What size rear tires did the d-17 come with from the factory?
Where can I did the info?

Did they come with 18.4-34?
 
Up to serial number 42001, the std size was 13 x 28. After that, the size was 14.9 x 28. Rice versions could be purchased with up to 18 x 28. Other sizes were available. Mine has 16.9 x 28.
 
As opposed to old all D17s I or my family have ever owned have had 16.9x28 with one having 18.4x28. That would include about 12 D17 tractors in the family.

13x28 is the same as 14.9x28. Just updated to reflect a different measuring point on the tire.

Nebraska test shows 16.9x28 so all tractors sold in Nebraska must have 16.9x28 as standard equipment and anything else was optional.

16.9x28 also looks like a better fit for a D17.
 
The high crop version came with 13.6 x 38. All other tires were 28. A number of combine tires were of different sizes and fit the Allis hub. If the wheel is not a spin out wheel but rather a fixed rim, the wheels and tires may have come from a combine. There are quite a few WD-45's out there with these wheels but, they didn't come that way from the factory. When good tires are available on good rims, sometimes owners take them. Are the rims on this tractor spin out, Allis style? If they are, this would be an interesting project figuring where they came from. Perhaps a different tractor make.
 
13x28 and 14.9x28 are the same size tire- just old vs. new size marking. That was standard, but the oversize was 16.9x28. Old size marking would be a 15x28. Going from WC to WD to WD45 to D17..., oversize on the previous one was standard size on the next one. More hp needed more rubber on the ground.
 
They could be ordered with that size. I saw a brand new D-17 Diesel on a dealers lot in Wis in about 1959 with 34" tires. Only one I ever saw though.
