The answer: as little as possible.
Driving on a flat tire — even for a few hundred feet — can destroy the tire and seriously damage the wheel rim. For most vehicles, the practical answer is zero miles if you can avoid it. Keep reading to understand exactly what happens and what your options are.
It's one of the most common questions after a tire failure: how long can I drive on a flat tire to get to a shop? The instinct makes sense — driving feels easier than dealing with it on the side of the road. But the reality of what happens when you drive on a flat tire usually makes that decision far more expensive. Here's the full picture.
What Actually Happens When You Drive on a Flat Tire
A tire's job is to carry the vehicle's weight on a cushion of air. When that air is gone, the vehicle's weight is transferred directly to the tire's sidewall and then to the wheel rim. The sidewall is not designed to bear this load — it collapses and folds with every revolution.
The sidewall begins folding and creasing. The inner liner starts to tear. Tire still holds rough shape.
Significant sidewall damage occurs. The tire becomes unrepairable. The inner bead may start to separate from the rim.
The tire is typically shredded. The steel belts separate. The rim is now grinding on the road surface.
The wheel rim is heavily damaged or destroyed. Suspension components may be damaged. Vehicle control becomes dangerous.
The Real Cost of Driving on a Flat Tire
People drive on flat tires to avoid the inconvenience of stopping. Here's what that decision typically costs:
The math is straightforward: driving on a flat turns a potentially repairable tire into a destroyed tire, often plus a damaged rim. The "convenience" of driving to a shop typically costs $300–$1,000+ more than stopping immediately.
Exception: Run-Flat Tires
Run-flat tires are specially constructed with reinforced sidewalls that can support the vehicle's weight without air pressure — for a limited distance and speed. Most run-flat tire systems are rated for:
Important caveats about run-flat tires:
- Check your owner's manual — the specific mileage and speed limit varies by vehicle and tire brand
- Run-flat tires that have been driven flat are usually not repairable and must be replaced
- Not all vehicles have run-flat tires — most standard tires have zero run-flat capability
- Many EVs use run-flats because they have no spare tire — check your model
- Even run-flats should not be driven on longer than necessary — replace as soon as possible
What to Do Instead of Driving on a Flat
The best alternatives to driving on a flat tire, in order of preference:
Call mobile tire repair
A service comes to you — the tire is repaired or replaced on-site. You don't move the vehicle at all. This is the safest and often cheapest option.
See mobile tire repair →Change to your spare (if you have one)
If you have a full-size spare in good condition and you're in a safe location, changing the tire is a valid option. A donut spare should be driven no more than 50 miles at no more than 50 mph.
Drive slowly to a safe pullover spot
If you absolutely must move the vehicle (you're in a dangerous lane position), drive very slowly — under 5 mph — for the shortest possible distance to reach a shoulder or parking area.
Can You Drive on a Flat at Low Speed to Reach a Shop?
This is the most common rationalization — "I'll just go slow." The problem: even at 5 mph, every revolution of the tire folds the sidewall under the rim. Within half a mile, the sidewall is typically destroyed regardless of speed. Unless you are in immediate danger and need to move the vehicle to safety, the answer is to stop and call for emergency roadside tire repair rather than attempting to drive to a shop.
