Sam: I have no experience with Galaxy's, however I'd look for a 24" tire with 19 or 20 treads each side around the circumference of the tire. On those small wheels you will get better traction. My Super A has 15 year old, 9.5x24 Generals with 21 treads around the circumference. My 140 has 12.4x24 Firestone Field and Road and 16 treads around the circumference. My 130 has a mix, both 12.4x24, however the Astro has 20 treads and a Polish tire has 16 treads. On hard ground my Super A with no weight, liquid or solid will give the other two with wheel weights a hard run on a drawbar pull. That changes if flotation is a factor. That Astro tire has excellent traction, and is roughly 25 years old with not any weather checking. The Firestones have only been on my 140 roughly 6 months. During plowing, disking and field cultivator work, I can visably see those tires slipping in loose soil. The treads on those Firestones are chewed far worse than the older tires on the other two tractors. I wont comment on the Polish tire on 130 as it's only been on there two years and during that time has not seen a lot of heavy drawbar work, but the Astro has. When using the 130 in heavy pulling the 16 tread Polish tire will spin far quicker than the 20 tread Astro. Personally, I'll never put anything but 9.5 on my Super A. The C-113 engine is loaded with that. I'll go larger with C-123. My advice is count those treads, very important on those small circumference tires. 38" is a whole different ball game.
