How to Change a Tire (Step-by-Step)

A flat tire is not a matter of if — it is a matter of when. Knowing how to change one is a fundamental driving skill that can save you hours of waiting for roadside assistance, especially in remote areas where cell service is unreliable.

This guide walks you through the entire process, from pulling over safely to torquing the lug nuts.

Key Takeaways

  • Every driver should practice changing a tire at home before they need to do it roadside.
  • Safety is the top priority — a well-lit, flat, stable surface away from traffic is essential.
  • The entire process takes 15-30 minutes once you have done it before.
  • Most modern cars come with a spare tire (compact or full-size), a jack, and a lug wrench — locate them before you need them.
  • Compact spare tires (“donuts”) are speed-limited (usually 50 mph) and distance-limited (50-70 miles).

What You Need

These items should already be in your car:

  • Spare tire (check its pressure regularly — a flat spare is useless)
  • Vehicle jack (the scissor jack that came with your car works; a hydraulic floor jack is better)
  • Lug wrench (the L-shaped or cross-shaped tool that fits your lug nuts)
  • Vehicle owner’s manual (shows jack placement points)

Helpful Additions

  • Flashlight or headlamp
  • Reflective triangles or flares
  • Gloves
  • Wheel chocks or a brick/rock
  • Rain jacket (flats do not wait for good weather)
  • Torque wrench (for proper final tightening)

Step-by-Step Process

Step 1: Pull Over Safely

  • Turn on your hazard lights immediately.
  • Slow down gradually and find a flat, stable surface away from traffic — a parking lot, wide shoulder, or rest area.
  • Avoid: Soft ground (jack will sink), hills (car may roll), curves (poor visibility for passing traffic), narrow shoulders.
  • If you cannot find a safe spot nearby, drive slowly on the flat tire to the next safe location. A damaged rim is better than being hit by traffic.

Step 2: Secure the Vehicle

  • Put the car in Park (automatic) or 1st gear (manual).
  • Engage the parking brake.
  • Place wheel chocks (or rocks, bricks, or a piece of wood) behind the tires diagonally opposite to the flat tire to prevent rolling.
  • Turn off the engine.
  • Set out reflective triangles or flares behind the car if on a roadside.

Step 3: Get Your Equipment Ready

  • Retrieve the spare tire, jack, and lug wrench from the trunk or under the vehicle.
  • Check your owner’s manual for the correct jack placement point — this is critical. Placing the jack incorrectly can damage the car or cause it to fall.

Step 4: Loosen the Lug Nuts (Before Jacking)

While the tire is still on the ground (for stability):

  1. Remove the hubcap or wheel cover if present.
  2. Using the lug wrench, loosen each lug nut by turning counterclockwise (lefty-loosey).
  3. Loosen them about half a turn — do not remove them yet.
  4. If a lug nut is stuck, use your body weight — stand on the wrench handle if necessary.

Important: Loosen in a star pattern (opposite nuts, not adjacent) to maintain even pressure.

Step 5: Jack Up the Vehicle

  1. Place the jack under the designated jack point (check your manual — usually a reinforced spot on the frame behind the front tire or in front of the rear tire).
  2. Raise the jack until the flat tire is approximately 6 inches off the ground.
  3. Never put any body part under the vehicle while it is on the jack.

Step 6: Remove the Flat Tire

  1. Finish unscrewing and remove all lug nuts. Place them in your pocket or a cup — losing one is a problem.
  2. Pull the flat tire straight toward you and off the hub.
  3. Set it flat on the ground nearby (slide it under the car as a safety backup if you want extra protection in case the jack fails).

Step 7: Mount the Spare Tire

  1. Lift the spare tire onto the hub, aligning the holes.
  2. Push it flush against the hub.
  3. Hand-tighten all lug nuts in a star pattern.
  4. Tighten them as much as you can by hand — the final torque happens on the ground.

Step 8: Lower the Vehicle

  1. Lower the jack slowly until the spare tire contacts the ground but the car’s full weight is not on it.
  2. Tighten the lug nuts firmly in a star pattern using the lug wrench. Use your body weight for leverage.
  3. Lower the jack completely and remove it.
  4. Give the lug nuts one more round of tightening.

Ideal torque: Check your manual for the recommended torque specification (typically 80-100 ft-lbs for passenger cars). If you have a torque wrench, use it. If not, tighten firmly — and visit a tire shop within 24 hours to verify torque.

Step 9: Clean Up and Check the Spare

  1. Stow the flat tire, jack, and lug wrench.
  2. Check the spare tire’s pressure — compact spares should be at 60 PSI (check the sidewall or manual).
  3. Remove wheel chocks and reflective triangles.
  4. Turn off hazard lights when safe to re-enter traffic.

Step 10: Drive to a Tire Shop

  • Compact spare (donut): Drive no faster than 50 mph and no farther than 50-70 miles. Get to a tire shop as soon as possible.
  • Full-size spare: You can drive normally, but verify lug nut torque at a shop within 50-100 miles.

What If You Do Not Have a Spare?

Some modern cars do not include spare tires. Instead, they may have:

  • Tire repair kit (sealant and compressor): Temporary fix for small punctures. Not effective for large tears or sidewall damage.
  • Run-flat tires: Can be driven for 50 miles at 50 mph after losing pressure, giving you time to reach a tire shop.

If your car has no spare and no run-flat capability, invest in a roadside assistance membership (AAA, your insurance company, or your manufacturer’s program).

When to Call for Help

Call roadside assistance or a tow truck if:

  • You are in an unsafe location (narrow highway shoulder, no visibility, heavy traffic)
  • You do not have a spare, jack, or lug wrench
  • The lug nuts are too tight to break loose
  • You have a physical limitation that prevents safe tire changing
  • The vehicle needs to be towed for other damage

Tire Maintenance to Prevent Flats

  • Check tire pressure monthly — the leading cause of tire failure is under-inflation
  • Inspect for damage — nails, screws, cuts, bulges
  • Rotate tires every 5,000-7,500 miles — see Car Maintenance Schedule: What to Do and When
  • Replace worn tires — tread below 2/32” is unsafe and illegal in most states
  • Avoid potholes and road debris when possible

Next Steps

  1. Practice at home — change a tire in your driveway before you need to do it roadside.
  2. Locate your spare, jack, and lug wrench right now. If you do not know where they are, check your manual.
  3. Check your spare’s pressure — a flat spare is useless. Check it every time you check your other tires.
  4. Add a flashlight and gloves to your car’s emergency kit.
  5. Learn to jump-start a car too — How to Jump-Start a Car (Step-by-Step).

Changing a tire is not glamorous, but it is empowering. Learn it, practice it, and file it away as one more skill that keeps you safe and self-sufficient on the road.
