If you have a look at the attached you should get the correct pressure. I carry a copy in the van at all times.From memory I'm running at about 4.0 to 4.2 for my Feeling loaded to 1350kg.

Wow Mat and Motters. That's huge difference. 42psi (3 bar) v 58psi (4bar).

Just for the record, I carry 3 bar in my 1000kg Troll with 13" wheels. Just remember too that the tyre pressures are part of the suspension on an Eriba. Don't go overboard with the inflation and be aware of your tyre's max pressure rating. It's displayed on there somewhere (normally on the inner wall).

Mat, the question of tyre pressures and tyre types on Eriba's will go on forever. The problem is several fold. Early vans were lightweight whilst newer vans are a lot heavier. Add in some vans can and do run happily on car tyres whilst others need commercial tyres and it can get really confusing.
My advice would be raise the pressure to about 50psi, get your loading correct with a noseweight of about 60kg and see how everything feels. Use this as your starting point to tweek things.
