in both tubes.
Am I right to inflate to 60-65? Is it not unusual for it to deflate to roughly the same pressure? Is it "normal" to lose 10 psi after 2 rides?
Thew bike seems every so slightly more comfortable at 50 and 65. However, I have not noticed any specific issue with the speed I can do, factoring out wind conditions.
My "rides" are 3 per week, about 10-14 miles each.
Should I be topping up before every ride?
Time to get in the saddle now, we got some SUN!!
