I told Revain I no longer need to write reviews but I'm about to break my rule on these. I love them and the reason is that they have to patent the tread design. I'm no engineer but this model is great and they should make them big enough for Kubota 23x10.50-12. The traditional tread pattern on the outside of the lugs is the result of protecting the tuff from the lugs, which provide the best traction in tight corners. So one helps the other. I called and spoke to the smart cookie and asked them to make them bigger so if you need help they have real Americans who can help you too. win victory.
