Picture this: The windows are down, your favorite playlist is on, and miles of open road stretch out before you. It’s the perfect summer road trip. The last thing you want to interrupt this scene is the sudden, violent jolt and terrifying sound of a tire blowout.
Unfortunately, this dangerous scenario is far more common during the hot summer months. The combination of scorching asphalt and high speeds creates a perfect storm for tire failure. But here’s the good news: a tire blowout is almost always preventable.
This guide will walk you through seven simple, crucial steps you can take to protect your tires, your car, and your passengers. Consider this your ultimate checklist for summer driving safety, ensuring your only travel surprises are the good kind.
Why Summer Heat is a Tire’s Worst Enemy
Ever wonder why you see more tire debris on the side of the highway when the temperatures soar? It’s not a coincidence. It’s basic physics.
Heat is the number one enemy of a healthy tire. On a hot summer day, the asphalt can easily reach temperatures of 140°F (60°C) or higher. As your tires roll over this superheated surface, two things happen:
- Air Pressure Skyrockets: The air inside your tires expands when heated. This dramatically increases the internal tire pressure, pushing it far beyond the recommended safe level.
- Rubber Weakens: At the same time, the friction from driving generates even more internal heat. This extreme heat can break down the rubber compounds and the internal structure of the tire itself, especially if the tire is older, damaged, or underinflated.
This combination of soaring internal pressure and weakened rubber is the recipe for a catastrophic blowout.
Your 7-Point Summer Tire Safety Checklist
Think of these seven steps as a 5-minute pre-trip inspection that could save you hours of hassle—or even save your life.
1. Master Your Tire Pressure (The #1 Culprit)
If you only do one thing on this list, make it this. The leading cause of tire failure is not a puncture; it’s driving on underinflated tires. An underinflated tire flexes excessively, like bending a paperclip back and forth. This motion generates an incredible amount of internal heat, leading directly to a blowout.
How to Get it Right:
- Find the Magic Number: The correct tire pressure for your vehicle is not printed on the tire sidewall. That number is the tire’s maximum pressure. Your car’s specific, recommended pressure (PSI, or pounds per square inch) is on a sticker inside the driver’s side doorjamb.
- Check Them “Cold”: For an accurate reading, check your pressure in the morning before you’ve driven, or at least three hours after the car has been parked. Driving heats up the tires and will give you a falsely high reading.
- Use a Good Gauge: Don’t rely on the built-in gauges at gas station air pumps, which are often inaccurate. A quality pencil or digital tire pressure gauge is a small investment in your safety.
- Don’t Forget the Spare! Make sure your spare tire is also properly inflated. A flat spare is a useless spare.
Plan to check your tire pressure at least once a month and always before a long road trip.
2. Inspect Your Tread Depth
Your tire’s tread isn’t just for looks; it’s essential for gripping the road, especially in wet conditions. Worn tires are also more susceptible to punctures and have a harder time dissipating heat, increasing your blowout risk.
The Easy Penny Test:
This classic trick is a simple way to check your tread depth.
- Take a penny and place it with Lincoln’s head upside down in one of your tire’s main tread grooves.
- If you can see the top of Lincoln’s head, your tread is dangerously worn down (below 2/32 of an inch) and it’s time to buy new tires immediately.
- If part of his head is covered by the tread, you’re still in the safe zone.
Also, look for built-in tread wear indicator bars. These are small, raised bars of rubber that run across the grooves. When the tread wears down to become even with these bars, the tire is at the end of its legal and safe life.
3. Perform a Visual Inspection for Damage
Take a moment to walk around your car and really look at your tires. A quick visual inspection can reveal developing problems before they become full-blown emergencies on the highway.
What to Look For:
- Bulges or Blisters: A bulge on the sidewall looks like a bubble and indicates that the tire’s internal structure has been damaged and is weak. This is a blowout waiting to happen. Replace this tire immediately.
- Cracks and Cuts: Look for fine cracks in the sidewall, which is a sign of “dry rot” from age and sun exposure. Check for any deep cuts or scrapes that could compromise the tire’s integrity.
- Punctures: Scan the tread for any embedded objects like nails, screws, or glass. Even a slow leak from a small puncture can lead to underinflation and a subsequent blowout.
4. Don’t Overload Your Vehicle
Summer road trips often mean packing the car to the brim with luggage, coolers, camping gear, and people. But every vehicle has a maximum load capacity, and exceeding it puts enormous stress on your tires.
Overloading your car squashes the tires, forcing them to work harder and generate far more heat than they were designed for. Check the same sticker on your doorjamb that lists the tire pressure; it will also list the maximum vehicle load. Remember to factor in the weight of all passengers and all your cargo.
5. Rotate Your Tires Regularly
Your front and rear tires wear down at different rates. On most cars, the front tires bear the weight of the engine and handle the stress of steering, causing them to wear faster.
Rotating your tires—moving them to different positions on the car—promotes even tread wear. This not only extends the life of your tires, saving you money, but also ensures more balanced, predictable handling and reduces the risk of one tire failing prematurely. Check your owner’s manual, but a good rule of thumb is to have them rotated every 5,000 to 7,500 miles.
6. Check Your Tire’s Age
Did you know tires have an expiration date? The rubber compounds in a tire degrade over time due to exposure to oxygen and UV rays, even if the tire has plenty of tread left. An old, brittle tire is significantly more likely to fail in extreme summer heat.
How to Read Your Tire’s Birthday:
Look for the “DOT” code on the tire’s sidewall. It’s a series of letters and numbers. The last four digits tell you when the tire was made.
- For example, a code ending in “3221” means the tire was manufactured in the 32nd week of 2021.
Most auto and tire manufacturers recommend replacing tires once they are 6 to 10 years old, regardless of how much tread they have left.
7. Be Mindful of Your Driving Habits
Finally, how you drive has a direct impact on your tires.
- Speed: Driving at high speeds for extended periods generates a massive amount of friction and heat. Adhering to the speed limit isn’t just about avoiding a ticket; it’s about keeping your tires within their safe operating temperature.
- Road Hazards: Do your best to safely avoid potholes, curbs, and road debris. A hard impact can cause unseen internal damage to a tire’s belts or structure, creating a weak spot that can fail days or weeks later under the stress of highway driving.
What to Do If a Tire Blows Out Anyway
Even with perfect preparation, a blowout can still happen. Knowing how to react can be the difference between a scary moment and a tragic accident.
- DO NOT SLAM THE BRAKES. This is the most critical rule. Braking hard will further unbalance the vehicle and can cause you to lose control and spin out.
- Grip the Steering Wheel Firmly. Your car will pull hard toward the side of the blown tire. Use a firm, two-handed grip to keep the car pointed straight down your lane.
- Ease Off the Accelerator. Do not turn the engine off. Simply lift your foot off the gas pedal and allow the car to slow down on its own.
- Pull Over Safely. Once you’ve slowed to a manageable speed (around 30 mph or less), signal and carefully steer to a safe location on the shoulder of the road, as far from traffic as possible.
- Turn On Your Hazard Lights. Make your vehicle as visible as possible to other drivers before you attempt to assess the damage or call for help.

Your tires are the only thing connecting your vehicle to the road. Before you set out on your next summer adventure, take the five minutes required to walk around your car and give them the attention they deserve.
Remember the three most critical checks: Check Your Pressure, Inspect Your Tread, and Don’t Overload. It’s the simplest, most effective thing you can do to prevent a tire blowout and ensure you and your loved ones arrive at your destination safely. Happy travels
Frequently Asked Questions (FAQ)
Should I lower my tire pressure in the summer?
No, this is a dangerous myth. You should always inflate your tires to the vehicle manufacturer’s recommended “cold” pressure. While the pressure will rise as the tire heats up, engineers have already accounted for this. Underinflating a tire is the single biggest cause of heat buildup and blowouts.
Are certain tires better for preventing blowouts in the summer?
High-quality all-season or dedicated summer tires from reputable brands are designed with rubber compounds that perform better and are more durable in high temperatures. However, the most important factor is proper maintenance, regardless of the tire brand.
Can I feel a tire blowout coming?
Sometimes. Just before a tire fails, you might feel the steering get heavy or “sloppy,” or you might notice a growing vibration or shuddering through the car. If you feel anything unusual, don’t ignore it. Pull over as soon as it is safe and inspect all four tires.
