A different geometry and lug shape than the original. Subjectively looks more like real tractor tyres to me.

The OpenRC MK3 Tractor is a great model. Just about the only thing I didn't like on it though are the rear tyres. To me, they didn't quite have the look of “real” tyres.
I've printed them out of PLA.
These are printed in two pieces that you must glue together. I use Loctite 380 “Black Max” cyanoacrylate because I had it on hand but I figure any glue that will work with PLA would do.
20% grid infill seems to work ok.
There are four locating holes on the inner sides of each half. I've sized them so they print out at 6mm dia. on my printer. I used 12mm long bits of aluminium I turned to 6mm dia. on the lathe. There's no reason you couldn't print small cylinders to act as locating pins.
I've used "fuzzy skin" on the lugs to provide a bit of texture, looks decent enough, I think.
Edit: added a single piece tyre by request
