A flat tire can leave you stranded beside fast traffic, in heavy rain, or on an unfamiliar road. Knowing how to change a tire on a car step by step can help you handle the problem safely and get moving again.
Start by finding a safe place to stop and securing the car. Then loosen the lug nuts, raise the vehicle at its approved jack point, and fit the spare as your owner’s manual directs. The manual takes priority because jack points, tools, spare-tire rules, and wheel fasteners vary by vehicle.
Get to a safe place before changing a tire
Move away from traffic before unloading tools
If the tire still holds air and the car responds normally, move to firm, level ground as far from traffic as possible. Avoid stopping on a narrow shoulder when you can reach a safer lot or turnout. If the car can’t be moved safely, don’t try to change the tire beside moving traffic; call roadside assistance or emergency services as needed.
Make the car visible and keep passengers clear
Turn on the hazard lights and set the parking brake. If passengers can exit safely, have them leave on the side away from traffic and wait well clear of the car. Set out reflective triangles or other warning devices only if you have them and can place them safely and lawfully.
Check the ground and conditions
Soft soil, a steep slope, ice, or an uneven shoulder can make a jack slip or sink. Poor visibility, strong wind, and passing traffic can also make the work unsafe. If the car can’t sit on firm, level ground, wait for help instead of lifting it.
Gather tools and secure the car
Find the spare, jack, and lug wrench
Check the trunk, cargo area, or under-floor compartment for the spare tire, jack, and lug wrench. Storage spots vary, so use the owner’s manual if you can’t find them. Some wheels have a locking lug nut that requires a special key; a flashlight and gloves can also help.
Confirm the spare is suitable
Check that the spare is the correct type for your car and has no visible damage. Temporary spares often have speed and distance limits printed on the tire or listed in the manual. Follow those limits, and don’t fit a spare that looks damaged or won’t seat properly.
Chock the wheels and loosen the lug nuts
Put an automatic car in Park. For a manual transmission, select a gear, then set the parking brake. Use wheel chocks if you have them, placing them against a wheel that stays on the ground.
While the flat tire is still on the ground, turn each lug nut counterclockwise to loosen it slightly. Use the lug wrench and steady pressure; don’t remove the nuts yet. If a nut won’t budge or the wrench slips, stop rather than risk injury.
How to change a tire on a car step by step
Locate the approved jack point
Find the jack point in your owner’s manual or look for the lifting marks on the vehicle. Jack placement differs by model, so don’t guess. For an electric vehicle, use only the listed lift points and keep the jack clear of the battery pack and other underbody parts.
Raise the car slowly
Place the jack on firm, level ground and position it at the approved point. Raise the car slowly until the flat tire clears the ground. Stop if the jack tilts, sinks, or shifts; lower the car if you can do so safely and call for help. Never put any part of your body under a car held up only by a jack.
Remove the flat tire
Finish unscrewing the lug nuts and keep them together where they won’t roll away. Pull the wheel straight off the hub. Check the mounting area for obvious dirt or damage, but don’t touch hot parts or try repairs beyond changing the wheel.
Fit the spare and tighten the wheel
Place the spare onto the wheel studs
Line up the spare’s holes with the wheel studs, then push it into place. If the wheel won’t sit flat, check the alignment and consult the manual if the wheel or fastener setup is unfamiliar. Don’t force it.
Hand-tighten the lug nuts in a star pattern
Start each lug nut by hand to reduce the chance of cross-threading. Tighten them until they hold the wheel in place, then work across the wheel in a crisscross or star pattern. This helps the wheel sit evenly against the hub.
Lower the car and tighten to the correct torque
Lower the car until the spare touches the ground and can’t spin freely. Tighten the lug nuts in the same pattern, using the torque value in the owner’s manual. A torque wrench helps you meet that specification; don’t guess at the amount of force.
Check the spare before you drive
Check the wheel, tools, and tire pressure
Make sure all lug nuts are in place and tightened, and check that the spare sits flat against the hub. Remove the jack and tools from around the car before driving. Use a tire gauge to check the spare’s pressure when possible, following the manual or the tire markings.
Drive within the spare’s limits
A temporary spare can affect how the car handles and brakes. Follow its stated speed and distance limits, and avoid extra trips. Drive to a tire shop or service center as soon as you can.
Arrange a repair or replacement
Have a tire professional inspect the flat tire to see if it can be repaired. Replace it if the damage makes repair unsafe. Recheck lug-nut torque after driving only if the vehicle maker or service professional recommends it.

Conclusion
To change a tire safely, move away from traffic, secure the car, loosen the lug nuts, and lift only at the approved jack point. Fit the spare, tighten the wheel to the maker’s specification, and follow the spare’s limits. If the location, ground, tools, or instructions make the job uncertain, call for help rather than risk a roadside change.
Before your next trip, check where your spare and tools are, then read the tire-changing instructions in your owner’s manual. That small bit of prep can make a flat easier to handle.
