In tire inspection, what two tasks should be performed?

• A. Measuring tread depth and verifying tire matching
• B. Checking sidewall color
• C. Replacing tires every 6 months
• D. Balancing tires without measuring tread

Answer: (A)

Two main tasks in tire inspection are measuring tread depth and verifying that the tires are matched. Measuring tread depth checks how much rubber remains and whether there’s enough grip for safe braking in various conditions; wearing tread too low reduces traction and lengthens stopping distances. Verifying tire matching means making sure the tires are the same size, construction, and have compatible tread patterns so they wear evenly and the vehicle handles predictably; mismatched tires can cause unstable handling and uneven wear. The other options don’t fit standard inspection practice: sidewall color isn’t a reliable indicator of tire health, tires don’t have to be replaced on a fixed schedule like every six months, and balancing alone doesn’t address tread wear or tire compatibility.
