Air suspention

[skids]

Can anyone give me a clue as to what pressure l should run on the gauge on my Hymer 650,its as l purchased it and no info with the van on it . What tyre pressures do you run as the van is not ever fully loaded ?

Hi I was in the same situation, bought my Benimar with air ride suspension but no idea what pressures to use but someone suggested 30psi and it seemed to be ok for my 3.5t rated van. Try it until you find what suits your loading. Simon

Best way to obtain information on tyre-pressures suitable for providing comfort with safety would be to measure your Hymer's individual axle-loads via a weighbridge then contact the manufacturer of your motorhome's tyres for advice. Any other method will involve guesswork and (however educated that might be) it won't be as satisfactory as 'horse's mouth' advice based on actual data. Regarding air-suspension pressures, you are really wasting your time fiddling with these until you've resolved the tyre-pressure issue. There is also the matter of whether your Hymer has 'genuine' air-suspension (ie air-bags that replace springs) or just Air-Ride-type spring assisters. You'd need to be miuch more careful about pressures with the former than the latter. If you've got spring assisters I suggest you start low (say 10psi) and then work up until you are satisfied with the 'feel' of the vehicle. If you've got full air-suspension then it would be wise to seek advice from a Hymer specialist or Hymer itself.

Hi There I run my 3850kg GMW Mirage at 56.5 psi front and 63.5 rear tyres, with 1.5 bar ( aprox 22psi ) in the Air rides I did run at a higher pressure on the air rides but found it too hard . hope this helps Mike
