I have been given conflicting advice regarding the correct tyre pressures. When I bought the van and collected it from the dealer. A swift Escape 622 2010 model, I was advised to put no more than 60 psi front and rear, and to ignore the plate in the van which says 79 psi front and rear. However, in the swift Motorhome handbook which came with the van it clearly says 79 psi all round. Can any owner of this van cast any light on the correct pressure.
