Wheels, Tyres and Brakes / Re: Confused by tyre pressures
« Last post by PH on July 10, 2026, 07:53:12 PM »I have a tyre pressure app. based losely on the idea of a 15% drop (Compression) that suggests for those criteria, and smooth surfaces:
71 psi front
76 psi rear
I'd probably use 70/75 as a starting point and adjust from there. There's a margin of suitable pressures, the perfect ones depends on various factors, the tyre construction, riding style, priorities, and of course personal preference.
EDIT - Funnily enough, 70/75 is the recommendation in UKTony's link, though had you and bike been 20kg lighter, or heavier, the app would have given a different result. I am a bit suspicious of pressure recommendations that don't consider load on the tyre.
