Tyre pressures...?

Can anyone point me at what tyre pressures I should use on a Gazelle hybrid lite ally framed
bike?? It's on 37 x 622 tyres, and I've set them to 80psi for a 14 stone bloke??

The tyre sidewall will (almost always) have the recommended pressure for the tyre on it. As long
as it's in that range you should be okay: softer gives you a cushier ride but makes you do mere
work, pumping them up like bricks lowers rolling resistance noticeably, but OTOH you feel the
potholes and bumps a bit more and the bike can be rather skittery if you pop off road onto a
gravel track or the like.

Hi Pete,

Unfortunately, this is a dutch bike, and they require a reflective sidewall, which is thick enough
to obliterate the writing - I just about managed to read the size, which is in big letters ):

Any takers??

Looking at similarly sized Continental tyres they suggest a pressure of 4-5 bar (approx. 60-70 psi).
If the roads round you are potholed you might want to be at the upper end of this range to avoid
snakebite punctures.
