So it is simple. Basic tires are clinchers. Thank you for clearing it up! So most tires are 120 psi with some out there where you can put in 170 to 200 psi?
not if you want to ride them on the road - tyres for the track are different beasties and I know nothing about them .
tyre pressures are a whole world unto themselves and more to do with weight
ie if you are small and light then between 95 - 100 psi
- normal then between 100psi and 110 psi
- heavy ---------------- 110 and 120 psi
but that´s just rule of thumb , for example mavic say not less than 7 bar but no more than 81/2 - 9 bar : 100 psi min , 130 psi max .
low pressure : more grip , more resistance but better in the cold and wet .
high pressure :less grip , less resistance and a skating rink on a cold wet day
low pressure : more risk of pinch flats and , some claim , more punctures
high pressure : no pinch flats but a hard ride and the rear wheel skids easy
basic rule ? if no recomended pressure then max rec less 7 - 14 psi
mostly it´s suck and see - see how it feels and experiment , like seat hight it´s a very personal thing .
good luck
