I think this is a must have if you want to change tires yourself. This company knows about tires; The length, the shape, the perfectly positioned lugs are all designed for easy tire-on-rim removal and replacement. I've used it on pickup tires, car tires, trailer tires, and 4 wheel tires. Also suitable for truck and tractor tires. It would not be without. Forget screwdrivers and buy this tool; you will not regret it. Highly recommended!
