Question

1. a tire is being evaluated after a small puncture was found in the sidewall. which of these should be done?

ca. plug the tire.
cb. apply a patch to the inside of the tire.
cc. discard the tire.
cd. install compressed tire sealant through the valve stem.

Explanation:

When a tire has a puncture in the sidewall, it is not safe to repair it. Plugging the tire (Option A) or applying a patch to the inside (Option B) is not a proper fix for a sidewall puncture as the sidewall undergoes significant flexing during normal tire operation, and any repair may not hold up, leading to potential blow - outs. Installing compressed tire sealant through the valve stem (Option D) is mainly for small punctures in the tread area and not effective for sidewall punctures. The safest option is to discard the tire (Option C) as a damaged sidewall compromises the structural integrity of the tire.

Answer:

C. Discard the tire.
