Why Tire Blowouts Spike in Summer and How to Prevent Them

If you've ever experienced a tire blowout while hauling a heavy or oversized load, you know it’s more than just an inconvenience—it can be dangerous and costly. 

Summer is peak season for tire failures, especially in the heavy haul industry, where load stress is already at a maximum. But why exactly do blowouts spike in the summer months, and more importantly, how can you prevent them? We dive deeper to keep you safe and prepared on the road as things heat up!

The Science Behind Summer Blowouts

Tire blowouts are often caused by a combination of heat, friction, and pressure. During summer, pavement temperatures can reach 140°F or more. 

As the road heats up, so do your tires—especially under the weight of a heavy haul. Hot air expands, which means tire pressure can quickly rise beyond safe limits. Combine that with worn tread, underinflation, or overloaded axles, and you have the perfect storm for a blowout.

Underinflation: The Hidden Risk

One of the most common causes of summer tire blowouts is underinflation. While it may seem like an overinflated tire would be the issue, underinflated tires generate more heat due to increased surface contact with the road. 

That excess friction builds up heat and weakens the tire’s internal structure. Make it a habit to check tire pressure daily, and always when the tires are cold—not after a long haul in the heat.

Monitor Load Distribution

Even with proper tire maintenance, poor load distribution can put excessive stress on individual tires. Uneven weight on axles or improperly secured freight increases the likelihood of tire failure. 

Always double-check your load balance before hitting the road, especially for oversized or irregular shipments.

Inspect Tread and Sidewalls Regularly

Worn or damaged treads are more susceptible to heat-related failures. If the tread depth is below safe limits—or if you spot cracking, bulging, or dry rot on the sidewalls—it's time for a replacement. 

Don't wait until a tire blows on the freeway; preventative inspections save lives and money.

Use the Right Tires for the Job

Heavy haul trucking demands tires built for high heat and high load. Invest in tires rated for your typical weight class and road conditions. 

Summer-specific or heat-resistant tires are worth the investment if you're consistently operating in hot climates.

Have a Summer Tire Maintenance Routine

Create a daily and weekly tire maintenance schedule. Train your drivers to perform pre-trip and post-trip inspections, log any tire pressure changes, and report visible wear. Keep a tire repair kit onboard and make sure drivers know how to use it.

When it comes to summer blowouts, the best defense is a strong maintenance offense. By understanding the causes and staying proactive, you can keep your heavy haul fleet rolling safely all summer long.
