Motorhome Weight

This is a reply given to a MHFacts member a few years ago - the weights are similar to yours, and also my MH, and I run the pressures as he advised -

'Last Sunday, I emailed Continental Tyres to ask what my tyre pressures should be. I offered the relevant tyre details... Fiat Ducato, X2/50, tyres information: 215/70 R 15 CP 109R

I included my axle weights which resulted from my last visit to a weighbridge... Yes, I do take my own advice!

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)

We do get a substantial amount of queries regarding pressures. Unfortunately, there is a distinct lack of understanding on the subject which isn't helped by the apparent reluctance of coach-builders to specify the pressures required. Naturally, all pressures are dependent on load so providing any queries received contain the information requested, we can advise accordingly. I've helped a few other organisers of motorhome/camping clubs and associations in the past so we are all working to educating the consumers as to what is required. Hopefully this will provide a greater understanding for them.'

well done, Hitch, got there in the end....what pressures did Continental recommend?

FYI, ive checked for TPMS on my van and, while the handbook shows various different instrument clusters, i cant see the warning light where it 'should be' if it was fitted.

perhaps we dont have it. either way, im not that bothered bearing in mind some of the 'unhelpful' comtributions ive read about from (especially) Peugeot....
