Ideal road tractor tyre pressures for towing a 30ft twin deck sheep box on low ex lorry trailer twin axel. Thanks

Depends a lot on tyre size and tractor weight

 

[Lincs Lass]

25psi should be ok all round

Yes you can't guess without knowing some basic facts

Find out static load radius ,when loaded and blow up or let down to it ,

No such thing unless running road orientated tyres such as roadbibs. 25psi all round be good for lower rolling resistance and fuel use but will wear middle out of cleats on tyres. Tractor tyres are designed to carry load at low pressure so it's a compromise between burning diesel or burning rubber.

25 too high 20 be plenty

I've always been told that 1,5 is the "go to" when you don't know/remember what that specific tyre calls for when roading.

How can anyone give you advice if you have not given tractor size, speed, tyre size, estimated weight on drawbar.

Size and make of tyre are key here, as is the means of weighing the machine. All the main tyre manufacturers publish tables of size, weight and load to determine the correct pressure.
