What is the recommended tire pressure for most vehicles?

• 10-15 PSI

• 40-45 PSI

• 20-25 PSI

• It varies depending on the vehicle, but it is typically between 30-35 PSI (pounds per square inch).

Why is it important to maintain proper tire pressure?

• To ensure optimal vehicle performance, improve fuel efficiency, enhance safety, and extend tire lifespan.

• To shorten the lifespan of the tires and reduce safety.

• To decrease fuel efficiency and vehicle performance.

• To increase the risk of accidents and tire blowouts.

How often should you rotate your tires?

• Every 6,000 to 8,000 miles

• Every 10,000 to 12,000 miles.

• Every 15,000 to 18,000 miles.

• Tire rotation reduces the risk of blowouts.

• Tire rotation increases fuel efficiency.

How can you check the tread depth of a tire?

• Look for wear indicators on the tire.

• Use a tread depth gauge or the penny test

• Use a ruler or measuring tape.

• Ask a mechanic to check the tread depth.

What is the minimum legal tread depth for tires in most countries?

• 1.6 millimeters 2/32"

• 2 millimeters 3/32"

• 0.5 millimeters 1/64"

• 3 millimeters 1/4"

What are the signs of worn-out tire tread?

• High tread depth, smooth tread surface, and no visible wear indicators.

• Cracks in the sidewall, excessive vibration, and loss of traction.

• Uneven wear, high tread depth, and excessive noise.

• Uneven wear, low tread depth, visible tread wear indicators, and bald spots.

What are the steps to change a spare tire?

• 1. Locate the spare tire, jack, and lug wrench. 2. Loosen the lug nuts on the flat tire. 3. Use the jack to lift the vehicle off the ground. 4. Remove the lug nuts and the flat tire. 5.
