Tiretool_v2

Hello there, Here is another entry. The principle is simple and the basics are the same like in my other entry (Tiretool_v1). The difference is that this model does not require a central axis, it has a supporting leg with a rubber head. The procedure is like this: 1. You swing the 2 arms (the extracting one and the mounting one) to a 180 degrees angle so you get a big lever to separate the tire from the wheel. 2. You fix the supporting leg on the wheel (rim). 3. You swing the arms (the extracting one and the mounting one) until they get fixed on the supporting elbow. 4. You start pressing on the arm, and step by step move the supporting arm until you get the whole tire off (see pictures for a better idea). Advantages (from my other entry) : it is easier to mount and it is more portable. Disadvantages : more force required (Solution : should have some bearings on the central axis but this would imply a higher cost) . Hope you like it! Best regards!
