Tyre pressure?

[n428]

What tyre pressure should there be on the RIB trailer wheels?

It is a RM trailer with a 5m Torndao- total weight of the trailer + rib etc is approx 750-1000kg.

The tyres are new and are 175 R 13 .

First RIB so no idea really!

Thanks

i guess you need to know the exact weight on the axle to work out what the pressure should be, i wonder is tyre manufactures do load/pressure graphs?
i always run mine at the pressure the tyre load carrying is rated at. my thinking behind this there is less tyre flex hence less heating, therefore less chance of a blowout. i think its 36psi for my tyres.

my 4.8 comes in at under 650kg if I remember correctly. Have you had your rig on a weigh bridge?

No- havent had the rig on a weighbridge yet. On the list of things to do.

Only reason I assume it's heavier than average is due to internal fuel tank of 60l, a 50hp 4stroke yam on the back, twin jockey seats and a very substantial RM trailer with overbars the original owner used to carry dinghies on top.

Thanks for advice
