How to Change a Flat Tire Step-by-Step
78% of drivers don't know how to change a flat tire. When it happens on the side of a highway, knowing this skill saves you $150-300 for a tow truck and hours of waiting. Here's the exact process, step by step.
What You Need (Check Your Trunk Now)
- Spare tire: Full-size or donut (compact spare " — limited to 50 mph)
- Jack: Usually stored under the trunk floor
- Lug wrench: Cross-shaped or L-shaped (comes with the car)
- Vehicle owner's manual: Shows proper jack placement
- Optional but recommended: Flashlight, gloves, reflective triangles, rain poncho
Step-by-Step Process
Step 1: Pull Over Safely (2 minutes)
- Pull as far right as possible onto a flat, stable surface
- Turn on hazard lights immediately
- Apply parking brake
- Place wheel wedges, rocks, or bricks behind the opposite tires to prevent rolling
Step 2: Loosen Lug Nuts (2 minutes)
Do this BEFORE jacking up the car. Use the lug wrench to loosen each lug nut 1/2 turn counterclockwise. If they're tight, use your body weight by stepping on the wrench. Don't remove them completely yet.
Step 3: Position the Jack (2 minutes)
Place the jack under the vehicle's frame at the correct jack point. Check your owner's manual for the exact location " — it's usually near the flat tire on the metal frame. Never place a jack on plastic body panels or the differential.
Step 4: Raise the Vehicle (3 minutes)
Jack up the car until the flat tire is 6 inches off the ground. Ensure the jack is stable and the car isn't wobbling. If the ground is soft, place a flat board under the jack for stability.
Step 5: Remove the Flat Tire (3 minutes)
Finish removing the lug nuts (they should come off easily now). Pull the flat tire straight toward you to remove it from the wheel studs. Set it flat on the ground under the car as a safety backup.
Step 6: Mount the Spare Tire (3 minutes)
Lift the spare tire onto the wheel studs. Align the holes and push it on. Hand-tighten the lug nuts in a star pattern (not circular) to ensure even pressure.
Step 7: Lower and Tighten (3 minutes)
Lower the jack until the tire touches the ground but the car's full weight isn't on it. Tighten the lug nuts in a star pattern with the wrench. Lower completely, then give each lug nut a final strong tighten. Remove the jack.
- Never get under the car when it's on a jack " — jacks can fail
- Don't drive on a donut spare faster than 50 mph or for more than 70 miles
- Get the flat tire repaired or replaced immediately " — donut spares are temporary
- If you're on a busy highway with no shoulder, call roadside assistance instead
