    Hope this is the correct area. Got an odd question I have wondered about. Proper placement of different tread types on tandems. We have several trucks where the tread types are all mixed up on tandems. One truck has all mud & snows on one side, the other side is all steer and/or trailer tires. The tread depth is near equal on all tires.
    Would it be best to arrange the tire different?
    Would mud and snows be better if on the back drives, 2 on each side, with the straight tires on the front drives, 2 on each side? Or vise versa? TIA

    I would recommend trying to get all the drive “lug” patterns across all 4 on the same axle. Put all the steer “ribbed” patterns together across the other. Probably best to put the lugs on the front diff in this case.

    Doesn't really matter as far as traction I don't think. The 1 of 4 wheel ends with the least traction will always spin first

    I can finally use my grandpa’s wisdom. He always said the rear drive provides the most power so your luggy tires on the rear and your nice road tires on the front. Can atest to this since my T880 still has the factory Michilen-XDN2 on the front drive axle and the rears have long been chewed up.

    The rears wear faster due to scuffing when they swing during turns. The truck pivots on front drives. That is why when the power divider is locked in turning radius increases because now the rears are trying to pivot instead of scuffing. The front diff does most of the work. Need proof. Remove the interaxle shaft between diffs and lock the power divider in. The truck will still move. Not the other way around.

    I would contact National Tire and Battery customer service on this website and ask them this question.
    Those guys are gods when it comes to tires. There was no questions which they couldn't answer in the past. Hope it helps.

    I run the higher traction luggers on rear axle, old steers on the front axle. Works for me.
