Now i know it seemed like a silly question as i did check online, but when the tyre is at that it was rather flat.

pee vee

maybe the gauge is fooooked then?

If it's one of theose compressor thingies that plugs into your lighter the gauge is almost certainly screwed. Used the one in the company car a few weeks back and it said the tyre was at 34psi when I checked on another (trusted) guage it told me it was just 27psi

The gauges on those wee compressor things are shite. And why on earth they put a gauge on a tyre inflator that goes to 300psi when no tyre ever made will be pumped to that, and their compressors will never even get close is beyond me.

I pumped my tyres up with a brand new halfords foot pump last year, then checked them against a calibrated gauge at work. All tyres were 4 psi out! I then whipped the gauge off and tested it, at it's highest indicated reading of 80psi, it was 10 psi out. Shocking IMO!
