Tyre pressure opinions please.
Moderator: robbosmans
Im riding Continental GP4000SII in 25mm. They measure out to approximately 28mm.
I am 67kg, bike is 7.3kg (sorry WW), other gear would proably be a kilo.
What is the ideal tyre pressure I should be running?
I currently use 90 front 95 rear

Less is more.
I'm 73kg, bike is around 7.4kg with HED Ardennes + and Vittoria Corsa 25c. I'd say mine would measure around 28mm and I currently run 65psi rear / 60psi front.

That is impressively low psi. I find if I go below 80 psi my tires deflect/displace too much in hard cornering. I am 80 kg though so that is a factor but still...
Using mostly 25 or 28 mm on various wider rims.

I wouldn't go lower on the front, otherwise, when out of the saddle, the front end tend to feel 'soft', as if there was a fork with 1 or 2 cm of travel.

I'd go as low as you can until you bottom out on bumps and then increase 5 psi, 10 max. I'm 80kg and ride those exact tires on my bike at 75 psi front and 85 psi rear depending on road condition of where I'm riding. Spectacular feels and exceptional handling in the corners.

Depends quite a bit on the wheel profile. I'm heavier than you and run those same tires on wheels with 20.5mm internal width. Generally I'm around 70 psi. The same wheels with 23c tires, I'll run around 80.
With narrower wheels, I'd increase the pressure proportionally.

I'm about 65kg, use about 65psi on 25c Vittoria corsa's (17mm internal rim)
Super smooth on the rubbish roads around here, haven't got any pinch punctures. Only time I notice them being squishy is in the back when climbing

73kg, Schwalbe Pro One 25mm on 21mm internal width rims, running 65/75psi F/R.
I tried higher psi like 75/85 or even 80/90 but found that it's too much for the relatively rough road surfaces in HK.

Tbh, ride quality on Conti Gp4k doesn't really improve with lower pressure, so run them as hard as you like. They're fast though.
