A few years ago a tire on a boat trailer blew out during a long trip. It turned out that my boat trailer had nuts of a different size than my truck and I was stuck for a couple of hours. I bought this kit and packed an impact wrench for my trip this summer. Of course, the tire failed again on the track. With a set of wheel nuts and an impact wrench, I was back on the road in 20 minutes. It was much faster and safer than doing it by hand and saved me and my family from a dangerous situation. The purchase was worth it for the quiet alone. I also intend to use this to make removing the lawnmower blade easier.
