Needs advice of changing wheels

Post by WizzEssex » Mon Feb 20, 2012 11:34 am

Hi guys- can anyone help please:
Thinking of replacing my original 16" allows (with RFT's) for some 17/18 with non run flats (2005 Z4 2.5) - does anyone know if fitting new wheels and tyres will make the 'tyre-flat warning light' stay on or will it reinitialize to the new wheels and tyres ok??
Any thoughts much appreciated- thanks-
Wayne

No problem. Have had 16 on with winter tyres and changed to 18 for summer use and no probs. Tyre flat indicator works on measuring the didiferential in rolling radius caused by deflation. Where this remains constant across the 4 axles no problem - tyre deflates, rapid change in rolling radius on one wheel and TF warning comes on.

Oh and welcome to the Forum. Put something in the Newbies section about you and your Zed :thumbsup:

You just need to reset the system after you have changed the wheels, tyres, or altered the pressures.

We are all assuming that you have a European spec car that uses the method stated by Alanj and not the American version that uses an individual sensor inside the wheel, since your country is listed as Macao :idunno:

US spec Zeds prior to 2007 have no sensors in the wheels. Just for the record.
