The Fourth of July weekend is one of the busiest times of the year for hitting the road—especially if you’re towing a camper for a long holiday getaway. Before you load up and head out, it’s critical to inspect your tires for signs of trouble. One of the most dangerous and commonly overlooked tire issues? Bulges. These hidden hazards can lead to blowouts at highway speeds, putting your safety—and your holiday—at serious risk.
What Causes Tire Bulges?
Tire bulges are typically caused by internal damage to the tire’s structure. When the internal cords or sidewall plies break, air pressure forces the rubber to bubble outward. This is usually the result of hitting a pothole, curb, or debris at high speed. Once a bulge forms, the tire is no longer structurally sound and can fail without warning.
Where to Look for Bulges
Bulges most often appear on the tire’s sidewall but can also occur in the tread area. Do a full 360-degree visual inspection of each tire—on both your tow vehicle and your camper—before your trip. Run your hand slowly along the surface of the sidewall to feel for any raised areas, bubbles, or soft spots. If you find anything unusual, the tire should be replaced immediately.
Why They’re Extra Risky When Towing
When you tow a camper, your tires are under added stress from the extra weight and heat buildup during long highway drives. That extra load can cause a weak spot in the tire to give way suddenly, especially on hot pavement. A blowout while towing can lead to swaying, loss of control, or even a rollover—especially at freeway speeds.
Don’t Rely on Just a Quick Glance
Tire bulges don’t always jump out at you, especially if you’re in a rush. That’s why it’s worth taking a few extra minutes to perform a thorough pre-trip inspection. Also, check for uneven tread wear, embedded objects, and proper tire pressure using a reliable gauge.
Final Thoughts
Before you hook up your camper and head out for Fourth of July fun, give your tires a proper once-over. Spotting a bulge early can mean the difference between a safe trip and a roadside emergency. When in doubt, replace the tire—it’s a small price to pay for peace of mind and a smooth, safe holiday journey.
