Tyre pressure for trailer

[CSYMolly]

I normally have mine at 2bar for towing Molly. Yesterday I took a friends horse out with Molly and only thought when I got back that I probably should have put more pressure in the tyres. So firstly is 2bars enough for one and what should I have for two horses?
Thanks

The Ifor's tend to have a sticker on the inside of the groom's door with the correct tyre pressure. Mine are at 4.5 bar and my car's rear tyres when it is fully loaded are at 2.8.
I would therefore think that perhaps 2 is a little low, but it will of course depend on the size of tyre. A local garage should be able to advise you of the correct bar for a particular tyre.

I am sure I looked before for the tyre pressure in the trailer but it had nothing. I don't think they will need 4.5 bar they are like normal car tyres but perhaps I should at least go up to 2.5. Thanks
