    What tyre pressure do you run your motorhome on? Given that in theory the precise optimum pressure should be dictated by the actual axle weights, do any of you go to that trouble? Do you just inflate as per the handbook for ride comfort or optimum wear or do you have another method?

    Some examples of weight and inflation would be helpful, thanks

    I run at the tyre recommendation of 80 psi, we got over 50,000 miles from tyres before we had to change them.

    Is that 80psi all round?

    yep all four (I should check the spare while we're on the subject)

    Motorhome Tyre Pressures? This is getting as bad as the gassing and A-frame threads! :Doh:

    I stuck mine on a weighbridge to get both axle weights, emailed Continental and then adjusted their pressures a little downwards to get my preferred pressures.

    My max weights are 1880kg front/ 2000 rear and pressures 62/79psi

    My loads actual loads are 1380/1820* (although I've shifted a bit more to the front since)

    Continental recommended 45/72

    I use 55/70psi and the air rides are set at 3bar.

    * No wonder I get stuck on damp grass :RollEyes:

    I too did the weigh bridge thing and run all mine at 68psi as recommended by the tyre manufacturer for that weight :thumb:

    Probably, but a little more important to get right:BigGrin:

    60psi front & 80psi rear......figures obtained from Michelin customer care having provided them with axle weights from weighbridege.

    75 on the back and 70 on the front. It feels right when they are at those pressures and there doesn't seem to be any excessive or unequal wear.

    I run at the handbook recommended presure for the 1992 Hymer S700.

    Front 3.25bar (47psi) - weighbridge load 1540kg - max in handbook 1700kg
    Rear 4.5bar (65psi) - weighbridge load 2840kg - max in handbook 3200kg (Twin wheels on back)

    I run mine at 65 psi based on the recommendation of the tyre company who I get to inflate my tyres before each journey.
    Interested on any thoughts.

    I run mine as stated in the handbook as 55 in the front and 64 in the back. It is a panel van conversion on a Renault master. Should I be weighing first?
    As a matter of interest they are on alloy wheels and lose pressure quite a bit.

    I had this on a not very old car recently. Sounds like you're losing the seal around the rim, I was told a build up aluminium oxide inside the wheel is a common problem especially when they're ageing.

    My Autotrail Handbook refers you to the Fiat Handbook and then the cab label which specifically refers to the Camper tyres fitted. Pressures are 79.5psi or 5.5 bar all round. Max axles weights are similar for front and rear, 2100 and 2400. Ride is firm but well controlled, probably helped by the Alko chassis.
    I never ever use garage pumps on any vehicle, they're so unreliable.
    The biggest problem that I've had is achieving the correct pressure and still having it once I've disconnected the compressor :Angry:
    I still carry the compressor supplied, because it has a built-in gunge tank fitted for emergency puncture repairs but, I also have a spare wheel :thumb: But this compressor has a hard to read (accurately) analogue gauge and one of those stupid clip on valve connectors. As a result you lose pressure putting it on and sometimes even more taking it off.
    I now use a Michelin 12V Rapid Digital Tyre Inflator with Auto Cut Off which claims to be accurate +/- 1psi up to 50psi, but seems just as good to me at 80psi. The lights and auto cut-off are great but, most of all it has a screw valve connector and you soon master the push/pull technique for minimising pressure loss while fitting. :Wink:

    What pressures would you recommend for a tag axle 4.5 tonner ?.

    interesting thread i have been experimenting with the tyre pressures on our autotrail cherokee on the fiat maxi camper chassis 4250 gvw.

    As already stated in previous thread recommended pressure by fiat is 5.5 bar front and rear in my opinion this gives a very hard ride and makes the steering feel very light and skitish on accelleration.

    I tried 4.5 bar front and rear good ride but rolled a bit on corners:Eeek: and felt suseptable to cross winds.

    Now running at 5 bar front and rear at moment which seems a good compromise and definatley easier on the fillings.

    NB this is only an opinion not advice
