When a tire blows, your instinct is to stomp the brake and yank the wheel. Don't. Keep a firm grip, stay in your lane, and let the vehicle slow down gradually. Many drivers even give a little gas for a moment to keep the car stable before easing off.
Once you're under control and slowing, signal and steer onto the shoulder, as far right as you safely can. On the I-10, an exit ramp or a wide pull-out is better than a narrow shoulder with semis passing a few feet away. Turn on your hazards immediately.
Stay in the vehicle with your seatbelt on if you're on a busy freeway shoulder. In summer, keep the engine running for air conditioning if it's safe to do so. Walking the shoulder in 115-degree heat is a real danger.
When you call, tell us three things: where you are (nearest exit, mile marker, or a dropped pin), what you're driving, and the tire size printed on the sidewall if you can safely see it. That lets us bring the right tire and give you an accurate price and arrival estimate on the first call.
