During a pre-trip inspection, what is important to note about tires?

During a pre-trip inspection, it is crucial to check for the correct pressure and tread depth of the tires because both of these factors directly impact safety and vehicle performance. Proper tire pressure ensures that the tires can handle the weight of the vehicle and provide adequate traction. Over-inflated or under-inflated tires can lead to poor handling, increased tire wear, and even tire blowouts.

Tread depth is equally important as it affects the vehicle's grip on the road, especially under wet or slippery conditions. Insufficient tread depth can lead to decreased traction and longer stopping distances, which can compromise safety. Therefore, ensuring that both tire pressure and tread depth are within the recommended specifications is vital for safe operation.

The other options, while they could relate to tire condition, do not address the key safety factors required for a pre-trip inspection as effectively as checking for pressure and tread depth.
