Legal position on tyre pressures (1 Viewer)

[Mack100]

What tyre pressures you use seems to be whatever you fancy given the range of pressures there seem to be for my tyres.
I've consulted the manufacturer, Continental, noted the maximum load pressures advised by Fiat and looked at the information provided by TyreSafe.

For instance, according to Continental, if I load the front axle to 1500kg then the pressure should be at 50.7 psi.
When I took delivery of the motorhome 6 months ago the dealer had put 65 psi all round but seemed at a loss to explain how they arrived at this. Quite a difference in pressures!

My query is, what is the legal position if the motorhome were to be checked at the roadside or after an accident?

Legally.. If the tyres were inflated to a pressure well outside of the manufacturers recommendations and there is a suggestion that it could have played a part in an accident an insurance company may take it into account. For a roadside check there is going to be no comeback unless the tyres are obviously under or over inflated. It would have to be sufficient for it to be a dangerous condition.

Why is it not in the mot, then there would be no problem, whatever they said would be final:thumb:

My understanding is that the commercial arm use the maximum pressure for the benefit of "white van man/woman"...............fully loaded at the start of shift, decreasing load as the day progresses.

As we use our vehicles privately, the correct pressure for the rig should be used.

Its true, when we collected our Hymer, it was running at 70 psi..........a very hard ride.
After a trip to the weigh bridge, fully loaded, the ticket in hand, I contacted Michelin with:

Tyre size
Front axle weigh 1620 Kgs.
Rear axle weigh 2420 Kgs.

Reply was 65 psi on front and 50 psi rear, and they confirmed this in writing.

I consider we are compliant.

if you look on the wall of the conti tyres you will see "65psi max"! thats probably why. ( mine were the same ) however, Conti told me that this was only for the US market and should not be used for anywhere else. max permissible on the conti camper tyre is 5.5 bar or 80 psi.

i did as many have done weighed each axle fully loaded got pressures from manufacturer in email. " compliant " as far as i am concerned:thumb:

You seem to have some strange views on the scope of the MoT test
do I take it from your comment you check your pressures every year

Would you be happy if you had a fail because the tyre pressures were 4psi out because you checked them hot and they did the MOT when it was cold ?? How would they know what the weight of your Motor home was to know the correct pressure for that vehicle /tyre / weight loading . Best not to wish for something - you might get it

It's free so I always put plenty in

Thanks for the replies, looking at them I think I will stick to the Conti recommendations.

Generally a good choice. Get the max weight of the axle (who runs much less than max weight!?) and use the tyre manufacturers recommendation for that divided by the number of wheels. However, you might want to check the wheel manufacturer's max, too. Usually 80psi, but you can get outliers.

Unless you've got a dual rear wheel, they've accidentally swapped front and rear.

ask your insurer what they recommend, they are the ones with the get-out clause if the pressures are incorrect in an accident and their assesor must know to know they are incorrect.
But dont hold your breath waiting for a sensible reply..

Oh mystyc Bill have not seen Geos crystal balls the legal stance is you are the driver it's up to you to ensure your tyres are correctly inflated.........clearly written within the tyre law :thumb:

All the best Rick
