Goodyear Blue Streak…Mud and Sand Here is the finished tire. We are betting these tires were used and had seen their day on the drag strip based on the cords showing on some of the cut areas. Observant Jeepers will also notice that the wheel has been widened and has self-tapping screws going into the bead of the tire. The sidewall screws were a cheap alternative to a beadlock wheel and kept the tire from spinning on the wheel during drag racing, but may also help with aired-down Jeep tires. Also, in the rear of this photo by Eric Rickman on the ground and mounted to a CJ, you can see another early off-road tire option in the form of 11.00x15 Armstrongs. Intended for tractors, the Armstrong farm implement tires were pretty large in diameter and width and could be grooved for extra traction off-road.
