sizes

My T30 (a panel van being converted to a camper) came with 20" wheels but I've decided to ditch them and go smaller - because (a) it's a camper so I don't wantto be constantly worrying about kerbing (b) the roads round my way are utterly awful for potholes and (c) tyres are a damn site cheaper...

Hi Guys, Don't know if anyone can help. I've just ordered a t5 swb van and need to order decals ready for it arriving. Would anyone be so kind as to give me the measurements of the full side panel where the side windows would be and the full width and height of where the rear windows would go...

Im thinking of getting some 16" Ronal R50 Aeros for my SWB T4.........problem is i do NOT want big fat tyres.........does anyone know what tyres i should get that maintain load rating but dont look mickey mouse?!?!? :*
