Let's go through each question on the worksheet
"How to change a tire" and provide the correct answers with explanations.
---
1. What is the first step in changing a tire?
✔ Loosen the lug nuts
Explanation:
Before jacking up the car, you should
loosen the lug nuts slightly (but not remove them) while the car is still on the ground. This is important because once the car is lifted, the wheel can spin freely, making it harder to loosen the nuts. Use a wrench or tire iron to turn the lug nuts counterclockwise.
---
2. What should you use to loosen the lug nuts?
✔ A wrench
Explanation:
The correct tool to loosen lug nuts is a
wrench, typically a lug wrench that comes with the vehicle. A hammer, screwdriver, or pliers are not appropriate for this task.
---
3. How many lug nuts are typically on a tire?
✔ 5
Explanation:
Most vehicles have
5 lug nuts per wheel. However, some cars may have 4 or 6. But
5 is the most common number across standard passenger vehicles.
---
4. What should you do before jacking up the car?
✔ Loosen the lug nuts
Explanation:
As mentioned earlier,
loosen the lug nuts while the car is still on the ground. This prevents the wheel from spinning when you try to remove it later.
---
5. Where should you place the jack when jacking up the car?
✔ On the frame
Explanation:
Always place the jack on the
vehicle’s frame or designated jacking points. Never use the bumper, axle, or steering wheel — these are not designed to support the car’s weight and could cause damage or collapse.
---
6. What should you do before removing the flat tire?
✔ Loosen the lug nuts
Explanation:
You must
loosen the lug nuts before removing the tire. They are usually tightened very securely, so they need to be loosened before the car is jacked up and the wheel removed.
> Note: The other options like "Put on the spare tire" or "Check the tire pressure" happen after the flat tire is removed.
---
7. What should you do after putting on the spare tire?
✔ Lower the car
Explanation:
After placing the spare tire on the hub and tightening the lug nuts by hand,
lower the car using the jack. Then, fully tighten the lug nuts with a wrench in a star pattern.
> Other steps:
> -
Remove the hubcap – done *before* removing the flat tire.
> -
Drive to a mechanic – only if the spare is temporary.
> -
Check the tire pressure – good practice, but not the immediate next step.
---
8. What is the recommended tire pressure for most cars?
✔ 35-40 PSI
Explanation:
Most passenger vehicles recommend
35–40 PSI for proper tire inflation. This range ensures optimal performance, safety, and fuel efficiency. Always check the manufacturer’s recommendation (usually found on the driver’s side door jamb or in the owner’s manual).
> Note: 25–30 PSI is too low; 45–60 PSI is too high for most cars.
