There are usually three of us training and if it is not already standing up from the last flip...we all stand it up together. We then roll it back by the barn and lay it back down.
I am the only one of the three of my event partners that can get it past their knees. My buddy can easily deadlift 500lbs...and has a very hard time getting it more than a foot. He is 6'2", like me, and height helps with leverage I think.
I pray a lot before I do the tire...but not for sure God listens when earth mover tires and atlas stones are involved lol...
