when I collect my car from York 5 weeks ago, took it to the local gorge to replace rear tyre as it was badly worn on the inside, drove off after having new tyre fitted and a mile down the road the tyre pressure light came on, pulled in to service station and checked pressure and had 49psi in it, put the pressure down to 36 psi and reset the button in the car and all fine again, just think 49psi is to high?
