Flat Tire or Blowout: Safe Steps, Repair Limits & Tire-Pressure Checks

If a tire blows out while driving

NHTSA advises keeping both hands on the steering wheel, avoiding abrupt braking or throttle reactions, stabilizing the vehicle and easing off the accelerator gradually. Move away from moving traffic only once controlled and safe.

Get to a safe stopping place. A full loss of pressure, damaged sidewall, exposed cords or unstable wheel is not a reason to continue driving at normal speed.

• Keep steering movements smooth as you regain control.
• Ease off the accelerator rather than slamming the brakes.
• Once stable, slow down and pull off the road when safe.
• Call for assistance if the stopping place exposes you to traffic.

Slow leak versus sudden blowout

If a tire is slowly losing pressure, inspect only from a safe stationary location. Locate the cold tire inflation specification on the driver's-door placard or vehicle manual, not the tire's maximum sidewall pressure.

If the tire is flat, repeatedly losing air, visibly torn or damaged, do not assume inflating it makes it roadworthy. Follow the manufacturer guidance for a spare or repair kit only where the exact equipment and safe working area allow.

Can a punctured tire be repaired?

NHTSA describes proper puncture repair as an inside patch plus a plug after demounting and inspecting the tire. Sidewall punctures are not repairable. A temporary external string plug alone is not a complete permanent repair under that guidance.

A tire technician must assess puncture location, size and damage; CarFactBook cannot authorize a repair from a photo or pressure reading.
