Tractordata shows 6.00-12 tires for front wheels. Many other places Say 6-12. Kubota tech says there's no difference. Guy I bought the 6.00-12 tires from says they're 2 inches taller. I'm I stuck with tires I can't use? Is there someone out there with a B2150 that has the Ag tires that can look to see what size they have.
