    Tyre Pressures - Astra Coupe turbo

    Hi,

    I just wanted to see what tyre pressures people use on their Astra Coupe Turbo.
    I have the standard turbo wheels and have been told to use 36F/33R

    Is that okay?

    Rik

    Tyre pressure is dependant on the weight of the car pushing down on the road rather than the size of the wheel/tyre, so you should be running the specified pressure for that model/engine.

    However sticking an extra one or two psi on larger rims won't do any harm (it's better than running too low).

    Yep, 36 front and 33 rear for normal usage (up to 3 passengers) and then up that to 39/45 when you've got the car full

    Running it on too low a pressure will mean that the tyres won't be helping to absorb bumps in the road, so more shock will be sent to the rims, and that will increase the chance of buckling them

    Try running them at 1 or 2 psi higher as this will give a bit more shock absorbancy in the tyres to keep it away from the rims. just experiment a bit and see which works best for you

    where's the wear on the tyres happening?

    on both outer edges?
    on one edge only?

    I was getting a very bad vibration through my wheels when going over 50, really felt like the steering wheel was gonna come free! Put it on ramp and 2 rears inside walls were cracked all the way round. Got 2 new tyres and prob was sorted. Just makin sure pressure is kept ok cos 2 19" tyres at crimbo isn't cheap!
