I've just been to the garage to check all 4 tyre pressures on my mum's\nAstra. Something's wrong somewhere, it's like you're driving on ICE,\nbut weather condtions are fairly okay at the moment. There's an\nevery-so-slight feeling that the power-steering is occasionally\npulling a little to the left, like a nudge. Any ideas? Oh, and the\nfront tyres are at 31 yet look as if they are deflated a lot.
