    Hi all,

    we have a 2002 Euramobil 770HB and I'm trying to find advice on what the tyre pressures should be for this vehicle.
    Theres an info plate for the normal (4 wheel) van, which says 79 psi front and back.
    Would this be relevant for a 4.5t tag axle motorhome?
    The tyre sizes are 215/75 x 16.
    Any advice gratefully received,

    Thanks

    Ignore the plate on the van. It's completely meaningless for a motorhome.

    The only place to get the correct pressures from is the tyre manufacturer.

    You need to email them with the details of the tyre including the weight rating and also the maximum and axle weights of the van. Actual weights are better but if you don't have those use the plated maximums.

    You don't say what tyres you have but if they are Michelin the email address to use is: michelin-contact@uk.michelin.com

    Wot he said!

    If you have Continental tyres the recommended pressures might be closer to 60psi, possibly a lot less on the rear as a tag axle is effectively the same as having double rear wheels.

    Not at home at the mo. and on my 'other' computer I have a crib sheet for the various tyre pressures to be applied to various types of tyres in certain circs.
    Apparently, it's all to do with the use, load, and construction of the tyres in question. ie camper tyres, van tyres etc.

    I've just had a trawl through this interweb thingy and found the below. It looks fairly??? comprehensive.
    Happy reading.

    I ran mine at the sticker pressure and it was bone sha kingly hard so I dropped them by increments to fifty front sixty rear but am now back to sixty all round.

    @NickNic Thanks for that Michelin email address. I tried emailing them a while ago buy it must have been the wrong one as they never replied.

    When I was doing the same exercise they replied pretty quickly. I think it was the next day or the day after.

    Hi @Bill and Shell
    We have a 2002 tag axle Hymer plated to 5000kgs
    We run at 60 psi all round on Michelin Agilis M+S and for 80 percent of time are loaded to about 4750kgs as we carry a 650cc motorbike in the garage.
    These pressures give a decent ride much softer than the higher pressures and we get good mileage from our tyres.
    Hope this helps(y)

    The link @emmitdb posted is what continental will send you a screen shot of once you send them your tyre pressures.
    If you're using continental tyres that link is all you need.

    Hi @Bill and Shell. :)

    We have 6 x commercial tyres all round, 215/75 x 16
    The fronts are Bridgestone Blizzak winter tyres inflated to 3.5bar.
    The rears are Barum Vanis tyres (Continental Group) inflated to 3.1bar.

    Both these pressures were advised by the manufacturers technical departments, based on the tyre size and maximum axle weights, ie, front @ 2000Kgs, and rear @ 1500Kgs (each).

    HTH,

    Jock. :)

    Hi Bill and Shell,

    Here is the extra info I had on file. When I applied the tyre pressures to our 'van working out the weights and the rating for our tyres (we are running on van tyres), I was told by some on here that the figures were low and we would lose economy but that hasn't been the case.

    Find your type of tyre in this list and get the calculator out;

    Safe travels,
    Derek

    @Bill and Shell Remember that the data in the links is only for Continental tyres.

    If yours are from any other manufacturer the pressures will be different.
