> **Quick Answer:** Pull off the freeway completely, get as far onto the shoulder or an exit ramp as possible, and turn on your hazards. Without a spare, your options are: run the tire on a run-flat if your car has them (up to 50 miles at 50 mph max), use a can of tire inflator foam for small punctures, call roadside assistance, or call a tow truck. Do not drive on a flat rim.
## What Are My Actual Options If I Have a Flat Tire and No Spare?
You have four realistic options, and which one applies depends on your car and the tire damage.
**Run-flat tires.** If your car came with run-flats (common on BMW, Mini, and some Mercedes models), you can drive on a flat for roughly 50 miles at no more than 50 mph. The sidewall is reinforced to hold the car up without air pressure. Check your dash for a TPMS warning and look up your specific model's run-flat range in the owner's manual before you go anywhere.
**Tire inflator foam (aerosol sealant).** Cans like Slime or Fix-a-Flat work only on small tread punctures, nothing in the sidewall, nothing larger than about a quarter-inch. Screw it onto the valve stem, fill the tire, and drive slowly to the nearest tire shop. Know that these cans can coat the inside of the wheel, which can cause vibration and may complicate the shop's repair.
**Roadside assistance tire service.** If you have AAA, a credit card with roadside benefits, or a manufacturer's roadside program (Ford Roadside, GM's Roadside Assistance, etc.), call them. A technician will come out with a replacement tire or bring a temporary spare and mount it on the spot. This is the cleanest option if you have it.
**Tow truck.** If the tire is shredded, the rim is damaged, or you have none of the above, call a tow. Driving on a flat rim will destroy the rim and can damage the wheel well, the brake caliper, and the suspension. A tow is far cheaper than that repair bill.
## How Do I Stay Safe on the Freeway While I Wait?
Get as far off the travel lanes as you physically can. That means pulling past the white fog line onto the shoulder, ideally around a curve or past an on-ramp where other drivers have more visibility. If you can reach an exit ramp, do it, even on a flat, at low speed. A damaged tire is cheaper than getting rear-ended.
Once stopped: hazards on, engine off if it is safe to do so, and if you have emergency triangles or flares, place them at least 200 feet behind the car. The closer you are to a high-speed lane, the more important it is to get out of the car and stand behind the guardrail. Do not stand between your car and traffic.

## Will Roadside Assistance Cover a Flat Tire If I Have No Spare?
Most roadside assistance plans cover tire service, but what they actually do varies. AAA will bring a spare if you have one or tow you to a tire shop if you do not. Manufacturer programs often do t

he same. Credit card roadside assistance typically dispatches a service truck and covers the labor, not the cost of a new tire.
If you have State Farm or USAA, your roadside add-on almost certainly covers a tow to the nearest tire shop. [Does USAA Roadside Assistance Cover Towing Cost](/does-usaa-roadside-assistance-cover-towing-cost/) breaks down exactly what that looks like. Read your policy before assuming a new tire is included because it usually is not.
## What Will a Tow Cost If I'm on the Freeway With No Spare?
A local tow from the freeway to the nearest tire shop typically runs $75 to $125 for the hook-up fee plus $3 to $7 per mile after the first few miles. If you are 10 miles from a shop, expect to pay roughly $100 to $175 out of pocket without a roadside plan. Flatbed tows cost more than wheel-lift, but most shops can handle either for a passenger car with a flat.
If the blowout also damaged the rim or suspension (common when a tire shreds at highway speed), [Tire Blew Out and Spare Isn't Safe: What Towing Will Cost You](/tire-blew-out-spare-tire-not-safe-to-drive-to-mechanic-towing-cost/) has a detailed breakdown of what that kind of tow looks like and what to expect at the shop.

## Common Questions
**Q: Can I drive on a flat tire for a short distance to get off the freeway?**
A: A hundred feet to reach the shoulder or an exit, yes. More than that and you risk shredding the tire completely and damaging the rim, which turns a $150 repair into a $400 one. Keep speed under 15 mph and get off the travel lane immediately.
**Q: Will Fix-a-Flat or Slime work on a freeway blowout?**
A: Usually not. A blowout typically involves sidewall failure or a large tear, neither of which aerosol foam can seal. Foam only works on small tread punctures. If the tire is visibly shredded or flat to the rim, skip the foam and call for help.
**Q: Does my car have run-flat tires and how do I know?**
A: Check the sidewall for the letters "ROF" (Run On Flat), "RFT", "SSR", or "ZP" (Zero Pressure). Your owner's manual will confirm it. Run-flats are common on BMWs, some Minis, and certain Lexus and Mercedes models that were sold without a spare from the factory.
**Q: How long will it take for a roadside assistance truck to reach me on a freeway?**
A: Response times vary by location and time of day. In a metro area, expect 30 to 60 minutes. On a rural stretch of interstate, it can be 90 minutes or longer. Give the dispatcher your exact mile marker or nearest exit number so they can find you fast.
**Q: Should I call 911 if I have a flat on the freeway?**
A: Only if you are in immediate danger, such as partially in a travel lane, injured, or unable to safely exit the vehicle. Otherwise, call your roadside assistance provider or a tow company directly. 911 is for emergencies, not flat tires. State police may stop to check on you regardless.
