Can anyone enlighten me as to what the pressure should be in these tyres. Front 245/40 x18, rear 275/35 x 18 :?:

front 2.7/8 Kgm
back2.8/3.0 Kgm

depending on the speeds U will use above 200Km/h always 3.00

Thanks, it's a start point. There is no info available in the owners handbook regarding this tyre size, even though it must be a popular option.

The plot thickens !! :bounce:

Isnt there a sticker in your door jam with the different pressures?

The sticker only has the standard tyre/wheel size. I didn't ask the dealer thinking it would prob. be in handbook.

A simple rule of thumb is if you don't know, stick to the tyre pressures specified for the car. They are always going to be suporting the same load no mater the size.

And another one not in the handbook. Any clues as to what the pressures for the Pirelli P0 225/40 ZR18 should be (fitted on the current styling kit option).

Thanks
