What to Do When You Get a Flat Tire on the Highway

Getting a flat tire on the highway is stressful and potentially dangerous. NHTSA reports that approximately 11,000 tire-related crashes occur annually in the United States, and flat tires contribute to roughly 78,000 accidents per year, especially on busy corridors like I-80 or I-380 in Eastern Iowa. The most important thing is to stay safe. IC Roadside & Key provides 24/7 flat tire assistance across Iowa City, Cedar Rapids, and all of Eastern Iowa. If you are on the highway right now with a flat, call (319) 963-2108 immediately.

Step 1: Get Off the Road Safely

As soon as you realize you have a flat, do not slam the brakes. Instead:

• Grip the steering wheel firmly and gradually reduce your speed. NHTSA advises against sudden braking, which can cause loss of control.
• Turn on your hazard lights immediately.
• Scan for a safe place to pull over. A wide shoulder, a rest area, or an exit ramp is ideal.
• On I-80 between Iowa City and the Quad Cities, exits can be far apart. Aim for the widest shoulder you can find.
• Never stop in the left lane, on a curve, or just over a hill where drivers behind you cannot see your vehicle.

Step 2: Make Yourself Visible

Once you are stopped and off the road as far as possible:

• Keep your hazard lights on.
• Place reflective triangles or flares at least 50 feet behind your vehicle, farther on highways where traffic moves fast.
• If it is dark, turn on your interior dome light so other drivers can see you are there.
• Wear a reflective vest if you have one. Iowa highways see heavy truck traffic, and visibility is critical. The Iowa DOT reports that I-80 through Johnson County carries over 30,000 vehicles daily, so being visible on the shoulder is essential.

Step 3: Decide Whether to Change It Yourself

Changing a tire on a highway shoulder is risky. Consider these factors:

• Traffic speed and volume — If vehicles are passing at 70 mph just feet away, it may be safer to call for help.
• Surface conditions — Soft ground, slopes, or gravel can cause a jack to slip. A flat, paved surface is essential.
• Weather — Rain, snow, or ice make highway tire changes extremely dangerous. Iowa winters are no time to be crouching on a highway shoulder.
• Your comfort level — If you have never changed a tire before, the highway shoulder is not the place to learn.

Step 4: Changing the Tire (If Safe to Do So)

If conditions are safe and you are confident:

• Apply the parking brake and place a wheel chock (or a rock) behind the opposite tire.
• Loosen the lug nuts slightly before jacking up the vehicle.
• Place the jack on a solid frame point as indicated in your owner's manual.
• Raise the vehicle, remove the lug nuts, swap the flat for the spare, and tighten the lug nuts in a star pattern.
• Lower the vehicle and tighten the lug nuts fully. Drive on the spare at reduced speed (usually under 50 mph) and replace it as soon as possible.
