I just bought an M6800. I need to replace rear tires from turf to R1’s. How do I know or where can I confirm that rims are correct size on the rear tires? Thanks

I know all about ratio issues etc. the fronts are original specd size. Thanks

I'd try to find what you need here on Kubota's website: https://apps.kubotausa.com/illustrated-parts/

You know your tractor best and which model it is. To me it looks like all of the rear rim options are 15x30 to fit a factory spec tire.

If you don't have this size rim, then you'd have to consider buying them and whether or not the disks you have will mate up to the new rims...it looks quite costly to go to this size. Hopefully you have a 2WD model and someone was able to fit turf tires onto the original R1 wheels so you can just go back to the factory size R1 tire (16.9-30). Unfortunately, the information form Kubota contradicts that is on tractordata, here: http://www.tractordata.com/farm-tractors/001/3/2/1321-kubota-m6800-dimensions.html

Maybe you can find some part number on some of these pieces and figure out what happened in order to get your tractor some ag tires.
