I would like to buy another set of drive tires for my F2690 front deck mower to use on the hills during the wet season. The tire spec says I need a 12" x 9.5" 5 hole wheel. I'm not having any luck finding where to buy wheels. My F2690 has 12" x 8.5" 5 hole on it now. If I could find another set of these I could make it work also. I went to my Kubota dealer and his parts book said to get them locally. Sounds simple but I spent a couple of hours on the internet looking and I'm coming up with zero. Where do you find a decent selection of Kubota wheels for sale? Thanks for your help
