    Hi

    I cannot find on the tractor tyres the recommended psi to pump the following tyres.

    Front tyres r24 380/70
    Rear r34 480/70

    What pressure bar/psi would be enough for these tyres?

    It all really depends on what work the tractor is doing - you'll have different pressures for field work/ploughing etc than you would have for road work. Lower for field work, higher for the road/towing loads.

    Looking at the tyre sizes I'm assuming it's a small-mid size tractor doing mostly yard work, so around 18-20psi would be a good starting point. You generally want to have 3 lugs of the tyre in contact with the ground, so adjust until you hit that spot.

    It can vary a lot, depending on what kind of weight you intend carrying. Is there a front loader?

    For general use, with no loader 22 - 24 psi should be grand

    No front loader. Just for drawing bales off field and to farmyard which is about a 1km trek on the road.

    You'd want 24psi carrying bales on the road. Maybe 26 if the bales are very heavy. Just make sure that the tyres aren't bulging out too much at the bottom when the weight is on them...
