Introduction
Sooner or later, everyone gets a flat tire. And chances are it won’t happen a good
time.
I can hear some of you saying “Why should I learn to change my tire? I have road
side assistance.”
Roadside assistance isn’t always reliable, especially during the holidays or in
remote areas.
Consider the average response time for roadside assistance is thirty to forty
minutes. In most cases, you can change your tire in less than ten!
The best time to learn to change your tire is before you get a flat tire. That’s what
this course is all about.
We have a lot to cover, so let’s get started!
Slide-2
Safety First!
If your tire goes flat while you’re driving, pull over to a dry, level place as far from
the road as possible.
It’s better to drive a short distance on a flat tire than risk your life changing the
tire in an unsafe area.
Once you’re safely parked: turn off the car, apply the parking brake, turn on the
emergency lights and open the car hood.
NOTE: Opening the car hood signals other drivers you’re stopped for repairs.

Step 1: Gather Your Tools
Get started by taking the necessary tools from your trunk. Roadside kits vary, but
you need four items to successfully change your tire.
Those items are:
1.
2.
3.
4.
a spare tire
car jack
tire iron and,
wheel chocks.
Roadside kits can include additional accessories such as: road flares, gloves,
flashlights and jumper cables.
NOTE: Some wheels have a locking wheel bolt which requires a special key to
remove the wheel. If you have trouble removing a lug nut, check the glove box
for the key.
Slide-4
Step 2: Chock the Wheels
“What are chocks”
Wheel chocks are wedges of sturdy material placed behind the wheels to prevent
accidental movement. If you don’t have chocks you can use bricks or wood blocks
as long as they’re heavy enough to prevent the car from moving.
“How do I chock the wheels?”
To chock the wheels, place the chocks on the wheel diagonally opposite of the
wheel you’re replacing.
For example, if you’re replacing the right rear wheel, you’d chock the front left
wheel.

Wheel Chocks
Wheel chocks (or chocks) are wedges of sturdy material placed behind
a vehicle's wheels to prevent accidental movement.
Chocks are placed for safety in addition to setting the brakes.

A mechanical jack is a device which lifts heavy equipment. The most
common form is a car jack, floor jack or garage jack which lifts vehicles
so that maintenance can be performed.

Tire Iron
A tire iron is a specialized metal tool used in working with tires that
have inner tubes. It is often incorporated with a lug wrench on one
end.

Spare tire
A spare tire is an additional tire carried in a motor vehicle as a
replacement for one that goes flat, a blowout, or other emergency.
Spare tire is generally a misnomer, as almost all vehicles actually carry
an entire wheel as a spare, as fitting a tire to a wheel is very difficult
without specialized equipment, and is not practical in an emergency.
However, some spare tires are not meant to be driven long distances
and most of them have maximum speed of around 50 mph.
Slide-6
Step 3: Loosen the Wheel Nuts
To loosen the wheel nuts:
1. Position the tire iron so the handle rests at three o’clock.
2. Grasp the wrench near the end and push down in a counter clockwise
direction. Remember: Righty tighty , lefty loosey
3. Loosen the wheel nuts about a half turn of the wrench. They’re loose
enough when you can turn them with your hands.
Did you know? Loosening the wheel nuts before raising the car prevents
unnecessary strain on the emergency brake. The weight of the car helps hold the
wheel in place so your tire iron turns the wheel nuts rather than the wheel.
Slide-7
Step 4: Raise the Car
To raise the car:
1. Position the jack’s base on a solid, level surface near the tire you’re
changing. Most cars will have a small notch where the jack fits under the
car frame. This area has been specifically reinforced to accommodate the
jack.
2. Insert the handle into the jack and slowly crank clockwise until the wheel

is high enough off the ground to remove the tire. Two to three inches
should be enough.
Caution: Never get under a vehicle when the vehicle is on the jack.

Couple things to notice here. First, he’s wearing gloves. Tire changing is messy
and thin garden gloves can make a big difference.

Also, notice the car is only raised about two inches from the ground. You only
need enough clearance to remove the tire. Raising the car too high is dangerous
and increases risk for injury.

Step 5: Remove the Wheel Nuts
To remove the wheel nuts, use your hands to:
1. Unscrew and remove the wheel nuts.
2. Place them in a safe spot such as your pockets or in the hubcap.
Caution: If you’ve been driving, be careful handling the wheel nuts – they could
be hot!
Slide-12
Step 6: Replace the Tire
To replace the tire:
1. Grab the tire with both hands and slide it off the lug bolts.
2. Lay the tire on its side to prevent any chance of rolling away.
3. Place the spare tire onto the car by aligning the wheel holes with the lug
bolts.
Note: Make sure the air valve is facing out and away from the car. If it’s facing
inward, the tire is facing the wrong way!
Slide-13
Step 7: Return the Wheel Nuts
Double-check the wheel to ensure it’s all the way back on the hub.
Reinstall the wheel nuts and tighten them using only your hands.

Step 8: Lower the Car
Lower the car by slowly turn the jack handle counter-clockwise to lower the car.
You’ll know the car is all the way down when the jack comes loose.
You can now remove the jack from under the car.
Slide-15
Step 9: Tighten the Wheel Nuts
Select a wheel nut – it doesn’t matter which one.
Using the tire iron, tighten the wheel nut as tight as you can.
Next, tighten the wheel nut diagonally oppose the wheel nut you just tightened.
If you tire has an odd number of wheel nuts, just select the nut almost diagonally
opposite.
Continue this pattern for the remaining wheel nuts.
Note: The crisscross pattern helps ensure the wheel is correctly on the hub.

Step 10: Clean Up
That’s it. Check your time. How’d you do?
Return the chocks, tire jack, tire iron and flat tire to their proper storage place in
the trunk.
