Having worked in tire shops in Southeasten Ohio for a few years , quite a few, I have seen so many tires have to be cut out from underneath of pickups , all of you saying its great wait a couple of years and see how they are. As far as mounting it on the back several have done it over the years look at older broncos etc all had a tire mounted on a tire swing off the side,
