Evening all,

 

How sensitive is the TPS on the car?  Had a failure of a P7 235/40/19 and had to have a new one fitted (F/N/S),  Since then the TPS has pinged a couple of times, but all is well with the pressure, could it be the circumference differential that is causing the problem between the new and old tyres.

 

Fitted winter tyres and rims (215/55/17) this weekend and no alerts...as yet.

 

Advice, and thoughts please.

If you reset the system when the new tyre was fitted you shouldn’t get any alarms, same as if you have reset when winter tyres were fitted.

Thanks KennyR, not had failed warningse before and reset the system as per owners manual, so think I got that correct, but it triggered 3 times. Will wait and see when I refit the 19's next spring. 

i've changed tyres (19" Pirelli P7s) twice this year, thanks to punctures, and the TPMS has been good after resetting each time.

 

mine's been behaving and is not overly sensitive.

When I had one new tyre on the front after a non-repairable puncture, the tyre pressure warning went off regularly. It seems that the system doesn't handle 8mm nsf and 4mm osf very well.
