As the summer season hits its peak, the rising temperatures not only affect us but also have a significant impact on our vehicles, particularly the tires. What should you know about the impact that the heat of the summer months can have on a vehicle?
How do high temperatures impact tires?
Not only is the air temperature higher during summer than it is in the cooler months, but sunny days often mean that the temperature of the pavement is even higher. This means that the tires of every vehicle on the road are in direct contact with this hot surface.
High heat can accelerate tire degradation, increasing the risk of failure. The rubber and other materials used in making tires become more pliable in elevated temperatures. This flexibility means the tire wears down more quickly.
Additionally, hot weather can cause the air inside tires to expand. Tires gain around one pound per square inch of pressure for every 10 degrees the temperature increases. This means that high summer temperatures leading to overinflation. Overinflated tires have less contact with the road, which not only leads to uneven wear but can also make them more susceptible to damage from potholes or debris. Furthermore, the increased internal pressure can lead to a blowout, particularly for worn or damaged tires.
High temperatures are a higher risk for large vehicles.
While the risk of tire failure is a summer challenge for all vehicles on the road, it is particularly dangerous for large vehicles, such as trucks, buses, and trailers. These vehicles carry heavier loads and their tires are under much more stress compared to those on regular vehicles. The heat increases these stresses, potentially leading to catastrophic tire failures.
For large vehicles, tire blowouts can be particularly dangerous, not only for the driver but also for all road users. A blowout in a large vehicle can result in loss of control, leading to severe accidents. The higher temperatures can increase the rate at which the tire rubber degrades and can amplify the effects of underinflation or overinflation.
It is important for drivers to understand the way that high temperatures can impact the tires of their own vehicle and for the vehicles they share the road with. Being aware of these risks can help you properly maintain your own vehicle manage the risk of a car accident when you go driving on a summer day.
