I have to laugh at people that do this, put a single front tire on a dually....Obviously its a show truck that is never going to do a days work in its life, but, if you use it for what it's intended, you going to carry two spares??? One for the front and rear? In the real world, running down the interstate, I have ran over stuff dropped off of other rigs, and had front and rear flats on one side. What going to do then, sit and whine on the side of the road. Stupid
