All right I want your take on this. I have a 39 RC that has 24s on the back and this tractor is original. All evidence I can find is that these tractors had 28.

My understanding was they had 24s, cheaper and with less power was all that was needed.

Take a look at Tom's info here from a price book. Down about 7 lines it shows 28" as an option over the standard rubber rear tire.

I've never seen a RC with 24" rears. My book say's 10-28 rear tires (old type number)

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.

The 24 in rears are probably from an early WC. Same chassis as RC except rear axle ratio.

They would bolt right on.

Not sayin they might not have offered 24's, but I've never seen any. Nebraska Test was done on 10 x 28's.

I have an unstyled WC on Steel that I would happily put these wheels on. I guess I really don't care but something made me just look twice being no styled anything ever had 24s that I recall. AI States there are some early ones that may have had 24s. I guess if I could find some complete 28 assemblies I bolt them on. Anybody got some?

Phil that's what I thought too but it had to have been done a long damn time ago. This tractor's been in my life for 25 years. It looks like they've been on there it's whole life. Wondering maybe a dealer swap. Honestly I don't even know what made me think twice other than the rear tires are 14.9. Awful wide
