Nobody likes to get a flat tire, but the reality is that flats happen. When you do, there's no need to panic, though, because you have several options for fixing most flat tires. Of course, if there's an underlying problem with the rims or suspension you may want to take your car to a mechanic - but before you do, I suggest you check outA Mechanic Comes Clean - this book has lots of tips that will keep you from getting scammed at the car repair shop.
Here's how to change a flat tire:
- What not to fix: Sometimes, such as when you have a blowout, the tire will go flat and it cannot be repaired. If the tire explodes, is lacerated, or has significant damage, no attempt should be made to repair the tire. It must be properly disposed of so that it can be recycled. Also, if the sidewall of the tire is damaged or cracked, don't bother trying to repair it. Get that tire replaced and have the tire company dispose of the old tire. Finally, tires with less than 1/16th inch of tread should be replaced rather than repaired. (You can measure your tread depth with a tread depth gauge.)If the tire deflated because something like a nail punctured through the tread (the part of the tire that contacts the pavement), then you have a couple of options for fixing the flat tire. It is difficult to assess the damage to your tire when it's still mounted on the car so you'll need to remove the tire before you can begin any automotive repair steps. Place a block or wedge under the tires to keep them from moving, set the emergency brake, and remove the tire from the vehicle. Be sure to loosen the lug nuts with a lug wrench before lifting the car with a jack. After the tire is off the ground, remove the lug nuts by hand, and pull the wheel and tire away from the car. If you have a decent spare, consider putting it on and moving the car to a safe location.
- Find the culprit: Sometimes it's very obvious why the tire deflated. You may see the head of a nail, screw, or some other metal object lodged in the tire tread. If so, circle it with anything that will mark the tire so that you can easily spot its location later. Don't remove the object until you're prepared to fix the hole.Note: If you've picked up a nail or screw in the tire, it's possible that you've picked up more than one object. Even after you've found one, it's still a good idea to check the rest of the tire for leaks or embedded objects.How To Repair Flat Tires: Car Repair
