1. Increased Tire Pressure
Hot weather causes air to expand. As temperatures rise, so does the pressure inside your tires. For every 10°F (about 5.5°C) increase in temperature, tire pressure can rise by about 1–2 PSI (pounds per square inch). While that might not seem like much, overinflated tires can lead to:
Always check your tire pressure regularly, especially in summer, and adjust it to the manufacturer’s recommended level — usually found on a sticker inside the driver’s door or in the owner’s manual.
2. Rubber Degradation
UV rays from the sun can cause the rubber compounds in your tires to break down over time. Prolonged exposure can lead to:
To minimize sun damage, park in the shade or use a car cover when possible. Regular tire inspections can also help you spot signs of UV damage early.
3. Increased Risk of Blowouts
Hot pavement combined with increased internal pressure and older tires is a dangerous mix. The higher the temperature, the more stress is placed on the tire structure. Worn-out or under-maintained tires are especially prone to failure in such conditions.
Blowouts at high speeds are not only inconvenient — they can be deadly. To prevent this, ensure your tires are in good condition, not overly worn, and properly inflated.
4. Faster Tread Wear
High temperatures can soften the rubber, which leads to faster tread wear — especially if you're driving on hot asphalt. This is particularly true for aggressive driving styles, such as sudden stops or fast cornering, which generate additional friction and heat.
Rotate your tires regularly, maintain proper alignment, and drive smoothly to extend their lifespan during summer months.
5. Uneven Tire Aging
If one side of your vehicle is exposed to the sun more often (for example, parking the same way every day), the tires on that side may age faster. This can result in uneven wear, reduced performance, and potentially dangerous handling issues.
Consider rotating parking spots or switching the direction you park to allow for more even exposure and aging.
The sun and high temperatures can have a significant impact on the safety, performance, and longevity of your car tires. A few simple precautions — like checking tire pressure, avoiding direct sun exposure, and keeping up with maintenance — can go a long way in protecting your vehicle and everyone inside it.
Stay safe this summer — keep your tires cool, inflated, and in good shape!
