Question

1. a tire cannot be repaired and will need to be replaced if

puncture is outside the middle area of the tire
puncture is larger than ¼ in. or 6mm in diameter
bulge or bubble in the sidewall
all of the above

Explanation:

To determine when a tire must be replaced (not repaired), we analyze each option:

• A puncture outside the middle area (tread's repairable zone) can't be fixed.
• A puncture larger than 1/4 in (6mm) is too big for repair.
• A bulge/bubble in the sidewall means structural damage, requiring replacement.

Since all these situations mandate tire replacement, the correct choice is "All of the above".

Answer:

D. All of the above
