I have a F2560 with a 72” deck. It’s a wonderful machine. But the two small gauge wheel tires on the front are frustrating. The stems are buried into the wheel, and are really hard to access. now one tire has a slow leak. BTW, they are tube type. Needless to say I can simply take it off and put in a new tube, but they still need checking. I cannot understand why Kubota didn’t go with a solid tire for that application. I looked a little into foam filling them, but there are definitely some varied opinions on that process. Anyone with a suggestion, besides simple tube replacement? Thanks.
