I have 2 Kubota tires and rims. They came off a brand new B7800. They are 6 lug rims that I think are specific to the B7800. The size is 7-12 ( 180/85D12) .The tire is Bridgestone farm service lug -m.I am asking $ 200.00 plus shipping. If someone is interested I will find out how much shipping will be.
