Is there some truth to this?

[Jziemer]

The other day I was talking to a guy and he claims that if your
international tractor has bigger duals than the inside tire it will
turn on the headlands a lot easier and you will be able to pull
bigger equipment. Is there any truth to this?

No it is a great way to break axles.
On hard ground, the farther the contact wheels are from the steering tires, the wider the turn.
In soft ground, the wider the deepest penetration the more they try to turn the tractor despite where the front wheels are pointing. Jim

May turning easier 'empty',but would make no difference pulling a load.As Jim says"good way to break axles".If you have differing size tires,run the bigger inside,the smaller out.

Keep in mind that your inside tire is still supposed to be the main driving force. Never want the outer tire larger than inner. If tires are same size it is a good idea to run a few pounds less air in outside tire. I have seen way too many dual hubs give problems due to slightly over sized outer tire or over inflated or just a identical tire with more tread making it over sized.
 

[Jziemer]

Ok and I'm not 100% sure if he was talking about band duals or hub duals but I'm assuming that the same would be true for band duals?

Maybe some truth to it if your right side tires were larger than your left side tires and you were making left hand turns. That technically would make your right side tires the "outer tires" in the turning radius, however its feasability is non-existant.

Ok that's what I was kinda thinking to. I was wanting to buy duals for my 986 which has 18.4 38s and the duals he was trying to sell we're 20.4-38s and I figured I better get some more opinions on this

I guess the only reason I thought it would possibly work was I have seen tractors wit 20.8-38 tires inside and 18.4-38 tires as duals so I was thinking mane it would work with the 18.4-38 tires inside and the 20.8-38 as the duals. Thanks for the help
 

[Janicholson]

If the deal is incredible, why not swap the inner for the outer and be done with the issue?
 

[John B.]

If you have larger tires on one side than the other this will make your spider gears in you differential constantly walk even when driving in a straight line, because the smaller tires will be making more revolutions!

If you dont mind replacing broken axle bolts every other day. I am talking about the old type that clamp on the rim. You get too much pressure from that outer dual and you will break the bolt that hold the wheels to the axle. Least we did on our 706 and 766.

As long as the diameter is the same it doesn't matter where the wider tire is. But put a larger diameter tire outside of a smaller diameter hard parts will break.
