Ve
hicles with a tyre pressure monitoring sys‐
te m: you can also check the tyre pressure using
th e on-board computer.
Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least thre e hours.
R The vehicle has tr avelled less than 1.6 km.
A rise in the tyre temp erature of 10°C increases
th e tyre pressure byappr ox.10 kPa (0.1 bar/
1. 5 psi). Take this into account when checking
th e tyre pressure of warm tyres.

driving style accordingly. #
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse

R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
