ESP, Check brakes and Speedtronic Malfunction after installing new wheels HELP
I just installed 19" wheels today and then i took it for a drive in the wet and it came up with Check Breaks, Speedtronic Malfunction and ESP Defective Malfunctions. Is there anything i can do about this? Do i have to reset the computer or something as i has 16" wheels on it before?
Thanks

Which tyres do you have on the wheels? Is the diameter the same on all?
285/30/19 Rears
255/35/19 Fronts,
The set was purchased used, and the rears have about 20% tread and the fronts have about 70% tread.
All tyres are Michelin Pilot Sport
EDIT: I just went down to the garrage then and turned on the car and all the error messages have gone, but im not sure if they will come back, should i disconnect the battery and then wait half an hour then reconnect and see what happens?

The front tyres are 1.1% bigger by diameter if I calculated correctly. The tread difference makes it about as much worse. If the message keeps away, ESP must have adapted to your current tyre size difference (I don't know how much it can tolerate).
By the way, pretty dangerous to have that low tyre tread at the rear while the fronts are good. The opposite would be safer.
