How To Change A Tire

If you’re a new car owner and you’ve never had to change your own tire before, it’s an invaluable skill that will save you a lot of hassle in the future. You don’t have to wait for roadside assistance or for a friend to come pick you up so long as you know how to handle a tire iron and a jack. Here’s what you need to know about swapping out a blown tire for a new one:

Make Sure You’re on Solid Ground

The process can be dangerous on loose gravel or sand or grass, so make sure that you’re on the concrete or tarmac before you start changing your tire. You can drive or push your car safely a little ways before you do any real damage, but at this point it’s still important not to put too much stress on the wheel itself without a good tire on it, so be quick so that you don’t do any real damage to the axle and wheel.

Put on the E-Brake

This will keep your car from slipping and sliding while you go to work on it.

Find the Divot

There will be a small divot, about the size of a small fist on the body of the car somewhere around the tire. That’s where you place the jack. Anywhere else and you’ll either damage the car or you’ll wind up with a loose grip between the jack and the car.

Lift the Car

When lifting with the jack, it’s important to stay a safe distance. Don’t have your foot right in the way of the car if it slips. You never know what can happen when your car is supported on a jack.

Remove the Hubcap and the Lugnuts

Take the tire iron and remove the lugnuts in a counterclockwise motion. Use a little WD40 if they get stuck.

Replace

Take the busted tire off the wheel, put the new one on, tighten the lugnuts, put the cap back on and lower your car down.Now, you can’t just toss that tire in the trash, you’ll need to have it repaired or properly disposed of. And now, you should be prepared in case you get a busted tire out on the road.

Keep Your Eye On The PSI To Save You Gas

Can buying the right tires save you in extra fuel costs? Can keeping your eye on the PSI (pounds per square inch) save you gas? The simple answer is, “Yes”. Rolling resistance and friction play a huge part in the amount of fuel you save. Simply speaking, the more rolling resistance and friction, the less miles per gallon you are going to get out of your car. If your tires are inflated to the right pressure, then a tire with low rolling resistance can give you as much as an additional 3 miles per gallon in extreme cases.

Under the weight of your car the tire is distorted with every turn of the wheel. Now, when your tires are under-inflated, the rubber distorts under the heavy weight of the car and bells out and more surface area of the tire touches the road. It stands to reason that your car will have to generate more energy to create continuous forward movement. The more rubber on the road, the more fuel your engine needs to move the car and the less you save in gas.

This video explains further the physics behind rolling resistance and how it affects your gas mileage.

Even being under inflated by a few pounds, your tires are not going to perform the way they should. If you don’t think that the inflation of your tires plays such a definitive role in keeping money in your pocket, think again.
