Used tires...

When I was in college I worked for an Auto Parts store, one store I was assigned to put me into the "delivery driver" position. The truck was a real piece of work--once you got past the filth, the shifter was broken off and was replaced by a threaded rod with heater hose over it, the windshield looked like it had been on a golf driving range for a few days, and best of all the tires looked like racing slicks, and there was more. I drove the truck for a few days, notified the manager of the tires and informed him if it rained, I wouldn't be driving his truck. Sure enough it rained 2 days later. The deliveries had to wait until tires were installed that morning. I felt I took a chance on getting fired, but it was a worthy cause in my mind. Had I crashed due to the tires, who knows, maybe I wouldn't need to work anymore?

What's Ma Bell?

Either way, just fishtail a couple of those beasts into some telephone poles, and they'll see how much cheaper new tires are compared to body work.
