I am installing a set of duals on my MD for tilling traction and pulling wagons. (stability & traction). What is the minimum spacing between the two tires that I should have. Measured at the bottom of tire. I have 13.6 X 38 tires on now and that is also the size of my duals also. Thanks
Brad

Having them touching only provides one advantage. When you get into a soft spot and spin out, instead of going down, they mud builds up in the treads on the sides of the tires that are touching each other. They act like a big racing slick and you float instead of spinning in and it's easier to pull out. FOr a 13.6-38 tire snap-on or axle duals are about the same for difficulty, advantage going to snap-ons for not needing as precise an alignment. Duals aren't hard to work with till you get to 18.4-38's and then I can still mount them myself as long as I have a machine to stand them up with.

BRAD - Stick with the direct axle mount duals for Your MD. The old M & H cast rear wheels didn't like clamp-on duals. They tended to crack straight out from the clamps. Also as suggested keep dual tire pressure lower by 4-6 psi than the main tire. Using a much more worn tire than the main tractor tire works too. You will have no problem with traction with duals. On those smaller tractors You normally wonder where all the HP went!?!?

Brad, you can reduce the chance of axle breakage by running your outside dual at about 6 psi. On my big tractors I always ran 12-14 on the inside, 6-8 on the outside. Never broke an axle, the low pressure helps cushions the shock.

Brad: I wouldn't have them much closer than 4". My reasoning, ocasionally you get a stone or other object jambed between the tires, often times it can be removed with a bar. Sometimes it takes a chain around object and hooked to an anchor at other end. Awfully nice to be able to get your arm in there.

Wider may even be better but you have the trade off on total width of tractor. I've also heard when you space them too far, breakage becomes a factor. I didn't see this but have heard of big Farmalls and Deeres breaking axle between duals with them 1'+ apart This is with axle duals. I had 3 sets of duals all spaced about 4" and never had breakage. Just my experience.

Not being a farmer, I have to ask, What is wrong with having them touch? Rocks can't get stuck in between if they are touching, also can't you bolt them to the wheel bolts rather than the axles? (Like on a Cub) If my Cub had duals maybe it wouldn't turn over so easy.

R-cubed. I wouldn't bet a lot of my life savings on rocks not getting between duals even if they tight together. I've seen my tractors pickup square 10" rocks with duals only 4" apart. The other factor that will enter in with them tight together, they will chafe on each other.

I do know what will happen if objects are left between duals, it will destroy both tires. I expect the same would happen with them tight together, flexing of rubber as wheel turns would wear the side wall out, and do it rather quickly.

That was also my concern. Why can't they touch or have only a inch in between the two tires. In my opinion the axle mount duals are easier to mess with rather than any other way. Just my .02 cents worth.
