What must be checked regarding the tires during a safety inspection?

Tire tread depth and pressure are crucial components that must be checked during a safety inspection. Tread depth is vital because it affects the vehicle's ability to grip the road, especially in wet or slippery conditions. Insufficient tread can lead to hydroplaning or reduced traction, increasing the risk of accidents.

Additionally, proper tire pressure is essential for safe vehicle operation. Under-inflated tires can cause poor handling, increased tire wear, and a greater likelihood of tire blowouts. Conversely, over-inflated tires can also lead to handling issues and uneven tire wear. Thus, ensuring that tires are at the correct pressure and have adequate tread depth directly contributes to the overall safety of the vehicle.

Checking for tire color and design, brand and model, or alignment doesn't directly relate to the safety concerns that tread depth and pressure address, making them less relevant in a safety inspection context.
