    When on a tandem axle tractor, is it ok if tires on one axle are brand new and on the other almost worn?
    What im trying to get as is the difference in tires on the two axles a problem? Or is it safe?

    It depends. If you're driving a Mack, and you've got Mack rears on it, then you need to keep all 4 corners about the same. If you're driving pretty much any other truck that has open differentials, then it doesn't really matter.

    I would place the 4 new on the rear rear axle and the 4 worn on the front axle so to make the worn tires last longer. I.e . The rear rear being your pulling axle from my own experience

    In general, the recomended maximum difference between front and rear drives is 10/32. Will a large difference be a problem. Not that I have been able to determine from people who run like that. Having a big difference in the side to side I think is more of a problem

    New tires on the rear axle tandem. Old tires on the forward tandem axle. Ideally no more than 8/32" difference in tread depth assuming tires are the same make and model.

    Thanks for the replies guys. Getting a truck from another guy and he has pretty much brand new lug tires on the back axle, half worn out on the front. You can notice theres a quite of a difference and was debating whether to replace the front axle or not. Seems like a waste of tires, so i think ill leave it for now if its not gonna be a problem
