The correct answer about driving in hot weather is that it's important to check tire mounting and pressure before driving. In high temperatures, tire pressure can increase significantly due to the heat generated from both the environment and the friction from the road. Under-inflated tires can cause overheating and lead to tire blowouts, which pose a major safety risk. Therefore, ensuring that tires are properly mounted and at the correct pressure is crucial for safe driving in hot weather.

Considering the other options, focusing solely on the air conditioning system does not address the broader safety concerns related to driving. Driving faster to increase airflow is counterproductive and can create additional risks, including reduced control and increased stopping distances. Additionally, neglecting to check tire conditions can lead to dangerous situations, as it can overlook critical issues that may arise due to severe heat. Prioritizing tire checks is essential for safe travel during warmer months.
