Hi there. I hope someone can help me. We had new tyres put on our Bailey Wyoming 2008 series 6 twin axle caravan before we picked it up. I noticed the plate by the door had the printed PSI of 29 crossed out and had 50 PSI written in pen, this has now washed off so I'm presuming the tyre fitter wrote this. I've checked the service book and this also says 29 PSI so today I've taken some air out of each tyre down to 29 PSI. Have I done the right thing?????? The tyres are 185/65R14 93N M&S 'radial tubeless for trailer use only'.
Thanks

The service book says 29 PSI and so does the outside weight plate. Hoping it's just a numpty tyre fitter.

Sounds about right. We have a Bailey twin axle and ours is 34. Don't need to be so high on twins.

For future ref you probably don't need van tyres as you've 4 touching the road, ours is on car tyres but do check the weight of your van.

Is there a maximum pressure listed on the tyre. By working out the weight on each and the maximum loading you can work out the pressure.

Depends on the Maximum permissable axle or vehicle weight your caravan has .
then I am able to calculate it with spreadsheet I made.
Then I will first lower the Loadindex of your N speedrated tyres , to give them same deflection a Q speedrated tyre would have
And also add a reserve of 11% to the axle load , and then still no bumping, and maximum reserve .
This will mean a higer advice pressure then the 29 psi , but still lower then the 55 psi the tire needs for the maximum load of 650kg up to 140km/87m/h.
Calculated roughly that the caravan maker calculated the 29 psi for about 1500 kg MPVW.
But can be lower if original tyres where not 6Pr as I googled, but normal car tyre with AT-pressure of 36 psi for LI 86 = 530 kg a tyre.
Ok MPVW then 1700 kg so even higher.
The lower the AT-pressure the more loadcapacity at the same pressure .

29 sounds about right for a twin axle, not sure what my handbook says but i put a max of 35 in my twin.

Look on the tyre wall and see what us the maximum pressure. Looking in the handbook is all very well but different tyres may have been fitted.

Some vans are fitted with van tyres some with car tyres and the pressures could be around 30psi or over 60. Need to be sure.

being as caravan suspension systems are very basic its not a good idea to put more pressure in the tyres than the pressure that is needed.. the weight the tyre has to carry governs the pressure it needs to be at..

blowing the tyres up too hard will simply help rattle the caravan to pieces and bounce everything inside around more.. it will also cause the tyre to wear more in the middle and not evenly and put less rubber on the road..

the reading on the side of the tyre is simply a maximum pressure the tyre can be inflated to.. not the pressure the tyre needs to be inflated to..

plus from legal point of view its just as wrong to over inflate a tyre as it is to under inflate it..

Why am I a numpty owner Trog100? I wasn't the one adding the air into the tyres when they were fitted. If I was a tyre fitter then I would've fitted them myself! I was only asking for advice, thought that was what this forum was for!!!

you suggested a tyre fitter being the numpty i guessed at a previous owner.. you were talking about someone writing a figure different than the manual.. it should be quite clear that the someone wasnt you..

i quote my post..

"The service book says 29 PSI and so does the outside weight plate. Hoping it's just a numpty tyre fitter."

more like a numpty owner.. why blame a tyre fitter.. :) "

and said with smile.. no need to be so touchy.. :)

Trog100. The previous owner is a great mate of ours, he got new tyres sorted for us and the tyre fitter changed the weight plate with his idea of correct air consumption. As I am a 'lady of leisure' who lives a quiet life in the country I come onto these forums for advice from other friendly caravaners and don't worry I didn't get 'touchy'!!!

As long as topicstarter have not given some weights , and enaugh is Maximum permissable vehicle weight, and is given on the VIN plate that also has to be on caravans, I can not calculate a maximum pressure at wich no bumping, and a lowest pressure at wich the tyres wont damage at 120km/75m/h.
Then after that you can draw conclusions of what is done with that 29 crossed and 50 written.

Also need the exact tyre data so maximum load, speedcode, and kind of tyre to detemine the AT-pressure
To give idea.
Normal car tyre AT-pressure 36psi/2.5bar
XL/reinforced/Extraload 42psi/2.9bar.
6PR (Plyrating) AT pressure 55psi/3.8 bar
C-load 50psi/3.4 bar
8PR 65psi/4.5bar exeptions 69/70psi/4.75/4.8 bar
D-load 65psi/4.5 bar
more not needed for European caravans.
