I have just purchased a new floor bike pump.While checking the tyres on my road bike the gauge reads for the rear tyre 0.95 bar , 13.5 psi.the reccommended pressure is 130 psi, maths not being my strong point! Am I just reading it wrong and not moving the decimal point so the actual pressure of the tyre is 9.5 bar and 135 psi.Sorry if this makes me seem a bit thick but I am new to cycling and want to get it right, better safe than sorry and all that. Thanks.
8.5 or 9bar is a usual maximum recommended pressure for road bike tires (23mm width). Depending on your weight and demands on comfort something between 7 and 8.5bar is usually right. Just be aware that road bike tires lose pressure pretty fast so you have to refill them every week or so.
They should feel very hard at 8bar. If you can pinch them it’s way too little (though it’s hard to gauge pressure by hand).
