During a pre-trip inspection, it is essential to check both the tire pressure and tread depth. Proper tire pressure is crucial for safe driving, as underinflated or overinflated tires can lead to handling issues, increased wear, and even blowouts. Maintaining the correct tire pressure helps ensure optimal fuel efficiency and braking performance.

Tread depth is equally important because it affects traction on the road. Insufficient tread depth can lead to poor grip, especially in wet conditions, increasing the risk of hydroplaning and loss of control. Most states have guidelines for minimum tread depth, and it's vital for drivers to be aware of and adhere to these standards to enhance safety.

Other options focus on different aspects of tire maintenance. Checking the color of the tire tread is not a reliable indicator of tire health or performance. While knowing the age of the tires can provide insight into their potential degradation, it does not directly impact immediate safety measures like pressure and tread depth. Lastly, ensuring that tires match in size and brand is part of a comprehensive tire management strategy, but it is not as critical as monitoring pressure and tread depth for safe operation on the road.
