Talk about an important basic skill to have and you’re talking about knowing how to change a flat tire. Although we could always wait for our man to show up and change it for us, there are times when we either don’t have a man around, or he’s off on a trip somewhere and we’re well and truly stuck.
If that’s the case, don’t depend on the kindness of strangers. Knowing how to change your own flat tire is key to your safety and security on the road.
Park the car on firm and level ground, as far off the road as you can get it safely, and get to work quickly. You don’t want to be there any longer than you have to, especially if it’s a busy highway.
First, set the parking brake. If you have an automatic transmission, make sure you put it in park, and if you have a manual, put it in reverse. Chock the tire that’s on the opposite side and opposite end of the car from the one you’re changing (that’s the one diagonally across from the flat tire).
What’s “chock the tire” mean? It means to put a block, rock, piece of lumber, or something to keep the car from rolling. Specifically, to keep it from rolling off the jack when you get the car up there.
Next, take the jack and spare time from the trunk and any other tools included in the spare tire area. You might need a special tool to remove the hubcap, but if there’s nothing included, just pry it off with the tapered end of the jack handle or a big screwdriver. You do have one of those in your trunk, right?
Use the lug wrench (the l-shaped tool that has what looks like a socket head on one end and a pry bar on the other) and loosen the lug nuts before you raise the car. It’s much easier and safer to do it now and not after you get the car on the jack. To loosen them, you should turn them counterclockwise. If you have a weird car that has lugs that loosen by turning clockwise, they should be marked. You just don’t want to end up trying to tighten them when you’re working so hard to get them off. Don’t be afraid to put some muscle behind the lug wrench. It’s seriously unlikely that you’re going to be able to loosen the lugs without some real effort.
Next, you’ll need to assemble the jack. Hopefully, your jack will have instructions in the owner’s manual or on labels affixed to the jack itself. You might even find them under the trunk lid, but don’t count on it.
Now you’re ready to position the jack. Make sure you put it in the proper place. The instructions for jack placement should be with the instructions for putting the jack together. The thing is, you don’t want to put a jack that’s meant to go under the axle under the bumper and vice-versa. Safety is important and placing a jack in the wrong place is a disaster waiting to happen.
When the jack is in position, insert the handle, crank it clockwise (or up and down, or whatever the instructions say), and slowly raise the car until the flat tire is about 3 or 4 inches off the ground.
Make sure the car is steady. If it’s not, you need to lower it and start over, because you don’t want the care to end up falling off the jack while you’re changing out the tire.
When the car is steady, take off the lug nuts and put them in a secure location. If you lose one, you’ll be in big trouble! Next, take off the wheel and replace it with the spare. Line up the wheel studs with the mounting holes, and make sure the right side of the wheel is facing outward. This can be difficult because tires and wheels are heavy, but this is not the time to worry about getting your shirt and trousers, or skirt, dirty. It’s going to happen, so you might as well get on with it.
Push the spare wheel flat against the mounting surface, and starting with the bottom wheel stud, screw on the lug nuts by hand. Make sure the tapered side faces the wheel so they’ll lock in place. Once you’ve done them all, tighten the lugs with the lug wrench, gently, because you don’t want to knock the car off the jack.
Finally, lower the car to the ground, turn the crank on the jack counterclockwise to release it, and then get the jack out of the way. Now’s the time to use the wrench to tighten the lugs as tight as you can get them. Don’t just go around the wheel in a circle tightening them. Crisscross the wheel, tightening the lugs that are diagonally across from each other until you’ve got them all as tight as possible.
Pack away your flat tire, tools, and materials and be sure not to leave anything behind. And get that tire fixed and replaced as soon as you can.
