    OK we have a little trip to Padstow for four days........

    Will check the tyre pressures before setting off...On referring to Ford Manual its a nightmare working out what are the correct tyre pressures...

    To complicate further Ive heard complaints about the hard ride in the tranny
    when putting correct PSI's in...

    Can anybody help here?

    Cheers
    MM

    Tyre pressure in the Ford manyal will be wrong - that will be for an empty chassis - you need the converter manual.

    Or - get is weighed and get axle loading.

    Then call your tyre supplier tech support line and ask them.

    Every van is different based on ACTUAL tyre (differs by brand/type/loading/ply etc) and the pressure varies based on the above but especially axle loading.

    Tyre companies generally give info out free and are quite helpful!

    Dethleffs Sunlight low profile.

    OK its a 2.2 140HP front wheel drive.

    The manual says 50 front and 60 rear but I cannot be sure due to number of models quoted......

    The Ford is most certainly a harder ride than the Fiat chassis so I do not want to over pressure tyres and spoil ride. The positive is that the Ford is a much better drive than the Fiat!!

    I'm not looking for exact just an estimate for optimum ride..

    Activecampers is the definitive answer, go to your local weighbridge and get the weight on each axle with your normal running load. Get the full details off your tyres and email your tyre manufacturer. I had an answer from Continental the next day. Then you can adjust a little to suit the ride.

    My 2008 Burstner T620 is on a Transit chassis, 140bhp 2.2 Duratorq.
    Front and rear max axle weights are 1750kg and 2250kg.
    Tyres fitted are Continental Vanco 215/75R 16 C 113/111R.

    I emailed Continental and was advised 3.5bar/51psi on the front and 4.75bar/69pis rear.
    They were very helpful and even gave me a formula for working out pressures for lower than max loading.

    To quote 'As a general rule of thumb, every 105kg change will yield a difference of
    0.25 pressure based on the minimum loading of 1590kg @ 3.0bar (44psi) and
    the maximum loading of 2300kg @ 4.75bar (69psi).'


    Email address is Administrator.Technical@conti.de and the guy who replied to me was Craig Sterry.

    Hope this helps:Smile::Smile::Smile:
