Hello , I was in Halfords and saw they had tyre pumps on offer , I thought about getting one but found they went up to max psi of 60, my wife said she thought the tyre's on our caravan , an Abbey Frestyle 540 which is a dealer special abbey vogue 495, were set higher than that, our van is in storage and with work I cannot make it easily and like an idiot, I left the book in the van, just wondered if anyone knows the tyre pressure on this van, thank you.
