Tractor Tire Size - is bigger always better? (width, diameter, aspect ratio)

Wider=less soil compaction, is pretty much always true. Ride quality; it might be worth looking at the recommended PSI for the tires. All things being equal, higher PSI =rougher ride.

I like today's 4wd tractors that have a lower aspect ratio in the front tires which makes sidewall stress and flexing much better (less) than older FEL designed tractors of which I have/had both excluding my 4010 and 4020 JDs with 9x or 11x (as I recall) width 8 ply tires.....the 9x on the 10 a little iffy as far as ground contacting support was concerned....with a full bucket on soft ground it sank more than I wanted......but what did you expect.....yes..........

Consider carefully, they last a long time (you’re kind of stuck with them. I would go wide and tall as possible. Keep an eye on the sidewall plies and load capacity for the fronts for loader work.
I like Trelleborgs and BKTs for good tires at a good price.

Wow, that was a long delay. i'm sorry about that. i thought I had replied earlier.

I chose these tires: MICHELIN BRAND R1W TIRES: REAR TIRES 520/85R38, FRONT TIRES 420/85R28

The tractor was ordered in Nov 2023 and I'm expecting delivery of it in late July 2024 (in a few weeks, I hope).

Thanks to each of you for taking the time to write and teach my about tire tradeoffs and preferences.

that looks like a good choice.
Ive seen a couple of dealer videos online that are ordering radials on the new tractors. It looks like a squarer profile on R1's and wider as well.
They should be somewhere between R1 and R4 on ride quality. R4 to me ride much better on rough ground but I hate that most manufacturers of tractor choose lower profile R4's.
Let us know how those tires you got do.
