Does anyone know the correct original factory stock rear rim and tire size for the 1951 model Z row crop tractor with narrow front end? I've been told that they came stock with 13.6x38 rear tires. I can't find anything to back that up.
 
I am thinking more like 11-38 rims and the modern tire size is 12.9-38. I am sure both the ZBs here are running 12.9-38 tires and the ZB model replaced the ZT.

I am thinking the 13.9-38 tire was correct for some of the UT and UB tractors.
 
11.2 was the 10, 12.4 was the 11 and that was orignal size, 13.6 would be equal to the 12 that would be an oversize but a lot were converted. And there are no 13.9 tires, that number is 13.6, flip the 9 over to get it correct.
 
See above specs from an original ZA brochure. The rear rims were 10x38 and the tire size was 11-38, equivalent to a 12.4-38 in the newer tire sizes.

You right on the sizes, but I got a suprise a few years ago, I bought a 13.9 X36 tire new at a auction. My 335 had a 13.6 and a 13.9 on it when I got it.
