I inflate mine to 120 (road bike.) I think 85-90 is WAY too low. You risk snake bite flats - where the tube gets caught between the tire and the rim. The holes appear like snake bites - or so I'm told - I can never find the %#$&^ holes in my tubes (as mentioned on another thread.)Originally Posted by Kalidurga
A higher psi = less rolling resistance = easier to pedal. I'm 52 years old tomorrow, so I need all the help I can get!
