Do Tires Need Watering for Long-Distance Driving?
2 Answers
No. Many people have a misconception that when a vehicle drives long distances, the wheels will generate high temperatures that affect braking and wheel lifespan. This is an incorrect understanding. Wheel Cooling: Long-distance trucks are equipped with water sprinklers to cool the wheels. This relates to the structure of the braking system. Large vehicles use drum brakes, which have poor heat dissipation. High temperatures can reduce braking efficiency. Heavy trucks driving overloaded for long periods or continuously braking on downhill mountain roads may experience dangerous situations due to reduced braking performance. Front and Rear Disc Brakes: Modern cars use front and rear disc brakes, which have excellent heat dissipation and high braking efficiency. They are widely used in modern vehicles.
I find this question quite interesting because many novice drivers have this misconception. Pouring water on tires is absolutely not okay, and the reason is simple: water can instantly make the tire surface slippery, which may cause skidding or loss of control at high speeds—extremely dangerous. I’ve seen someone try this before, and the car ended up fishtailing during a turn, nearly hitting the guardrail. It’s normal for tires to heat up during long-distance driving due to friction-generated heat, but they can withstand certain temperatures. Pouring water to cool them down can actually harden or crack the rubber surface, reducing grip. The right approach is to ensure proper tire pressure—check it before departure to avoid underinflation; avoid overloading; maintain a steady speed while driving without sudden acceleration; and take breaks every two to three hours for about ten minutes to let the tires cool naturally. Extra caution is needed in hot summer weather—park in the shade to rest. Remember, safety comes first—tire issues are no small matter. Regular maintenance and inspections can prevent major problems.
