If the pressures are OK, just run a reset through the dash control and it'll be fine. Happens most times I change alloys and forget to recalibrate too.

How do I do that mate

It tells you in the manual...!

Essentially you turn ignition on, scroll up/down using the left stalk until you see the tyre reset option, then hold the button on the end down for 3 secs and it will put a tick on the display. When you start and drive off, it'll calibrate the TPS to your current tyres.

A little concerned you have decided 32 psi is the setting, as I'm not aware of any M-sport wheel set which suggests 32 psi as the figure on all four wheels.

What size rims and tyre sizes have you got fitted?

I agree. The car will handle very badly with the tyres underinflated

i had this happen a few times but i reset it, after a few times of getting out and kicking the tyres and looking for nails it looked fine, but it went down to 20psi well thats what the garage said and i just come back from a 300mile trip lol, so he pumped up the tyre again and stuck it into a bath to see where the air was coming from,and it was coming from the rim of the tyre,as the tyre was fitted that week they must of not put it on right or pumped it up enough to seal it, when they got it off the sidewalls inside where like world war 3 has gone off, there fault i had a new tyre

I got 18inches on...I like them hard! ;-) 38psi front and 40psi rear!...

I think anything between 36 and 42 will be ok...
