6. Procedures/Methods-

A. Introduction-


1.Hand out "how to change a flat tire" power point.
2.Watch DVD on "how to change a flat tire".
3.Discuss safety while changing a tire.
4. Explain the purpose of the class by showing how to change a tire safely.
5.Reading through each objective and check for understanding of them.


1.A person would choose to change their tire when it is flat, low on air, or has blown up/ separated while driving.
2.The main key to this task is for students to realize that changing tires also can be very deadly.


B. Development-

1.Students realize that tire is flat and they need to change it. "If on the road and the tire goes flat pull over to the side of the road away from traffic, avoiding being hit by other motorest". Illustrate a safe place to change the tire so that the location is flat and as far off the road as possible,vehicle is in a parked gear and the emergency flashing lights are on. If there is a heavy rock nearby to place it blocking the opposite side of the tire.
2.Take the owners manual and show students how to utilize the index to find section on changing tires to determine where to place the jack.
Demonstrate the purpose of and the specific workings of the jack that is in the vehicle.
Retrieve the jack, lug wrench, and spare tire out of the truck or designated area.
3.Take the jack and according to the vehicle manufacturing design place the jack in the proper lifting position.
4.Once jack is under vehicle use the lug wrench to loosen the lugs holding the wheel on that you would like to change. Using the tire iron demonstrate how to loosen the lug nuts...not remove but loosen.
5.Lugs are now loose jack up the care until the desired tire is off the ground using your jack you implaced.
6.With the lug wrench take off all lug nuts on the tire and remove the desired tire off the vehicle and setting it to the side.
7.Then grab the spare tire and place it in the same spot that the other tire was and fastening it down with the lug nuts and lug wrench.
8.Then lower the jack to were the vehicle is putting enough pressure on the tire you just changed so that it will not move while you use your lug wrench to tighten the lugs using leverage.
9.Once lugs are tightened then lower the vehicle all the way down to where you are able to retrieve the jack from out under the vehicle
10.Then gather up your jack, lug wrench and bad tire and place them back into their designated areas.
11.You may now return to your car and drive away after you have walked around your car to make sure you didn't leave anything behind.

Technique Breakdown

1.Put the car in park on level ground and apply the parking brake. Place manual transmission cars in gear. Make sure you have pulled off the road. Turn the engine off and turn on the hazard lights. You may want to open the hood to indicate to other drivers that you are stopped for repairs.

2.Place a wheel chock or a large rock behind (if facing uphill) or in front (if facing downhill) the diagonally opposing wheel to prevent the car from rolling. Do this even on a slight incline. Get out the spare, a lug nut wrench (tire iron) and the car jack.

3.Remove the hubcap, if necessary.

4.Loosen the lug nuts, which hold the wheel in place, before jacking up the car: Place one end of the lug nut wrench over a lug nut. Use a hollow pipe (about 2 feet in length) for leverage by slipping it over the end of the lug nut wrench. Turn the wrench counterclockwise to loosen the lug nut. Loosen the lug nuts in a star pattern, first loosen one a few turns, then loosen the one opposite. Work across the tire until all the lug nuts are loose and unscrewed slightly.

5.Carefully jack up the car. Check your owner's manual for the correct and safe place to put the jack. Jack the car up a little higher than is necessary to remove the old tire so there is room to put the new, full tire on.

6.Remove the lug nuts all the way and set them aside in a place where you won't lose them and they won't roll away. The flat tire should be hanging from the threaded studs now.

7.Remove the flat tire and set it aside.

8.Lift the new tire onto the wheel studs. If you're confused about which is the right way to put the new tire on, check for the valve where you add air, it always faces out.

9.Replace the lug nuts. Tighten them the same way you loosened them: Give each nut a few turns, first one, then the one opposite, working around the wheel in a star pattern. Try not to tighten adjacent nuts consecutively.

10.Slowly lower the jack and remove it.

11.Tighten the lug nuts again as much as you can.

12.Put the hubcap back on.


C. Practice-

1.In groups of five us the six vehicles outside and in the bay for your in class practice
2.Each person in the group will assist one person in demonstrating the task.
3.Students may assist the by telling the demonstrator which step to do but they my not physically assist.


1.Have students familiarize with the tools needed.
2.Explain to class how to change a tire.
3.Depending on how many students are in class, have them form groups to change an actual tire.
4 Have 3 vehicles available for the students to actually change a tire an be sure that all the tools they need will be available.
5.Have each student go through the process of changing a tire while being monitored by the instructor or assistants.
6.Give feedback to the individual student on their progress as they go.


D. Independent Practice-

1.For homework the students will go home and ask their parents to watch them change the tire out on the family car and then in reverse take the spare of and put the original back on.
2.Students will have their parents follow the guided set instructions and sign at the bottom indicating that they view their children doing the homework exercise.


1.Have students read an article silently on "What safety measures to take when changing a flat tire".
2.Have students break into group discussion.
Asynchronous simulations of specific scenarios on the web looking for the student to judge: location where a tire is to be changed; proper procedures, using the correct tools.
3.Answer questions or concerns relating to changing a flat tire. Checking for understanding questions in the web based simulations that match answers with concepts or answers with tools.


E. Accommodations (Differentiated Instruction)-

1.For student that can not perform this task there will be a allotted time at the end of the day on Thursday. Students well be able to use my truck for the assignment and will be able to catch the activities bus home.
2.Students my also come auto shop on their lunch break and due their assignment.

3.If there are women who do not feel comfortable with the lesson in the class have them watch a video on "how to change a tire".
4.When would someone call for help when they have a flat tire due to safety reasons.
5.Does not have the proper tools, where to purchase them.

1.If the student is physically handicapped the best recommendation would be for them to call a service vehicle for assistance.
2.If the student is small in build and stature, the instructor can suggest that two people change the tire and if a 2nd person is not available to call a service vehicle to avoid injury.


F. Checking for understanding-

1.Students will be judged by a test of the knowledge.
2.Students will be called on to answer which step is next during the in class practice
3. Before student changes tire, make sure they understand all of the steps.
4.Demonstrate how to change a flat tire.
5. Ask students if they have any questions during the demonstration.

G. Closure-

1.Expressing why its important have the knowledge of how to change a tire.

2.Hand out an evaluation to students to put down recommendations for the next class.
3.All students as a class will have to walk somebody through changing a tire by using a talk through method of instructing. The Demonstrator will not do anything that was not directed.

Advanced Advice:

1.Student feedback...what they would like to see or not see changed if done again.
2.In the student enactment of changing a tire seeing a flow from one step and process to another.

8. Teacher Reflection-

The teacher feeling good that each student has the ability to change their own tire if the situation calls for it.

1. Evaluate student feedback...how can the course be improved?
2. Celebrate it's successes!
