How to Change a Spare Wheel: A Step-by-Step Guide
Changing a spare wheel is one of the most practical skills a driver can have. A flat tire doesn't wait for convenient timing, and knowing how to swap in your spare — safely and correctly — can get you back on the road without a tow truck. The process is broadly the same across most passenger vehicles, but the details vary depending on your car, where your spare is stored, and what type of spare you're carrying.
What You'll Need Before You Start
Most vehicles come with the basic tools for a tire change stored with the spare. Before a flat happens, it's worth confirming you actually have:
- A spare tire (and that it's properly inflated)
- A jack (scissor jack or hydraulic floor jack)
- A lug wrench that fits your wheel's lug nuts
- The owner's manual (it shows correct jack placement points)
Optional but useful: wheel wedges or chocks, a flashlight, gloves, a rain poncho, and a reflective triangle or road flares.
Step 1: Get to a Safe Location
Pull as far off the road as possible — ideally onto a flat, stable surface away from traffic. Avoid soft ground, hills, or gravel if you can. Turn on your hazard lights immediately. If you have them, set out reflective triangles or flares behind the vehicle before doing anything else.
Apply the parking brake before you exit the vehicle.
Step 2: Loosen the Lug Nuts Before Jacking
This order matters. Loosen each lug nut before lifting the vehicle — while the tire is still on the ground and has resistance. Turn counterclockwise. Break them loose (about a half to full turn) but don't remove them yet.
If lug nuts are very tight, use your body weight on the wrench. Applying force to a raised vehicle can cause it to shift off the jack.
Step 3: Position the Jack Correctly ⚠️
This is where the owner's manual earns its keep. Every vehicle has designated jack points — reinforced areas of the frame where the jack can safely support the vehicle's weight. Using the wrong spot can damage the rocker panels, pinch welds, or undercarriage — and worse, cause the vehicle to fall.
Common jack point locations:
| Vehicle Type | Typical Jack Point Location |
|---|---|
| Sedans/Coupes | Reinforced notches along the frame rail behind the front wheels or ahead of the rear wheels |
| Trucks/SUVs | Frame rails or designated crossmembers |
| Unibody vehicles | Pinch welds (with an adapter) or specific frame locations |
Raise the vehicle until the flat tire clears the ground by a few inches — just enough to remove and replace it.
Step 4: Remove the Flat Tire
Finish removing the lug nuts completely. Keep them somewhere you won't lose them — a pocket or hub cap works well. Pull the flat tire straight toward you and set it aside (flat on the ground, out of your way).
Step 5: Mount the Spare
Lift the spare into position and align the holes with the wheel studs. Push it flush against the hub. Hand-tighten the lug nuts in a star or cross pattern — not in a circle — to ensure even seating. This pattern prevents warping.
Step 6: Lower the Vehicle and Fully Torque the Lug Nuts
Lower the jack until the tire contacts the ground but the vehicle's full weight isn't yet on it. Tighten the lug nuts further with the wrench, again using the star pattern. Then lower completely and remove the jack.
Once the vehicle is fully on the ground, go back over the lug nuts one more time to confirm they're as tight as you can get them with the wrench. If you have access to a torque wrench, your owner's manual will list the correct torque specification (typically between 80–120 ft-lbs for most passenger vehicles, though this varies).
Step 7: Check the Spare's Tire Pressure 🔧
Before driving, check the spare's inflation if at all possible. A TPMS (Tire Pressure Monitoring System) warning light may appear even after the swap — some systems reset automatically, others require a manual reset or brief drive.
Full-Size vs. Compact Spare: Know the Difference
How you drive on the spare depends heavily on which type you have.
| Spare Type | Speed Limit | Distance Limit | Notes |
|---|---|---|---|
| Full-size matching spare | Normal | Normal | Treats like a regular tire |
| Compact "donut" spare | Typically 50 mph max | Typically 50–70 miles max | Not for highway speeds or long hauls |
| Run-flat tire | Varies (check manual) | ~50 miles at reduced speed | No spare needed; still requires attention |
Compact spares are not meant for extended driving. They exist to get you to a tire shop — not to serve as a long-term replacement.
Where Spare Tires Are Stored
Under the vehicle: Common on trucks and larger SUVs. A cable-lowering mechanism releases it. This requires knowing how that system works — it's covered in the owner's manual.
In the trunk: Standard on sedans and most crossovers. Often under a floor panel, sometimes beneath cargo in an SUV.
On the rear exterior: Some SUVs and off-road vehicles mount the spare on the tailgate or rear bumper carrier.
Variables That Change the Process
- Alloy vs. steel wheels — alloy wheels can be heavier and may require more careful handling
- Locking lug nuts — require a special key socket, which should be stored with your tools
- EVs and hybrids — many don't include a spare at all; they may come with a tire inflation kit instead, which doesn't work on all types of damage
- AWD vehicles — some manufacturers have strict guidance about spare use in AWD systems, since a significant size mismatch between tires can stress the drivetrain
- Roadside conditions — nighttime, rain, or highway shoulders dramatically affect safety; sometimes calling for roadside assistance is the right call
The steps above apply broadly to most passenger vehicles, but your specific vehicle's jack points, torque specs, spare type, and storage location shape how this process actually plays out for you.
