You should not “drive” on a flat tire at all—only creep the car a very short distance to get out of immediate danger, then stop. Continuing further very quickly risks losing control and destroying the wheel and suspension.

Quick Scoop

  • For a normal (non–run-flat) tire, aim for no more than a few hundred feet at walking-speed (under about 5 mph) just to reach a safe shoulder or parking spot.
  • Many tire and repair shops warn that once you go beyond roughly 50–100 feet , rim damage can begin, especially on rough pavement.
  • Some guides say that in an absolute emergency , you might stretch this to around 1–1.5 miles at very low speed (under about 20 mph) only to escape a dangerous location, but the tire will almost certainly be ruined and the wheel may be damaged.
  • Run‑flat tires are different : manufacturers often rate them for up to about 50 miles at up to around 50 mph , but only if they are true run‑flats and within their specific guidelines.

Why driving on a flat is so risky

  • The car becomes harder to control, especially in turns or emergency maneuvers, increasing crash risk.
  • The flat tire quickly overheats and shreds, then the metal rim hits the road , which can bend the wheel, damage brakes and suspension, and even cut into the bodywork.
  • At higher speeds (around 20–30 mph and above), rapid tire destruction and loss of control become much more likely, which is why most guides say “do not continue driving” except for a short crawl to safety.

What to do if you get a flat

  1. Stay calm, signal, and slow down gently. Avoid hard braking or sudden steering.
  1. Move only as far as needed to reach a safe spot off the live lane (shoulder, parking lot, exit), at very low speed.
  1. Stop, turn on hazard lights, and secure the car.
  2. If safe and you know how, install the spare or use an inflator/sealant if appropriate; otherwise, call roadside assistance or a tow.

Extra notes

  • Heavy vehicles (SUVs, trucks) should move even less distance on a flat (often quoted under about 100–200 feet at walking speed) because of higher load on the tire and rim.
  • In hot weather, rubber softens and heat builds faster, so safe distance shrinks; in cold weather you might technically limp a bit farther, but the risk is still high and not recommended except to escape immediate danger.

Bottom line: Treat a flat as an emergency: crawl a very short distance to a safe place, then stop and fix or tow the vehicle, rather than “driving” on it.
