Yes I got commercial tyres on the van as it was brand new when got it so the tyres were standard commercial also had the 2 back ones changed also commercial ... AS for tyre pressure I did put an extra 10 pound in them but still the tyres went out of shape as you can feel them when you run your hands round them !!!!! strange !!!!! cant wait to rid of it to be honest not the most comfortable ride the seats give me backache if driving on long journeys !!! Did have a traffic before this was a good van but anyone got the transporter and what are they like !!!
