Why Do Truck Tires Blow Out More in Hot Weather?

Have you ever seen pieces of torn truck tires on the road, especially in summer? These are called road gators, and they often come from tire blowouts.

When the weather gets hot, truck tires expand, and if they are not in good shape, they can explode while driving. This is dangerous for truckers and for other vehicles on the road.

Truck tire blowouts happen more in hot weather because high temperatures make the rubber softer, increase air pressure inside the tire, and weaken the tire’s structure.

If a truck driver is going fast or carrying a heavy load, the risk becomes even higher. A blowout can cause a truck to lose control, leading to accidents, damage, or delays in deliveries.

But the good news is that truckers and fleet owners can prevent tire blowouts with proper maintenance and smart driving habits.

In this blog, we will explain why truck tires fail in hot weather, the dangers of blowouts, and how to avoid them with simple steps.

Whether you’re a truck driver, fleet manager, or business owner, this guide will help you keep your truck tires safe on the road.

How Heat Affects Commercial Truck Tires

A. The Science Behind Heat and Tires

Heat and truck tires don’t mix well. When temperatures rise, truck tires absorb heat from the road, causing the rubber to soften.

This weakens the tread, casing, and sidewalls, making them more likely to fail under pressure.

Another big problem is air expansion. As the air inside the tire heats up, it expands, increasing the internal pressure.

If the tire is already old, worn out, or damaged, this extra pressure can push it past its limit, leading to a blowout.

Studies show that at 200°F, rubber starts breaking down. When this happens, the tire loses its strength and flexibility, making it more likely to crack or separate.

This also reduces fuel efficiency, as the truck has to work harder to move forward due to the increased rolling resistance.

B. Road & Environmental Heat Factors

It’s not just the weather—the road itself plays a huge role in tire overheating. On a 90°F day, asphalt can get as hot as 150°F, making the tires even hotter as they roll over it.

Long-haul driving without taking cooling breaks adds to the problem. The longer a truck runs, the more heat builds up in the tires, increasing the chance of tread separation or sidewall failure.

Another overlooked factor is direct sunlight. Parking a truck in the sun for hours before a trip can preheat the tires, making them weaker before even hitting the road.

Over time, UV exposure also dries out the rubber, causing cracks and faster deterioration.

The Dangers of Truck Tire Blowouts

Truck tire blowouts are more than just an inconvenience—they are serious safety hazards that can put lives at risk and lead to major financial losses.

Here’s why every trucker and fleet operator should take blowout prevention seriously.

A. Immediate Risks of a Blowout

A tire blowout can happen in seconds, but the damage it causes can last much longer.

• Loss of Control at High Speeds
  A sudden tire failure can make a truck swerve uncontrollably, especially if it happens on the steering axle. At highway speeds, this could lead to multi-vehicle accidents.
• Flying Tire Debris (“Road Gators”)
  When a truck tire explodes, pieces of rubber and metal can scatter across the road. These chunks, known as “road gators”, are dangerous obstacles for other drivers. Hitting them can blow out a car’s tires, damage undercarriages, or even cause crashes.
• Jackknifing or Rollovers
  If a blowout happens on a rear axle, it can cause the trailer to swing out of control, leading to a jackknife accident. In extreme cases, the sudden loss of balance can tip the truck over, causing a rollover crash.

B. Long-Term Consequences

Even if a blowout doesn’t cause an accident, it can still lead to major problems for truckers and fleet owners.

• Expensive Repairs & Increased Fuel Consumption
  When a truck loses a tire, it can damage the wheel, suspension, and nearby tires. The added strain on the engine also leads to higher fuel consumption due to increased rolling resistance.
• Delivery Delays & Profit Loss
  If a blowout happens in the middle of a trip, the truck has to stop for roadside assistance or a tire replacement. This means missed delivery deadlines, unhappy customers, and financial losses for trucking companies.
• Higher Maintenance Costs & DOT Fines
  The Department of Transportation (DOT) and Federal Motor Carrier Safety Administration (FMCSA) have strict tire maintenance rules. If an inspection finds worn-out or improperly maintained tires, trucking companies can face fines or even have their vehicles taken off the road.
• Insurance & Liability Risks
  If a blowout-related accident causes injuries or property damage, trucking companies could be sued for negligence. Insurance companies may raise premiums or even deny coverage if the company fails to follow proper tire safety measures.

Blowouts are dangerous, costly, and avoidable with proper maintenance and tire safety practices.

Main Causes of Heat-Related Tire Blowouts

Tire blowouts don’t just happen randomly—they are often caused by heat and stress that build up over time.

Understanding these factors can help truckers and fleet operators prevent dangerous and costly failures on the road.

A. Underinflated Tires (Biggest Risk Factor)

One of the biggest reasons truck tires fail in hot weather is underinflation.

• Low tire pressure increases friction, causing the rubber to heat up quickly.
• More contact with the road means extra stress on the tire, wearing it out faster.
• Higher rolling resistance makes the engine work harder, reducing fuel efficiency and increasing costs.
• According to a Tire Business study, about 90% of tire failures are linked to improper inflation.

Solution: Check tire pressure before every trip, especially during hot weather.

B. Overinflated Tires

While underinflation is a bigger problem, over inflation can also lead to blowouts.

• Too much air pressure causes localized overheating, making rubber brittle and more likely to crack.
• Weakened sidewalls can’t handle impacts from potholes or debris, increasing the risk of an explosion.
• Overinflated tires have less grip on the road, making trucks harder to control in rainy or slippery conditions.

Solution: Follow manufacturer-recommended PSI levels to keep tires at the right pressure.

C. Overloading and Load Imbalance

Carrying too much weight or loading cargo unevenly puts extra stress on tires.

• Exceeding weight limits forces tires to work harder, increasing heat buildup.
• Unevenly distributed cargo creates pressure points that can cause sidewall failure.
• Overloaded trucks struggle with braking, acceleration, and steering, making them harder to control if a tire fails.

Solution: Stick to FMCSA weight regulations and ensure proper weight distribution before every trip.

D. High Speeds & Aggressive Driving

The way a truck is driven also plays a role in tire overheating.

• Driving at high speeds causes tires to rotate faster, increasing friction and heat buildup.
• Sharp turns, sudden braking, and rapid acceleration put extra stress on the rubber.
• The faster a truck goes, the less time the tires have to cool down, leading to overheating.

Solution: Drive at safe, steady speeds and avoid harsh braking or acceleration, especially in hot weather.

Tires are a truck’s first line of defense on the road. Keeping them properly inflated, balanced, and maintained can prevent dangerous blowouts.

Preventing Truck Tire Blowouts in Hot Weather

Truckers and fleet managers can take proactive steps to prevent tire failures caused by extreme heat. Here’s how to keep commercial truck tires safe and durable in hot conditions.

A. Proper Inflation & Tire Monitoring

Keeping tires properly inflated is the best way to prevent blowouts.

• Check tire pressure before every trip when the tires are cool for an accurate reading.
• Use a Tire Pressure Monitoring System (TPMS) to track real-time pressure and temperature while driving.
• Best TPMS for fleets: The Doran 360™ TPMS sends warnings if tire temperatures exceed 175°F, helping drivers take action before a blowout occurs.
• Underinflated or overinflated tires increase rolling resistance, leading to higher fuel costs and faster wear.

Solution: Invest in high-quality TPMS and perform regular pressure checks before hitting the road.

B. Cooling & Protection Strategies

Extreme heat makes tires vulnerable, but a few cooling strategies can help:

• Take cooling breaks every 100 miles or every 2 hours to let tires rest.
• Park in shaded areas or use tire covers when stopping for long periods.
• Spraying water on overheated tires can quickly reduce surface temperature.
• Avoid driving on hot asphalt for extended periods—roads can reach up to 150°F on a 90°F day, worsening heat buildup.

Solution: Plan routes with rest stops and take breaks to prevent tires from overheating.

C. Choosing the Right Tires for Hot Weather

Not all truck tires handle heat the same way. Choosing the right type for hot conditions can reduce blowout risks.

• Heat-resistant tires from Michelin, Goodyear, and Bridgestone use advanced rubber compounds that resist high temperatures.
• Retreaded tires are more prone to heat damage—consider avoiding them in extreme summer conditions.
• Wide-base single tires have a larger contact patch, reducing heat buildup compared to dual tires.

Solution: Use premium heat-resistant tires in hot weather and avoid retreads when possible. Not all tires are built for extreme heat. Using heat-resistant tires from brands like Michelin, Goodyear, and Bridgestone can help reduce wear and blowout risks.

D. Regular Maintenance & Fleet Safety Measures

Routine tire maintenance is critical for truck safety.

• Inspect tires before and after every long-haul trip for cracks, bulges, or uneven wear.
• Rotate tires frequently to balance wear and prevent weak spots.
• Check tread depth—tires with worn-out treads heat up faster and lose traction.
• Follow FMCSA & DOT tire maintenance regulations to ensure compliance and safety.

Solution: Set up a routine tire inspection schedule to catch problems early.

E. Seasonal Tire Maintenance Plans

Many fleets adjust tire care based on seasonal temperature changes.

• Consider using heat-resistant summer tires in hot climates for better durability.
• Adjust tire pressure based on temperature—hot weather can increase air expansion, so monitor PSI levels regularly.
• Follow manufacturer guidelines for summer tire care to prevent premature wear.
• Another smart move is keeping a TruckClaws™ II Light Kit on hand. It can help truckers get out of dangerous situations after a blowout or when stuck on hot, loose surfaces.

Solution: Develop a seasonal maintenance plan to keep truck tires in peak condition year-round.

Heat is one of the biggest threats to commercial truck tires, but with the right strategies, truckers can avoid blowouts and keep their fleet safe.

The Role of Technology in Preventing Tire Failures

Modern technology helps truckers and fleet managers reduce the risk of tire blowouts caused by heat and other factors. Here’s how advanced systems can enhance tire safety and fleet efficiency.
