Answer :
Final answer:
Tires are considered a safety hazard when underinflated by more than 5 psi because they may compromise vehicle handling, increase blowout risk, and affect fuel efficiency.
Explanation:
Tires can become a serious safety hazard if they are underinflated by a certain amount. While each vehicle may have specific tolerances for tire pressure variance, a common standard for when a tire is considered significantly underinflated and potentially hazardous is 5 psi below the recommended level. This underinflation can impact vehicle handling, increase the risk of a blowout, and affect fuel efficiency. Moreover, proper inflation ensures optimal tire lifespan and safety on the road. Therefore, tire safety becomes compromised if they are underinflated by more than 5 psi, which would be option A.
