I found the original thread.
This was my response when I found the rims:
I learned a hard lesson this week. I had my front tires loaded, I don't have an FEL, and I use a dirt scoop, so I need at the weight I can get on the front. I used my impact wrench, on my original OEM rims, that came on the tractors, and I cracked them all the way around the bolts. I brought it to have it welded, and they looked at it, and said that it was not worth the money, and would be difficult to weld. I searched very hard for a new rim,a nd the only one I could come up with is one from Yenebiz, and the shipping anlone is over $200 from Europe. I did alot more research, and finally I found that the rime from a Kubota
B7100,
B6100,
B5100 will fit perfectly, and the rims runs around $100. I had the dealer measure it, and it is a perfect match, and it even has the wheel weight holes that match up the same. I think that the rims are made by the same company in Japan for both Iseki and Kubota. I just need to paint it white when it gets here, and have the tire remounted. The part number for the tire is, 70000-00024. This site has it for $115, but I ordered it from a dealer because I wanted it to match exactly, and this rim has gaps on the inside. Anyways, i thought that you guys may be interested who have been looking for front rims. This is for the 5.00 by 12 rim size.
This is the company that I ordered them from, and below is the rim that I ordered:
Coleman Equipment - Case, Kubota, Stihl - Sales, Rental, Parts & Service
