Final answer:
Unbalanced tires with low pressure can cause uneven wear, reduced fuel efficiency, and poor handling.
Step-by-step explanation:
Unbalanced tires that also have low pressure can cause problems such as uneven wear, reduced fuel efficiency, and poor handling.
When tires are unbalanced, they can cause the vehicle to vibrate at high speeds, leading to uneven wear on the tires. This can shorten their lifespan and require them to be replaced more frequently.
Additionally, low tire pressure can result in increased rolling resistance, which means the engine has to work harder to move the vehicle. As a result, the car's fuel efficiency is reduced, leading to higher fuel consumption and increased costs.
