The option that is not an effect of low tire pressure would be B. increased risk of blowout.
What happens as a result of low tire pressure ?
Low tire pressure can cause the tires to deform, which increases rolling resistance and reduces fuel efficiency. Low tire pressure can prematurely wear out the tread of the tire, which can lead to uneven wear and premature tire failure.
The increased risk of blowout is not the result of low tire pressure. In fact, low tire pressure can reduce the risk of a blowout by ensuring that the tire is properly inflated and that the tread is in good condition.
Options for this question are:
Increased fuel consumption
increased risk of blowout
Reduced tire life
Reduced handling
