Just a stupid question really. On my tyres it says the min - max pressure should be; 345 - 55 KPa 50-75 PSI 3.4 - 5.1 bar I've attached an image of the foot pump I have. I take it the black is the reading in PSI and the red is the bar reading? I usually pump the tyres up to the 5 on the bottom red reading which I'm presuming is ok. What would happen if I pumped the tyres up to 6 bar? Would this affect the handling of the bike, or does it just put strain on the inner tube leading it to burst if, for example, you go over a pot hole?
