806 Tires

I bought an 806 and it has 7:50-eighteen tires on the front and 34's on the back. I think 7:50 -sixteen was normal on front and 38's were normal on the rear. What would have been the advantages of this combination? Maybe a loader, and the 34's would slow the ground speed. Just curious. I plan to keep the 34's as they are in good condition and replace the 18's as they are very old. As always thanks in advance for your insight and replys.

18.4*38 only on the late ones many more had 18.4*34 rear tires

I have 10.00 X 16 on the front of my 806 and 856. Rear tires are 18.4 x 38 . I had another 806 that I sold last fall that had 18.4 X 34 rear and 10.00 X 16 on front also. Seen a few that had 11L X 15's on them. Just about all that I see around in my part of the country run 10.00 X 16 .

11L 15's on the front and 18.4 34 on back for me. I have put 16 on front and they look real odd like you are going up hill all the time. I have one with 16 rims on ft and 34 on back that needs new tires now. I am just putting 245 85 16 10 ply on it...will look better than tall 16 3 ribs. just my 2 scents

My gramps had an IH dealership in NY "back when", and when the 706/806's came out, there was an annual field day with a plowing demo with several makes, JD's, Allis, Ford, etc, and a 504 pulling 4, 706D pulling 5, 806D pulling 6, and a 4100 4WD pulling 8, just creamed those JD's LOL, like tractor "Shock & Awe". We kept the 706D demo and our potato-farming neighbor bought the 806D- both had 7.50-16/ 18.4-34 shoes on them when new, 706 had liquid and 4 sets of weights, 806 had liquid & 6 sets
BTW, both the 706 & 806 were turned up a bit (as were all the other tractors at the demo day LOL) and the 706D would pull 5 in L4 direct and the 806 was in the same gear with 6 behind, all 4 tractors came across the field in formation plowing down clover so fast that the dirt layed out flat enough that you couldn't see the individual furrows, just flat dirt. Gramps turned our 706 back down after the first season and swapped for a 4-bottom so he could plow at 3/4 throttle, which it would do, again, in L4 direct, just didn't like working it that hard, but that old 806 was still pulling that same 6-bottom the last time I saw it in 1977, and the engine had never been touched other than regular maintenance

I don't think there was such a thing as 18.4x38 when the 806 came out. It was "invented" some time during 806 production.

806 came stock with 18.4x34's and 7.50-16's. the 1206 was the first to have 18.4x38's on the rear, the 856 also had 18.4x38's.

The International 806 was standard with 7:50 x 18 front tires and the Farmall 806 was standard with 7:50 x 16 front tires. The standard rear tires on the Farmall 806 were 18.4 x 34 and late Farmall 806's had 18.4 x 38 as an option. Most International 806's in our area had 23.1 x 34 rear.

I would have never guessed a difference in International vs Farmall versions on the front. My 806 is a Farmall. It does set up a little in the front that is noticeable.
