What is a common consequence of not checking tire pressure regularly?

Increased fuel efficiency Improved vehicle handling Increased tire wear and potential blowouts Better traction on the road

Correct Answer:

Increased tire wear and potential blowouts

Explanation:

Not checking tire pressure regularly can lead to increased tire wear and a higher risk of blowouts. When tire pressure is too low, it causes the tires to flex more than they should, generating excessive heat and leading to faster wear of the tire tread. Under-inflated tires create additional rolling resistance, which can also break down the tires' structural integrity over time. This not only shortens the lifespan of the tires but also increases the likelihood of a blowout, which can pose significant safety hazards while driving. Maintaining proper tire pressure helps ensure optimal contact with the road, extends tire life, and enhances overall vehicle safety.
