Trailer tyre pressures

[Chrissie]

Sorry - have also posted this under "vehicles", but need a fairly urgent reply.:

Can anyone tell me the tyre pressures in PSI preferably for a metal trailer 1m by 1m50 by 35cms deep?   Does 15 PSI sound anywhere near?

Thanks

You need to know the tyre dimensions.

It depends on the weight limit of the trailer, the load you intend to put in it and the size of the tyres. If you have the typical small wheels of this size of trailer then you probably have one of the following: spec from the Towsure web site

http://www.towsure.com/default.asp?t=60&p=0&d=28

"Trailer Wheel (400x8 /4ply Silver)
Tyre Specification - All tyres are "E" marked, have 4 stud fixing with 4" PCD.
3.50 x 8" 4 ply crossply tubeless tyre, Silver rim, Max load 170kg @ 2.5 BAR.
4.00 x 8" or 4.80 x 8" 4 ply crossply tubeless tyre, Silver or White rim, Max load 590lbs/268kg @ 60 PSI.
400 x 8" or 4.80 x 8" 6 ply crossply tube tyre, Silver or White rim, Max load 745lbs/339kg @ 90 PSI."

If you look at the marking on the tyres and they are 400x8 then the maximum pressure is usually marked on the sidewall.

My similar sized trailer is specified for a maximum load of 500kg and needs around the 60psi. Pumping up with a foot pump is a real chore!

You may have car sized tyres on your trailer in which case the pressures will be entirely different. If you look at the Towsure pages they will give you an idea of the pressures for different sized trailer wheels and loads.

Thanks to everyone for their replies, esp Alane and Sanjon.  I now have two nicely pumped tyres and know the max weight I can carry at what pressure.  Great.
