Tyre pressure chart
Low tyre pressure has a negative influence on the car, and those are: much longer braking distance on wet surface, weaker resistance to aquaplaning, bad handling over- and understeering, much more difficult parking with your car ( harder movement due to larger rolling resistance), risk of sudden tyre brake while driving, faster wear, irregular and increased wear. The only advantage of lower tyre pressure is better driving comfort (better driving on potholes). Terrain enthusiasts lower their tyre pressure to increase grip.
In turn, too high tyre pressure may cause worse grip (smaller contact patch),may also lower driving comfort (lower bump absorption, higher noise level inside the car), faster wear of the car suspensions elements (due to lower bump absorption), more use of the central part of the tyre tread and higher tyre damage possibility which can result from falling into a pothole or hitting the curb. The only advantage resulting from higher tyre pressure may be the stability in the corners and lower fuel consumption (due to lower rolling resistance).
Tyre pressure should be controlled once every two weeks and before every longer trip. You will find pressure values for each car in the chart.
