probably a stupid question

[feybrand]

if i change my normal wheels for some aftermarket ones will it efect my runflat sensors

[frylock]

Probably. When I changed my wheels, I had to reset the runflat sensor. It's easy to do--just hold the button by the emergency brake while you're starting the car.

If they are non runflat I think that the light will stay on... You may need to go to a dealer to have it switched off...

[feybrand]

no they r runflat thanks for your help

[murmini]

The runflat sensor is really misnamed, it simply looks at rotation of the 4 wheels and reports if one of them is making more rotations than the others, indicating a deflated or partially deflated tire due to it having a slightly different circumferance and subsequently making more/less revolutions than the others. It does not have any special relationship with runflats. So, reset the sensor and motor on.

As murmini says the runflat indicator is actually the abs sensor and is looking for one wheel rotating at a different speed to the others. There are no pressure sensors built into the rims or any such nonsense. And that popular myth that tyre fitters like to spread about the indicator being permanently on if you change rims or move to none runflat tyres is nonsense.

tis true run-flat indicator works fine with any size wheel or run-flat or non run flat tyre just reset it with the switch under you hand brake keep it pressed the light will go off will still come on and work as normal if you get a flat

[ONED]

That seems to be that sorted then!
