The tires are the tires no big surprise. The big deal to me is that I had a 20 year old tractor and Firestone had discontinued them and they were the only manufacturer. None of the Firestone agriculture dealers could get them. Lucky for me my local dealer told me about M. E. Miller. They not only had the tires in stock but had them to me in 2 days. Great service and the tires were very fairly priced.
