had some tyres put on about a month back, anyway i checked the pressure today and they were all at 38psi, which i thought was high so i reduced them to 30, have i done right or wrong? the car drives better tho
usually when u have new tyres put on, there is some psi loss but not much. Can't account for the high psi reading; maybe the tyre shop set this without proper attention?
what size are they? if they are 17's, 31 at front and 28 at rear (non-lowered) should be fine. If your car is lowered, that's another scenario.
