It used to break my heart, yet crack me up when I was running the Service Department at a Powersports Dealer... These guys go out and spend $60K-80K on a new top-of-the-line pickup truck, then spend another $12K-20K for a 8"-12" lift, big, wide off road tires, Flowmaster mufflers, etc. They would also buy a new dirt bike at the same time. Now these guys weren't the most mechanically astute, so when they needed to replace their dirt bike tires (at the dealer because they wouldn't get their hands dirty) they would pull the wheels from the bike and, since they couldn't remember where the wheel spacers went, they would put the spacers on the axles and install the axles into the hubs. Now, with their super spiffy high-lifted trucks, they could not reach over the bed sides or even access the back of the bed with the tail gate down without using a ladder, so they threw their wheels onto the floor between the front and rear seats. As they traveled, the wheels would roll across the truck from side to side, causing the exposed axles to deeply scratch and scar the leather upholstery on the front of the rear seat and the backs of the front seats. Yep, tear up the interior of your truck, all for the illusion of being "cool"...
