Change a flat tire on the side of the road

The difference between a 20-minute shoulder stop and an hour on the phone with a tow company is knowing where the spare and jack live before you need them.

What you'll learn

  • Why the traffic-side of a vehicle is the dangerous side for a DIY change
  • Where the jack point is on most modern vehicles (check the owner's manual)
  • The correct lug-nut loosening pattern (star/cross, not circle)
  • When to call for a tow instead - freeway shoulders, curbs without room, or damaged sidewalls

Step by step

  1. Pull off into a safe flat spot - away from traffic, off a shoulder if possible.
  2. Set the parking brake. Turn on hazard lights. Put the transmission in park (or 1st gear on manual).
  3. Loosen the lug nuts half a turn each before jacking - while the tire is still on the ground.
  4. Position the jack at the factory jack point under the frame. Raise until the tire is 1-2 inches off the ground.
  5. Remove the lugs, swap the flat for the spare, hand-tighten lugs in a star pattern.
  6. Lower the car fully. Torque the lugs in the same star pattern.
  7. Drive directly to a tire shop. Most spares are rated for 50 mph max, 70 mile range.
Safety note

If you are on the shoulder of I-5, I-15, I-8, or any busy freeway, call for a tow to a safe lot. Tire changes on active freeway shoulders cause hundreds of secondary accidents every year.
