For example: 20x10-8. What exactly do these numbers mean and do I
have to get the exact size that comes with my tractor or can I get a
tire that is not as wide? Thanks
20 inch outside diameter, 10 inches wide, on an 8 inch rim.

I don't think you mean DIAMETER.
It's width.
I was talking about the pre-metric sizing. A 20X10 /8 lawn and garden
tire was 20 inches TALL, and 10 inches WIDE and fit a 8 ing diameter
rim. The sidewalls were roughly 6 inches high

In automotive P-Metric terms they would be something like a P250/60-8
