The other day my son came home and when he parked the car he heard a tire going down. The next day I took off the tire and while rolling it to the pickup I could hear something inside the tire. The tire was cut and ruined, and while changing the tire we pulled out a yamaha combination #8 and #10 wrench. So if you were riding by my place spying on me, you can stop and get your wrench back!!!! I've seen lots of different stuff in tires, but never a wrench.
