Easy and quick great service

I was looking for 16.9-24 tractor tires and the product code didn't say anything about 16.9 but did have other numbers that I hadn't seen. When I received the tires they were 8.3-24 which are a much smaller size. I have purchased the correct tires and just put the original tires in a FedEx Ground location this morning to return them. I searched for 16.9-24 when I found the site initially and was confused by the product numbers on the site. This is not necessarily your fault but if the product number had said 8.3 I wouldn't have purchased the wrong tires.

Package was shipped and delivery on time. Product looks top notch.
