Yep - I thought tyres HAD to carry max. pressure rating.

Also see http://www.tyresafe.org/data/files/TyreSafeCaravan.pdf. I can't see your tyres (is 8-ply the same as "reinforced") but this table suggests rather lower pressure for (for example) my tyres - 175 x 13. I'm not sure of exact weight of my rig but guessing not more than 1200kg. So even at only 25psi the weight rating is 800kg/tyre, which is comfortable margin. Have to say I'm a bit confused now.

well i'm nearly embarrassed. I'll be busy removing the trailer spotting badge of my anorak (i clearly don't deserve it) as soon as I've finished this post.

50 psi on a coaster swing apparently it's a 10inch 6 ply

I used to have a trailer that ran on low-profile tyres that needed to be kept inflated to 95psi. If I let the pressure drop the tyres overheated quite quickly when trailing.
