If you’re like most drivers, you probably have a few flat tires lying around your garage. But before you go out and buy a new set of tires, there are a few things you can do to try and fix them yourself. The first thing you need is some tire iron or a similar tool. You can use this to puncture the tire’s inner tube and cause it to deflate. Once the tire is deflated, use the tool to flatten it out. This will help it hold air and last longer. If that doesn’t work, you can try using a plunger or bucket to push the air out of the tire. Be careful not to overdo it, though – if the pressure is too high, the tire could burst. ..
