Tractor tyre pressure?

[shea]

Guys i have a new holland 8560,which i bring a 4 tonne digger on the back of,i was just wondering what tyre pressure should be in front and rear tyres?
sizes are

Rear 650/65/r38
Front 540/65/r28

Any information would be great guys and thanks

More questions than answers here, all depends on what tyres they are? At a starting point I would go 18psi in the rear and 22psi in the front. But might have to inflate the rears carrying a lot of weight.

What type of trailer?

to set them correctly you need to know
tyre make
travel speed
axel load
as the there pressuere depend on this data

Oh it is single axle trailer

michelin on front,pirelli on rears

Where is the axle on the trailer, where do you park the digger on the trailer. All this and the above will determine the tyre pressure

14 front 16/18 rear will be fine for that and give you a bit better ride
