How to Get a Spare Tire From Under the Car Safely

A flat tire can be a significant inconvenience, but knowing how to get a spare tire from under the car is a crucial skill for any driver. While many modern vehicles store spares in the trunk, some trucks, SUVs, and older cars keep them securely mounted underneath. This guide will provide a comprehensive, step-by-step process to safely and efficiently retrieve your spare tire, ensuring you’re prepared for unexpected roadside emergencies and can get back on the road with confidence.

Essential Preparations and Safety First

Before attempting to retrieve an under-mounted spare tire, adequate preparation is paramount. Rushing into the process without the right tools or without prioritizing safety can lead to injury or further vehicle damage. Taking a few moments to gather necessary items and establish a safe working environment will save time and prevent potential hazards.

Gathering Your Tools

Most vehicles come equipped with the basic tools required for a tire change, typically found in the trunk or under the rear seats. However, for a spare tire located under the car, you might need a few specific items or additional gear. Here’s a list of what you should have on hand:

Owner’s Manual: This is your primary resource. It provides exact instructions, diagrams, and specific locations for your vehicle’s spare tire and the tools needed to lower it. Every car’s mechanism can differ slightly, so this is invaluable.
Lug Wrench: Used to loosen and tighten lug nuts, and often to operate the spare tire lowering mechanism. Ensure it fits your vehicle’s lug nuts and the lowering crank.
Jack: While not directly used for lowering the spare, a jack is essential for raising the vehicle to change the flat tire once the spare is retrieved.
Jack Handle/Crank Rod: This often works in conjunction with the lug wrench or separately to operate the jack and, in some cases, the spare tire lowering mechanism.
Wheel Chocks: These are crucial for preventing the vehicle from rolling while you’re working underneath it. If you don’t have dedicated chocks, sturdy bricks or blocks of wood can serve as an alternative.
Gloves: Protect your hands from dirt, grime, and potential sharp edges.
Flashlight or Headlamp: Essential for visibility, especially if you’re working in low light conditions or at night, as the underside of a car can be dark.
Emergency Reflective Triangle or Flares: To warn other motorists of your presence, particularly if you’re on the side of a road.
Work Mat or Old Cardboard: To lie on, keeping you cleaner and more comfortable when working on the ground.
Penetrating Oil (Optional but Recommended): If the lowering mechanism is rusty or seized, a penetrating lubricant can be a lifesaver.

Prioritizing Safety Measures

Safety cannot be overstated when working around a vehicle, especially when retrieving an under-mounted spare. Always adhere to these safety guidelines:

Find a Safe Location: Pull over to a flat, stable, and solid surface away from traffic. Avoid soft ground, hills, or busy highways. If you must stop on a slight incline, make sure the vehicle is as stable as possible.
Engage the Parking Brake: This is a non-negotiable step. The parking brake prevents the vehicle from rolling unexpectedly.
Turn on Hazard Lights: Alert other drivers to your stopped vehicle, especially in low visibility conditions.
Use Wheel Chocks: Place chocks on the wheels diagonally opposite to the flat tire (e.g., if the front-right tire is flat, chock the rear-left wheel). If you’re only retrieving the spare and not changing the tire immediately, chock a wheel that won’t be lifted.
Secure the Vehicle: Ensure the car is stable and won’t shift. If you have passengers, it’s safer for them to exit the vehicle and wait in a safe location away from traffic.
Never Go Under a Vehicle Supported Only by a Jack: While retrieving the spare might require reaching under, never place your entire body under a vehicle that is only supported by a jack. For this task, the vehicle remains on its wheels until the flat tire needs changing.

Locating and Understanding Your Under-Car Spare Tire Mechanism

Knowing where your spare tire is and how its particular lowering system works is key to successfully completing the task. There’s no universal standard, so familiarity with your specific vehicle is crucial. This is where your owner’s manual becomes your best friend.

Common Spare Tire Locations

Under-car spare tires are typically found in one of two primary locations:

Under the Rear Bumper/Trunk Area: This is the most common spot for trucks, SUVs, and some minivans. The tire is usually secured in a cradle or basket by a cable or chain system.
Mid-Chassis: Less common, but some larger vehicles might have the spare mounted further forward, beneath the passenger compartment.

Always refer to your owner’s manual for the exact location and specific instructions for your vehicle model. It will also show you where the access point for the lowering mechanism is.

Identifying the Lowering Mechanism

The mechanism used to lower the spare tire from under the car is typically a crank system. This system usually consists of:

An Access Point: This is where you insert your lug wrench or special tool. It’s often a small hole or cap in the rear bumper, tailgate jamb, or even inside the trunk under a floor mat.
A Crank Rod/Tool: This is usually part of your vehicle’s standard tool kit. It’s designed to fit into the access point and connect to the lowering assembly.
A Cable or Chain Assembly: This runs from the crank mechanism to the tire cradle, supporting the spare tire. When you turn the crank, the cable/chain unwinds, slowly lowering the tire.

It’s vital to identify the correct access point and understand how your vehicle’s specific system operates before proceeding. Some newer vehicles might have a different type of release, but the crank system remains prevalent.

Step-by-Step Guide: Safely Lowering the Spare Tire

With preparations complete and the mechanism understood, you can now proceed with the actual process of how to get a spare tire from under the car. Follow these steps meticulously to ensure a smooth and safe retrieval.

Accessing the Crank Assembly

Locate the Access Point: As described above, consult your owner’s manual to find the precise location for inserting the crank tool. It might be behind a small plastic cover that needs to be popped off, or a clear opening.
Insert the Crank Rod/Tool: Insert the pointed end of the special crank rod or the lug wrench (as specified by your manual) into the access hole. You might need to wiggle it around a bit to ensure it properly engages with the winding mechanism inside. You should feel it click or seat securely.
Attach the Lug Wrench (if applicable): For many vehicles, the lug wrench serves as the handle for the crank rod. Attach it firmly to the exposed end of the crank rod, creating a lever for turning.

Engaging and Turning the Crank

Turn Counter-Clockwise: Once the tools are correctly assembled, begin to turn the lug wrench (or crank handle) counter-clockwise. This action will start unwinding the cable or chain, gradually lowering the spare tire.
Observe the Tire: As you turn, keep an eye on the spare tire underneath the vehicle. It should begin to descend slowly and steadily. If it doesn’t move or if you encounter significant resistance, stop and re-check your setup and the owner’s manual. Do not force it, as you could damage the mechanism.
Continue Lowering: Continue turning until the tire is fully on the ground and there’s enough slack in the cable/chain to easily maneuver the tire out.

Carefully Retrieving the Tire

Pull Out the Tire: Once the tire is on the ground, carefully slide it out from under the vehicle. You may need to tilt it or pull it at an angle to clear any obstacles.
Disconnect the Retainer Plate: The cable or chain usually has a retainer plate or a hook at its end that secures the tire in place. Once the tire is clear, you will need to manipulate the retainer plate through the center hole of the rim to detach the tire from the lowering mechanism. This usually involves tilting the plate and pulling it through.
Store the Lowering Assembly: Once the spare tire is free, you can crank the cable/chain assembly back up partially to keep it from dragging on the ground, or simply ensure it’s not obstructing anything. Do not crank it all the way up without the tire, as the cable could get tangled.

Congratulations! You have successfully learned how to get a spare tire from under the car. Now you can proceed with changing your flat tire.

What to Do After Retrieving the Spare Tire

Retrieving the spare is only half the battle. There are important considerations regarding the spare tire itself and what to do with your flat tire.

Checking the Spare Tire’s Condition

Before installing the spare, always perform a quick inspection:

Tire Pressure: Spare tires, especially “donut” or temporary spares, are often neglected. Check the inflation pressure. If it’s too low, you risk instability and further damage. Many temporary spares require a much higher pressure than regular tires (e.g., 60 psi). The correct pressure is usually listed on the tire’s sidewall or in your owner’s manual.
Visual Inspection: Look for any cracks, bulges, or excessive wear. A spare tire, even unused, can degrade over time. If it looks compromised, it might not be safe to use.

Proper Storage of the Flat Tire

Once you’ve installed the spare tire, you’ll need to deal with the flat one.

In the Original Spare Location: If your vehicle normally carries the spare under the car, you can usually use the same lowering mechanism to crank the flat tire back into place. This keeps it secure and out of the way.
In the Trunk: If the under-car spot is too dirty or the flat tire is heavily damaged, you might need to place it in the trunk. Be mindful of space and potential dirt.
Secure It: Wherever you put it, ensure the flat tire is securely stowed so it doesn’t roll around and become a projectile during driving.

Remember that a flat tire should be repaired or replaced by a professional as soon as possible. Temporary spares are not designed for long-term use or high speeds.

Common Challenges and Troubleshooting Tips

Even with the correct procedure, you might encounter some common issues when trying to retrieve an under-mounted spare tire. Knowing how to get a spare tire from under the car sometimes means knowing how to troubleshoot problems.

Dealing with a Stuck or Corroded Mechanism

Over time, exposed to road grime, salt, and weather, the spare tire lowering mechanism can become corroded or seized.

Apply Penetrating Oil: If the crank is stiff or won’t turn, generously spray penetrating oil (like WD-40 or similar) onto the mechanism, especially where the cable enters the housing. Let it sit for 10-15 minutes to penetrate.
Gentle Force and Wiggling: Try to turn the crank again, applying steady, firm pressure. You might need to rock the vehicle gently or tap the tire cradle with a rubber mallet (if accessible and safe) to dislodge it.
Inspect the Cable: Look for kinks or damage in the visible portion of the cable. A damaged cable will not operate correctly.

If the Tire Won’t Slide Out

Sometimes, even after fully lowered, the tire might be stuck.

Obstructions: Check for any debris, rocks, or vehicle components (like exhaust pipes) that might be trapping the tire.
Mud/Debris: If the vehicle has been off-road, mud or other debris can create a suction effect or physically block the tire from sliding out. Try to dislodge it gently.
Tilt and Turn: Try tilting the tire or turning it slightly to find an angle that allows it to clear the vehicle’s frame or suspension components.

When to Call for Professional Assistance

There are situations when trying to retrieve the spare yourself might be too risky or impossible:

Damaged Mechanism: If the crank mechanism is visibly broken, stripped, or simply won’t engage despite your efforts, it’s time to call for help.
Severe Corrosion: If the entire assembly is heavily corroded and refuses to budge, attempting to force it could cause more damage.
Safety Concerns: If you cannot find a safe, flat spot, if traffic is too dangerous, or if you don’t feel physically capable of performing the task, roadside assistance is your safest bet.
No Tools: If you discover you don’t have the necessary tools for your specific vehicle, or they are broken or missing.
Unknown Tire Condition: If the spare tire itself looks too damaged or deflated to be safe.

Don’t hesitate to call your roadside assistance provider or a local tow service if you encounter these issues. Your safety is always the top priority.

Understanding Different Types of Spare Tires

Not all spare tires are created equal, and understanding the type you have can influence how you proceed after retrieving it. This knowledge further enhances your expertise in how to get a spare tire from under the car and what to do next.

Full-Size Matching Spares

Some larger vehicles, particularly older trucks and SUVs, come with a full-size spare tire that is identical to the other four wheels.
* Advantages: You can drive on it as you would on a regular tire, without significant speed or distance limitations. It can even be rotated into your regular tire rotation schedule after the flat is repaired.
* Disadvantages: They take up more space and add more weight to the vehicle.

Temporary Spares (Donuts)

Most modern cars and many SUVs come equipped with a temporary spare tire, often referred to as a “donut” spare. These are noticeably smaller and narrower than regular tires.
* Characteristics: They are designed for emergency use only.
* Limitations:
* Speed: Typically limited to a maximum speed of 50 mph (80 km/h).
* Distance: Meant for short distances, usually around 50-70 miles (80-110 km), to get you to a repair shop.
* Handling: Can negatively impact vehicle handling, braking, and stability. Avoid sudden maneuvers or heavy braking.
* Tire Pressure: Requires a much higher inflation pressure than regular tires (often 60 psi) due to its smaller volume.
* No TPMS: Many temporary spares do not have a Tire Pressure Monitoring System (TPMS) sensor, so your TPMS light might remain on.

Run-Flat Tires and Tire Repair Kits

Some vehicles, particularly newer models or luxury cars, may not have a spare tire at all. Instead, they might be equipped with:
* Run-Flat Tires: These tires are designed with reinforced sidewalls that allow them to be driven for a limited distance (e.g., 50 miles at 50 mph) even after losing air pressure. This allows you to reach a service station without needing to change a tire roadside.
* Tire Repair Kits: These kits typically include a sealant and a small compressor. They are used to temporarily seal small punctures, allowing you to re-inflate the tire and drive to a repair shop. These are only effective for minor punctures and not for sidewall damage or blowouts.

Understanding the type of spare you have will dictate your next actions after successfully learning how to get a spare tire from under the car. Always prioritize getting your primary flat tire repaired or replaced promptly.

The Importance of Regular Spare Tire Maintenance

Even if you rarely use it, your spare tire needs attention. Regular maintenance ensures that when you do need it, it’s ready to perform its job safely and effectively. This often overlooked aspect is crucial for complete preparedness when considering how to get a spare tire from under the car and its subsequent use.

Routine Pressure Checks

Just like your primary tires, spare tires slowly lose air pressure over time.
* Frequency: Check your spare tire’s pressure at least once every few months, or whenever you check your other tires.
* Correct Pressure: Ensure it’s inflated to the manufacturer’s recommended PSI, which, for temporary spares, is often significantly higher than your regular tires. This information is usually found on the tire’s sidewall or in your owner’s manual. An under-inflated spare is a hazard.

Inspecting for Damage and Wear

Visual Inspection: During your pressure checks, visually inspect the spare tire for any signs of cracking, dry rot (especially on older tires), bulges, punctures, or uneven wear. Even if it’s never been used, rubber degrades over time, particularly when exposed to the elements under a vehicle.
Mechanism Check: Briefly inspect the lowering mechanism itself. Look for excessive rust, bent components, or tangled cables. A quick spray of lubricant on moving parts every year can help prevent seizure.

Practicing the Procedure

The best way to ensure you’re prepared is to practice.
* Familiarity: Once a year, consider taking out your spare tire (in a safe, controlled environment like your driveway) and going through the lowering and retrieval process. This familiarizes you with your vehicle’s specific mechanism and tools.
* Tool Check: It also allows you to ensure all your tools are present, in good working order, and that you know where they are stored.

By incorporating these maintenance tips, you ensure that the effort you put into learning how to get a spare tire from under the car isn’t wasted by an unusable spare when an actual emergency arises.

Safely retrieving a spare tire from under your car is a practical skill that can provide peace of mind during unexpected roadside emergencies. By understanding the tools required, prioritizing safety, and following a methodical step-by-step approach, you can efficiently how to get a spare tire from under the car when needed. Remember that regular inspection and maintenance of your spare tire are just as crucial as knowing how to access it, ensuring you’re always prepared to handle a flat tire situation.
