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

Jump-start a dead battery safely
Jumper cables are simple until you hook them wrong. Do it right and you'll avoid sparks, ruined electronics, and a tow you didn't need.
What to do when stuck in sand or mud
Ocean Beach, Fiesta Island, and the Carrizo Badlands eat vehicles weekly. The first thing to do is stop making it worse.
Prepare your vehicle for a tow
A few minutes of prep before the tow truck arrives saves time, avoids damage, and makes the whole call go faster.
