How to Change a Flat Tire (Step by Step, Safely)

"How to change a tire" is searched roughly 350,000 times a month in the US — and unlike most searches on this list, a good chunk of those people are standing on the side of a road right now. Here's the safe, correct process, in the right order.

⚠️ Safety first. If you're on a busy highway shoulder, in bad weather, or somewhere that doesn't feel safe, call roadside assistance instead. A flat tire is annoying; a car changing a tire two feet from traffic is dangerous. This guide is for a safe, flat, off-traffic spot.

Before you touch the jack

  1. Pull well off the road onto flat, level, stable ground — a parking lot beats a highway shoulder every time.
  2. Turn on your hazard lights. Set the parking brake, and put an automatic in Park (or a manual in first gear/reverse).
  3. Chock the wheels if you have wedges — place them against the tire diagonally opposite the flat, so the car can't roll.

What you'll need

The spare tire, jack, and lug wrench that came with the car (usually under the trunk floor or in a side panel), plus your owner's manual — it shows the exact jack points for your specific model, which matter more than people think.

The 8 steps, in the order that actually works

  1. Loosen the lug nuts first — while the tire is still on the ground. Turn counter-clockwise about a quarter turn each, just to break them loose. Don't remove them yet; the tire's weight on the ground keeps the wheel from spinning while you do this.
  2. Position the jack at the correct point. Check your owner's manual — it's usually a reinforced spot on the frame near the flat tire, not just anywhere under the car.
  3. Raise the car until the flat tire is a few inches off the ground — enough to slide the tire off freely.
  4. Finish removing the lug nuts, then pull the flat tire straight off toward you.
  5. Mount the spare onto the wheel bolts, lining up the holes.
  6. Hand-tighten the lug nuts in a star pattern — not around in a circle. Tightening opposite nuts in sequence seats the wheel evenly instead of pulling it crooked.
  7. Lower the car until the tire just touches the ground (still not fully weighted), then fully tighten each lug nut, still in that same star pattern, as tight as you safely can with the wrench.
  8. Lower the car the rest of the way, remove the jack, and do one final check that every lug nut is tight.
💡 Why the star pattern matters: tightening lug nuts in a circle can pull the wheel on at a slight angle, which can cause vibration or, in bad cases, work the nuts loose over time. Opposite-corner order pulls it on flat and even.

Now that you're rolling again

Most compact "donut" spares are limited to about 50 mph and 50–70 miles — they're a get-you-to-a-shop tool, not a replacement tire. Check the spare's printed pressure (it's often higher than your regular tires) and get the flat repaired or replaced as soon as you reasonably can.

If this flat has you eyeing a newer, more reliable car, running the real numbers first is worth five minutes — try the auto loan calculator to see an actual monthly payment before you shop.

Key takeawayLoosen lug nuts before you jack the car up, jack at the reinforced point from your manual, and tighten everything back down in a star pattern — both hand-tight and final-tight. That order is what actually keeps you safe.

Frequently asked questions

Do I loosen the lug nuts before or after jacking up the car?

Before. Break them loose about a quarter turn while the tire is still on the ground — the car's weight keeps the wheel from spinning. Fully remove them only after the car is jacked up.

What pattern should I use to tighten lug nuts?

A star or criss-cross pattern — tighten one, then the one roughly opposite it, and so on. This seats the wheel evenly. Tightening them in a circle can pull the wheel on crooked.

How fast and how far can I drive on a spare tire?

Most compact spare ('donut') tires are rated for about 50 mph and 50-70 miles. They're meant to get you to a repair shop, not to be driven on long-term.

Where exactly should I place the jack?

At the reinforced jack point specified in your vehicle's owner's manual, near the tire you're changing — not just anywhere under the car's frame or plastic underbody panels.
