Ford Focus Owners Manual: General information
CAUTIONS:
Use only approved wheel and tyre sizes. Using other sizes could damage the vehicle and will make the National Type Approval invalid.
If you change the diameter of the tyres from that fitted at the factory, the speedometer may not display the correct speed. Take the vehicle to your dealer to have the engine management system reprogrammed.
A decal with tyre pressure data is located in the driver’s door opening at the B-pillar.
Check and set the tyre pressure at the ambient temperature in which you are intending to drive the vehicle and when the tyres are cold.
