550 Rim Replacement

My 550 has 26" rims. one of them is newer within the last 10 or so years. The other one is very rusty and has started leaking. It seems that most companies only sell 6 loop 28" rims for 550s, but no centers for 550s. The 26" rims are very expensive compared to 28"s. Tires seem to be about the same price for both 26" and 28". I can also find 28" rims locally cheaper, but then I'd still want correct 550 centers.

Would it be better for me to just buy one 26" rim and hope that I can get the tire switched over easy enough? Should I swap to 28" rims? What other tractors had the same bolt pattern as 550s? I've heard that for 8Ns and Allis Chalmers WD series tractors have the same bolt pattern, but I don't like the way those look.

I went through this and went to 28. Tires are more available so is rims. I was happy with it.

Thank you, that’s what I’m leaning towards at this time, but I have a hard time justifying that much money on a tractor that sees maybe 30 hours of work per year
 
My 26 rims was rotted out so no choice. Sold tires to guy with backhoe. Almost think ford and john deere rims would work as my new ones fit some john deere.

Good to know. One of the 26s I have is on borrowed time. It’s bad enough that I think it would have a good sized hole if I scraped away the flaking rust. That said, it’s been that way for probably 5 years or so.
 
Take some time and shop around I know prices are crazy. Many times when Demounting an old tire turns out rim is no good.

The tire being bad is my fear already, I have been pricing out tires too, just in case

I really needed mine to use was in good shape except tires. Could not see that 28 changed the speed any as I like the low gear

See I wouldn't mind a little bit more speed out of mine. I don't use low gear very often.
 
26" 6 loop rims were used on early combines. My 550 had badly rusted rims but real good tires. I found new 26" rims at a salvage yard that specializes in combine parts.
Some Ford, John Deere and several other brands used the 26" rims.
