Tractor tires I use to workout. I have 3 but am only taking 2 when I move. You can use them to flip, pull, push, leg press, do step ups, squats, push ups, dips, plyo! Use it as a play pin for your toddler while you're getting your sweet on! Yep I did it, I'm a redneck! Haha Anyway, someone who will use the other 2 more should definitely take advantage of them. Text is best. I'd like to get rid of them sat so I don't have to move them!
