Hi,
115min to 125max is a ridiculously narrow range to put on tyre.
Optimum tyre pressures depend on tyre size and rider weight
if your using the tyre drop method of around 15% drop.
28mm tyres need ~ 70 psi for an average person.
If you are heavy and exceed the 85 psi rating,
you need a wider same tyre, or a stronger one.
I don't have to explain something stupid on a tyre.
115 to 125 psi printed on a 28mm tyre is inane.
rgds, sreten.
