Tire pressure affects tire ______.

Tire pressure is crucial for both traction and longevity. When tires are properly inflated, they maintain optimal contact with the road, which enhances traction. This is vital for safe braking, cornering, and overall handling of the motorcycle. Proper tire pressure ensures that the tire's surface area is well-distributed on the road, reducing the chances of slippage and improving grip, which is essential for effective maneuvering.

Additionally, maintaining the correct tire pressure impacts the longevity of the tires. Under-inflation can lead to increased wear on the outer edges of the tire, while over-inflation can cause excessive wear in the center. Both conditions can significantly reduce the lifespan of the tires, leading to more frequent replacements and increased costs. Therefore, monitoring tire pressure is essential for both performance and durability, making the option that includes both traction and longevity the most accurate choice.
