Confused by tyre pressures

[AdrianStone]

I've not had my Club Tour long, well, almost a year, but a lot of that time has been restoring it. I've just changed the tyres as the previous Pasela Tour Guards were worn and suffered a cut side wall and puncture, so replaced with Pasela Protite which i understand to be the new version of these, the size is 700 x 32.

The sidewall states 95psi, this seems quite hight to me, but I know nothing. I've tried reading the articles on tyre pressures, but it all seems a bit esoteric and geeky... could some please just tell me what pressures should be used please?

I'm a bit fat at 97kg, plus panniers for camping, so maybe another 30/35kg including the bike?

Thanks

You could start by experimenting with the recommended pressures given on page 40 of Thorn’s online Mega Brochure at the following link. I’m a few kg lighter than you and don’t carry heavy panniers. Others on this forum know a lot more about tyre pressures etc and when you might want to raise or lower pressures in certain riding conditions. I’ve kept it simple and stuck with these recommendations on my 26” Nomad and 700c Mercury for the last 12 years and they’ve worked for me on variety of surfaces.

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.

Thank you both, that's really helpful, I'd forgotten about the Thorn brochure and the 70/75psi seems a good place to start.
Thanks again for the help
