    One caution I would give is to avoid joins or seams in the roof if at all possible. I've had a number of leaks at the join in mine.
    If you know who will be building the box - ask them for advice on this.

    Hi Jostein
    Take two in inserting the pics. I have now driven more than 300 kms on the Michelin XZL 275/80R20 and very pleased. The handling issue described by IanC and I am familiar with on my previous Continentals LDR 10R17.5 have greatly reduced or disappeared. I had to do a minor cut-out on the wheel arch and sawing a piece off the bumper. I was lucky to find old Unimog wheels that fitted without alterations. If your planning to use your rig on rough terrain I would strongly recommend the XZL instead of the 285R19.5 truck tyres that most people seem to be using.

    Gretar,
    The Michelin XZL 275/80R20 tyre looks to have a load rating of 128 (1800Kg per tyre). Did you have to have the GVM of your Vario rear axle down rated from 5600kg?

    Those are nice tyres though. What's there overall diameter?

    Thank you for the pics Gretar, the wheels look good. The load rating on this tire are to low to get the car road legal without downrating rear axle load, but the use of old mog 20 inch rims opens up new possibilities. Do you know from what kind of mog they are? The diameter of 275/80R20 should be 948mm. About 37 inch. For comparsion the more widely used 285/70R19.5 are 895mm. 10R17.5 are 870mm. Rumours says that someone on Iceland are using 37x13.5R17 MT tires. Any info on that?

    Ian and Jostein
    My vehicle is now registered as a motorhome weighing approx. 5 tonnes. 37x13.5R17 are also used in Iceland and give a very comfortable ride.

    Nice and motivating pictures from Iceland! Some Day, when my truck is ready, I will go there.
    Can I Just ask where you get rims for the 37x13.5R17?

    The wheels 17 x 11.5 are made in Iceland. The rims come from the US but have to be widened and fitted with a new centre. I would be a little worried that these tyres dont last long in the lava fields. The XZL are 8 ply rating and should take the rough terrain better.
    Look forward to seeing you in Iceland. My plan is to visit Norway but have not got the dates yet, perhaps 2015. It is easy with the Smyril line but expensive.

    Gretar,
    You may have seen my thread here http://www.expeditionportal.com/foru...73#post1508973
    where I'm struggling with the handling of my camper with wider wheels. Do you have any directional stability problems with those wide tyres?
    I'm asking because I am having problems with the van not wanting to track in a straight line on poorly surfaced roads when I'm running on 285/70 19.5" tyres. The problem isn't noticeable wit the standard tyres fitted.

    Jostein - Apologies for the hijack of your thread

    I certainly had the stability problem you described on your thread on the 10R17.5 tyres. I have not experienced any problems after switching to the XZL tyres, BUT I have only done some 200 miles. The single fitment is causing this, but I think you could reduce the problem with a wider wheel. The wheel I am using now is 9" compared with 6.75" for the previous wheels. I guess your wheels are 8.25" ? and tyre 285mm so a lot of sideways movement is possible. Compared with my 275mm and 9" . What do you think??

    Now THAT's what was missing from the Vario! It finally looks correctly proportioned. Do you have to do a brake efficiency test to verifiy the truck can stop with the larger dimeter tyres?

    I'm guessing a U404 donated those wheels?
    Mine is probably bigger than yours.
    (isn't that what those long signatures are about?)
    I'm talking about my truck, what were you thinking? ;-)
