Tyre Preasure

[goodheart23]

HI All

 

Can someone advise me on my tyre pressures, I have a Auto trail Delaware the hand book from auto trail says that front and back should be 55bar or 79 psi the tyres are continental van camper make, on the tyres the pressures state 4.75 bar or 69 psi would anyone be so kind as to which pressure I should take notice of.

Hi Goodheart, if you know your axle weights when in use, you can email continental and they'll send you a chart of load versus tyre pressure,

Search here, there must be a 100 references.

Oops, 55 bar is 770 lbs/sq in so it should be 5.5 bar. Do a search and you will get the correct figure.

Having problems. Apologies for multiple postings

Continental will approve your Delaware's "Vanco Camper" tyres being inflated to 5.5bar. On that basis, you should follow the Auto-Trail handbook's recommendation.

If you want to confirm this, download this Continental technical handbook:

You haven't said what size of Vanco-Camper your Delaware has, but I expect it's 225/75 R16CP. If you print off Pages 24 & 25 of the handbook, line them up alongside each other and read the Vanco-Camper data across, you'll see 4.75bar/69psi is advised for front wheels, but 5.5bar/80psi for rear wheels.

 

I'm not going to comment on whether or not 4.75bar, 5.5bar, or some other pressure would be 'right' for your Delaware; I'm just highlighting that Continental does approve/recommend Vanco-Camper tyres being inflated well above their side-wall marking.

thanks for all your help, after looking at continental data, I shall have my tyres at front 69 psi rear 80psi my tyres are 225/75 R 16cp.

just to let you know the front were inflated to 72 psi rear 78 psi spare wheel was 69 psi I have now inflated spare to 80 psi I have a digital tyre gauge so if I have a puncture in the front I can deflate to 69 psi.
