Goodyear Optitrac DT824 600/70R28 tire for sale, was a rear tire on our combine. There are some weather cracks on one side and it slowly leaks some air. We were going to put some sealant on the inside but decided to put a new tire on. Would make a good spare or good main tire if sealant was applied to the inside. Lots of tread left, asking $200 OBO. Located near Mantador, ND. I'll help load it for you.
