    Can anyone tell me what the tyre pressures should be?

    The car has been stuck in the garage over winter and it's now showing a low pressure warning. Can't find the service manual.

    Look at the sticker in the door jam.
    Around 32 psi I think.

    Cool. Didn't think of that.

    2.2 bar for both front and rear.

    Thanks for your help

    Mine says Front 35, Rear 32 ... it is raining and I got wet checking it out in the parking lot at work. FYI the car does a bit of understeer with this pressure setup. If they are both set to the same pressure the understeer goes away so I set mine to 34 all the way around. On the track I cut that back to 32 all the way around cold.

    Thanks for the info Rick. Mine says 32 all round.

    Hope you don't catch a cold on my part!

    If you go to this website, you can download an owners manual and put it on your computer hard drive. Then you can look things up without having to have access to the car. Looks like all the tires except the 20" Bridgestones recommend, in the owners manual, 35/32 (2.4/2.2 bars) and those are 32/32 (2.2/2.2 bars). The data plate still has priority because tires change and the OM will likely not be updated until the M appears.
