    Hi all,I am thinking of changing the American wheels on my RV.
    Its a John Deere chassis,which is the forunner to the Oshkosh.
    Same size tyres, and the rims are the same 8R 19.5.
    As you all know this size is very difficult to obtain in Europe,so am thinking along the lines of a larger diameter wheel,with a lower profile tyre.
    I know that 225 75 19.5 will fit the rims,but they are as difficult to get in Europe as the originals.
    Does anyone know of a Euro truck wheel that will fit the John Deere-Oshkosh chassis,preferably on an older truck that I can obtain from the breakers,as I dont want to be buying a full set of new wheels and tyres.
    I would prefer larger diameter than at present,to help with fuel economy.

    hi Dave, sorry cant help with a supplier but are you sure about going bigger to improve economy.

    a bigger diameter will need more torque to turn it and as such will need more fuel.....especially on hills.

    bigger diameter wheel and lower profile tyre will balance out and wont make any difference to speed or economy.

    Hello John, No problem with the grunt,the old girl is low geared anyway.
    Would have liked a 2 speed axel,but am only dreaming with that one.
    Its these damned skinny rims that are making the problems.
    I tried 245 70 19.5 on them,but they were to wide for the rims.
    What I need is a standard Eurowheel and tyres.
    Have given myself a headache Googleing,and the US forums are not much help as they dont use Euro sizes or Euro trucks.

    Thanks for the reply, but I want to get away from the American size tyres, and onto Euro sizes.
    Thats why I need to change the rims.
    For years now I have been carting spare tyre casings on the roof in Europe and North Africa becouse the sizes are not availabe or like hens teeth outside the States.
    Once I have found out what size rim will fit the John Deere-Oshkosh chassis, I will have 10 yep 10 Michelin 8R 19.5 tyres for sale.:thumb:

    You could phone North Hants Tyres and speak to John Pettifor (The Boss). They will probably have all the answers on where you can get the NON American rims and tyres you wish to change too.

    Tyres......

    Hi.. hope you dont mind my asking.. have you sorted out your tyres as yet? we also have an Allegro, 32' Tiffin 1989 & she's needing a couple of tyres, did find a tyre supplier in Midlands & one up our way here in Cheshire but there are so pricey, was wondering if you still had any for sale & what condition they are in?

    thanks,
    Bev & Griff

    They are all part worn, the Goodyears are like new dated 2004, the Michelins are older but OK,plenty of tread left. You will never wear em out on your Tiffin.
    You can use them for steer or rear.PM me for my phone no.
