Suggestions for Rear Tires for Farmall F-20

I have a 1937 Farmall F-20 with 36 inch F&H Spoke wheels. I am looking to put new tires on this tractor. The current tires, which I believe are original, are Firestone 11.25X36 Ground Grip. This tractor also has a mounted cultivator which I plan to leave installed.

My guestion is what make and model of tire would be suggested to use as a replacement ... which would the best tire to use and "look correct" for this tractor.

According to the tire charts I have read a 11.25X36 is equivalent to a 14.9X36 today. Looking at a modern tractor with 14.9 tires, I think they look to wide. Is this just an illusion or would mounting tires on the narrower F-20 rim pull the tire in far enough that they would look correct on the F-20?
 
I think a 13.6x36 is a good match. 12.4x36 might be a better fit on those rims , but 14.9x36 I don't think are made anymore and are awfully big on an F-20, I have a set on an F-30 with round spokes and they look ok on the bigger tractor but are pinched by the narrow rims and the tread is pretty rounded.
 
Do you have the 6 inch or 8 inch wide rim? if you have the narrow rims 11.2's fit good on them. If you have the 8 inch rims either a 12.4 or 13.6 will work. I personally think 12.4's look good on them
