Hey people,

I want to start off with mentioning that I searched the forums but couldn't find anything suitable that answered my questions/thoughts.

Last year I bought a Felt S22 (Triathlon/TT bike) mainly for future Iron Man distance triathlons and to train myself in/getting used to stay in an aero position for 180km. I took some rides with it in the fall never really thinking about the tyre pressure, which I actually never have done with my road bikes... I have always pumped them til' I feel they are really hard.

But today that changed, I ordered a digital gauge last week that I received today so felt on the tyres and inflated them til' they were hard as usual(meaning each pump = pretty tough). Took my gauge, checked the pressure which gave me 54.3psi on the front and 55.9psi on the rear. Knowing the tyres I use (vittoria Zaffiro) say the min. pressure should be 100psi and never over 140psi (must be hell of a bumpy ride with 140 on mediocre roads?). At this moment my jaws hit the ground, the tyres are hard, I doubled checked the pressure a gazillion times.

I mean it feels like each time I press the pump to inflate I'm waiting to become deaf out of a mad tyre explosion (at 55psi ). So am I just a rookie with the topic 'tyre pressure' that have been riding on a bogus pressure for a while?

The digital gauge I use is:

The readings are nearly perfect each time meaning the difference is at most +/-0.2psi

Waiting for replies!
Thanks in advance.
