tyre pressurs monitor warnings

[chrismerriman63]

hi.

I recently changed my 17" alloys for 18" with 225/45 tyres .

the recommended pressures for these are 34psi front and rear for light load.

however, the cars recommended pressures are set at 38 rear =and 41 front, which leads to the warning light coming on on most journeys

can the recommended pressures be reset without a trip to a dealer, or even at all?

There is a plate on the right side B post (between front and rear doors) which will give you the correct tyre pressures for your wheels. If that inflation still leads to a warning then the very small battery in the TPMS sensor in the tyre has expired and you will need to have the sensor replaced.
