I had the opposite problem of a 'trusted' gauge that read low by around 5 
psi. Only found out when I replaced the BT57 with Avons and had a problem 
with the valve. Bought another gauge which was marked as accurate to +/- 1 
psi. Big improvement. Now counting myself lucky that I didn't have major 
problems since I went two up fully loaded to France with pressures over the 
tyre's maximum recommended.

So how long does a guaranteed to +/- 1 psi gauge stay this accurate as most 
other calibrated items need calibrating every so often.
