What does it mean if a tire is "under-inflated"?

Answer: B — It has less air pressure than specified by the manufacturer

When a tire is described as "under-inflated," it means that the air pressure within the tire is lower than the recommended level specified by the manufacturer. Proper tire pressure is crucial for several reasons: it ensures optimal contact with the road, enhances handling and stability, improves fuel efficiency, and reduces the risk of tire blowouts. Under-inflated tires can lead to several issues, including increased tire wear, decreased traction, and compromised safety. This condition can also affect the vehicle's braking distance and overall performance, making it vital to regularly check and maintain tire pressure to stay within the manufacturer’s guidelines for safe operation. It’s an important aspect of motorcycle safety and maintenance that every rider should prioritize.
