Hi gurus,

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??

Cheers,

Steve

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.

Pete.

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.
