How tyre pressure can influence safety
Driving on under-inflated tyres leads to deterioration and damage of the tyre structure and may ultimately result in rupture and rapid deflation. Even after re-inflation a tyre that has been run under inflated can still rupture.
If below the vehicle manufacturers recommended tyre pressure, there is a sharp increase in the risk of aquaplaning.
A difference of 1 bar, or 14 psi, from the vehicle manufacturers pressure recommendation can increase the braking distance on wet roads by 11 metres. This is more than 2 pedestrian walkways!
Tyres under inflated by 14 psi (1 bar) have increased rolling resistance, which increases fuel consumption by 1 full tank of fuel per year
