Elddis autoquest 196 tyre pressure
Can anybody advise the correct tyre pressure for my Peugeot/Elddis Autoquest 196.
The elddis manual recomends running 72 psi (front) and 79 psi (rear) but today on a “A” road it Felt as if the pressures were too hard.

If it felt too hard, I'd reduce them a bit and see how it feels.
Have you got the Peugeot adjustable air suspension? If so, try softening that.

You can use the 'TyreSafe Motorhome Tyre Inflation Pressure Advice' to find what pressures they advise or email your tyre manufacturer direct.
You need to know the front and rear axle weights (around £5 to use a local weighbridge) and the size and type of tyres you have.
A few clicks on their advice chart and you get the recommended pressures.
With the tyres I have fitted (225/70 R 15C 112/110) on my Pilote and with front axle 1560kg and rear axle 1940kg confirmed fully laden by a weighbridge the recommended pressures are 47psi front and 61psi rear.
Use a weighbridge, not only to find the axle weights, but also to find if you are overloaded and therefore illegal - we don't want to get on the naughty step, do we?

again as with the informative post above..
for those interested in getting the correct tyre pressures for 'their' van rather than the generic Ducato defaults of 'rock hard', the two main camper tyre companies, Michelin and Continental are both happy to supply info either by phone/email or by making their charts available...but you must specify the exact tyre size, model etc.
i emailed Continental following a visit to a weighbridge and got the following data reply,
as earlier comments, it does show how much lower (read 'more comfortable') the correct pressures are...
weigh van fully loaded (incl wine allowance)
- 3420 kg, front 1600 (max 1850), rear 1820 (max 2000)
Continental tyre pressures as follows.....
Front Axle: 1600 Kg - 3.0 bar/ 43.5 psi
Rear Axle: 1820 Kg - 3.75 bar/ 54.3 psi0 -
Just found this on another forum after BoleroBoy advice on contacting continental tyres.
This shows I am running with over inflated tyres. Running at max axle weights shows front 58psi and rear 68 psi
See below from another forum
Rear axle 1900kg (max 2000)
Front axle 1540kg (max 1850)
Gross 3440 kg (max 3500)
The following is the reply from Craig, the Product Support Engineer of Continental Automobil. He has consented to having his reply published on MHF:
The pressures you require are as follows:
Front: 3.25bar - 47psi pressure applicable to a maximum permissible load of1590kg. 1850kg Max loading at 4bar - 58psi (1875kg maximum at this pressure)
Rear: 4.25bar - 61psi pressure applicable to a maximum permissible load of1970kg. 2000kg Max loading at 4.5bar - 65psi (2060kg maximum at this pressure)
As a general rule for pressures on this tyre, every 100kg added from the base figure of 1490kg at 3bar (43.5psi) will require an increase of 0.25bar(3.6psi) in pressure up to a maximum of 2060kg at 4.5bar (65psi)0 -
I visited the local weighbridge (free of charge if you don’t need an official ticket). 1500kg front1940kg rear so I emailed Continental who gave me the exact tyre pressure front and rear. Front at 47psi was significantly less than the figures stamped inside the nearside door the Peugeot cab and much less than I was running at. BUT, if I reduce the front pressures the low pressure warning will come up on the dashboard and the level cannot be reset except by a Peugeot dealer at a cost.
Havent decided what to do yet.

Hi hitchglitch, I was thinking the same about the under pressure warning light. My Peugeot cab also shows 72 psi front and 79 psi rear but as mentioned this is far too hard of a ride.
Have you any idea what the tpm lower setting level is set at when the warning light comes on?

Unfortunately it’s around 4.5/5 bar. Can’t remember the exact figure but you will soon find out if you reduce the pressure. I am going to try it out on a trip in a week’s time and see if I can live with the warning signal. I have the Ring tyre compressor so it will be easy to reinflate after the trip if needed. The Peugeot is due for a service after the winter so will also check with the dealer.
By the way, I have an Autosleeper and the factory and dealers don’t seem to have a clue about tyre pressures. They go by what’s printed on the plate in the cab which is a Peugeot plate, not Autosleeper. However, is is only fair to say that they don’t know what load you are operating at so you need to go through all the steps - weighbridge then tyre advice.

All these pressures in the 70's are maximum for the tyres! We gave our plated weights to the Michelin help line back in 2005, and they advised us to use 60 front and 65 rear. When we changed to Continental, they agreed the figures. Now approaching 160,000 miles, we've had good wear ( circa 40k miles ) out of our tyres and trouble-free handling.

Not managed to get to a weighbridge yet but reduced tyre pressures to 60 front 68 rear from 72/79 and wow what a difference , no more thuds when on bumpy road and much better hurl 😀. Once I’ve been to the weighbridge I adjust again.
Not sure what he tyre pressure warnings lights comes on, but all right at 60/68.

Quite a conundrum tyre pressures. I find it confusing and surprised manufacturers appear simply to offer up the maximum for the benefit of doubt I guess!
My 2018 Elddis accordo 135 indicates the same pressures as the much larger sibling Autoquest 185 for example, the Accordo with a 3300 Kg chassis and latterly 3500 Kg in the case of the Autoquest! So why would you expect the lower specification chassis to have an identical seemingly exaggerated pressure, the ride is awful in my view!
Whilst I haven't ventured to the weighbridge as yet, I'm more concerned should I reduce/experiment with lower pressures how will the law view the matter?
I suspect a few lbs won't matter, as my van includes calibrated TPS, I may well find my efforts thwarted in any event.....
I'm surprised a standard isn't in place for what is a very important matter, rant over.......

The TPMS on my Majestic nags incessantly unless the tyres are at rock hard pressures. Recalibration is, I understand, expensive and also likely to cause consternation at Peugeot dealers as there seems little documentation on the issue.
