Can a Car Run Continuously on the Highway in Hot Weather?

[DiJayce]

Generally, in the high-temperature conditions of summer, it is best not to drive on the highway for more than 3 hours. This is because when driving during the daytime in summer, the ambient temperature often exceeds 35°C, and the ground temperature can be as high as 60°C or more. The heat radiating from the ground affects the engine's cooling system, creating a wave of heat that continuously surrounds the engine. Therefore, it is recommended not to drive continuously for more than 3 hours. Below are the impacts of driving on the highway in hot weather: When the temperature is above 30°C, the air pressure inside the tires can increase by 10% to 12%, making the tires prone to bulging. If the tires already have scratches, the likelihood of a blowout significantly increases. In summer, the road surface temperature can reach 60~70°C, and if the tire pressure is too high, even minor weaknesses in the tires can easily lead to a blowout.
