Tyre pressures

Recommended Posts

Hi all.

I recently bought a 56 plate 1.4 mini cooper for my wife.

She absolutely loves the car.

However the tyre pressure light came on today and the tyre pressures are correct as they are printed inside the driver's  door jam.

Have tried looking up the tyre pressure on various tyre site like national tyres etc and they all say the car originally had a different tyre size

The ones on the car say 205/45 zr17.

Does anyone know what the correct pressure for these are?

Thanks in advance for any help.

Welcome to the Forum

My neighbours Mini is sitting on 7x17 inch wheels with the same size tyres as yours she has them at 34psi 

The tyre pressure monitoring system could have a fault with one wheel. Not sure which system your Mini runs if your car has a metal tyre valve stem it could be a fail of that sensor not that expensive (available on several Auction sites. The pain obviously is the tyre has to be removed to change it. I believe early cars used the ABS sensors checking wheel rotation at each corner. 

A scan should be able to tell what the fault is or you could try disconnecting the battery for around 30 mins (Neg first ) to see if that resets things

Good Luck
