Help me understand wheel options

[dbsoundman]

Hi all, I’m new to tractors, bringing an early 9N back to life so I can put it to work. Currently, it has 6x19(?) front tires and 11-28 rear tires. The front rims and tires are shot, but the centers are ok. Rear tires are splitting/dry rotting, so much so that the tube bulges out one of the holes, tires are filled with antifreeze, the rims don’t look great, but the centers look ok.

First of all, can I put 12.4-28 tires on my rims or do I need other rims? Trying to figure out if I have to stick with 11.2-28 or not. I’m also assuming that I can separate the rims from the centers but I wasn’t sure.

Second, would it be useful or wise to convert the rear end to 8N hubs? I wasn’t clear whether I had to replace the whole rear half of the tractor or if I could just do some portion of that. I know I’d still need 8 bolt centers but those seem more common.

Finally, are the 9N front rims adaptable to car tires like the 8N? Would that be advantageous?

I’ve searched for answers on all this but I’m just not clear on the answers. I can get pictures of my tractor tomorrow if needed.

Contact Tucker Tire in TN. They will ship tires on rims.

Yes you can change them out to 12.4. If rims are not rotted out on the inside you can use them again. If you have 6x19 tires they are oversized should 4x19 fronts. You can change your front hubs to 8n hubs then you’ll be able to run 16” rims/tires. It is possible to swap out the whole rear end to an 8n rear but you will need to figure out how to connect the the left brake pedal cause on the 8n it goes thru the trans housing. Might be possible to use the left brake pedal off you 9n but you might have to cut a keyway into the shaft. If you swap out the complete 8n rear you would also be adding position control

Ive got a Case VAC and 300 (similar size tractors and tires/wheels to your ford) The VAC had 11.2x28 rears and the 300 had 12.4x28 rears. I upgraded the 300 to 14.9x28 radials and would not go back now. The 12.4x28s then went down to the VAC. Both tractors sit taller now and have faster speeds because of the larger diameter from the ballooning of the tires width. The radials on the 300 bulge out at the bottoms and give it great traction for plowing. I would recommend trying to go for the 14.9x28 radials but they will be more expensive.

Am I misreading this?
14.9x28 tires on an N?
That's three sizes larger than recommended.
They would be comically big on an N.

You are probably right.

dbsound, where are you located? I have a set of NOS BKT 11.2 8 ply tires I would part with in Iowa.

I’m in Ohio, but please shoot me a PM, I might have a way to get them closer to me.
