Hi to you all out there. Having recently acquired a double sided (Presta & Schraeder) tyre pressure gauge I checked out my tyre pressures. I have a 2000 Bianchi Reparto Corse Gold Race 600 on 700Cx23 Vittoria Rubino tyres and a 2009 Claude Butler Levante Hybrid Road Bike also on 700Cx23 tyres but they are Maxxis. I have inflated both pairs of tyres until they can not be depressed with ones thumbs. I have very strong hands & fingers. This was done with a Beto 10" hand held pump.
To my absolute astonishment the tyre gauge only showed 80psi in both pairs,I could not get any more into them They both indicate pressures in excess of that. The Vittoria Rubino are to a MINIMUM of 100psi and the Maxxis to a MAXIMUM of 120psi.
The tyre pressure gauge is accurate (checked against several others that are Schraeder only,the accuracy is +/- 1% +0.5psi.
Are these pressures only attainable with a Track Pump?.
The pressures that I normally reach are bone jarring as it is,what is it with this trying to create the equivalent of solid rubber tyres?.
