Why Switch from Run-Flat Tires to Regular Tires?

Before we dive into the “how-to,” it’s helpful to understand why many drivers opt to switch from run-flat tires to conventional ones. While run-flats offer a unique advantage in emergency situations, they also come with their own set of considerations:

Ride Comfort: Run-flat tires often have stiffer sidewalls to support the vehicle’s weight without air pressure. This can lead to a firmer, less comfortable ride compared to regular tires, especially on bumpy roads.
Cost: Run-flat tires are generally more expensive to purchase and replace than standard tires.
Availability: While becoming more common, the selection of run-flat tires might be more limited than that of regular tires, especially in certain sizes or performance types.
Repairability: Many run-flat tires are not repairable after a puncture, meaning you have to replace the entire tire even if the damage is minor. Standard tires often can be repaired.
Weight: Run-flat tires can be heavier than their conventional counterparts, which might slightly impact fuel efficiency and handling.
TPMS (Tire Pressure Monitoring System): While not a reason not to switch, it’s important to note that your vehicle likely has a TPMS. When you switch to regular tires, your car will still have this system, and it will function correctly to alert you to low tire pressure.

Understanding these points can help you make an informed decision about whether switching is the right choice for your driving needs and preferences.

Can You Change Run-Flat Tires to Regular Tires? The Answer is YES!

The short answer is yes, you absolutely can change your run-flat tires to regular tires. However, it’s crucial to understand that your vehicle was likely engineered with run-flat tires in mind. This means the suspension and other systems might be calibrated for the stiffer ride and different weight distribution characteristics of run-flats.

When you switch to regular tires, you might notice a difference in how your car handles, especially during aggressive cornering or at high speeds. The ride will likely be more comfortable, which is a major benefit for many drivers.

It’s always a good idea to consult your vehicle’s owner’s manual or a trusted mechanic if you have specific concerns about how this switch might affect your particular car model.

What You’ll Need: Your Essential Tire-Changing Toolkit

Before you start, gather all your tools. Having everything ready will make the process smoother and safer.

Here’s a list of essential items:

Spare Tire: This should be a regular tire of the correct size and type for your vehicle. Ensure it’s properly inflated!
Jack: Your car’s jack is usually found in the trunk or under a seat.
Lug Wrench: This is used to loosen and tighten the lug nuts that hold the wheel on.
Wheel Chocks: These are wedges placed against the wheels to prevent the car from rolling. You can use bricks or sturdy blocks if you don’t have dedicated chocks.
Gloves: To keep your hands clean and provide a better grip.
Owner’s Manual: This is your best friend! It will show you the correct jacking points for your specific vehicle and other important details.
Tire Pressure Gauge: To ensure your spare tire is properly inflated and to check the pressure of your new tires once installed.
Optional but Recommended:
Torque Wrench: For tightening lug nuts to the manufacturer’s specified tightness. This is the most accurate way to ensure your wheel is secured correctly.
Sturdy Piece of Wood: To place under the jack for added stability on soft ground.
Flashlight: If you’re working in low light conditions.
Tire Iron or Breaker Bar: Can provide more leverage than a standard lug wrench.

Step-by-Step Guide: Changing Your Run-Flat Tire to a Regular Tire

Let’s get this done! Follow these steps carefully for a safe and successful tire change.

Step 1: Find a Safe and Level Location

Why it’s important: Safety first! Trying to change a tire on a busy road shoulder or a sloped surface is incredibly dangerous. The car could roll, or the jack could slip, causing serious injury or damage.
How to do it: Pull over as far as possible from traffic. Look for a flat, stable surface. A parking lot or a quiet side street is ideal. Avoid soft ground, as it can cause the jack to sink.

Step 2: Engage the Parking Brake and Use Wheel Chocks

Why it’s important: This is a crucial safety step to prevent the vehicle from moving while it’s lifted.
How to do it:
1. Firmly engage your car’s parking brake.
2. Place wheel chocks behind the wheels that will remain on the ground. If you’re changing a front tire, chock the rear wheels. If you’re changing a rear tire, chock the front wheels. Place them on the opposite side of the car from the flat tire. For extra security, place chocks on both sides of the wheel.

Step 3: Locate the Spare Tire and Tools

Why it’s important: Knowing where everything is beforehand saves time and reduces stress.
How to do it: Refer to your owner’s manual to find the location of your spare tire, jack, and lug wrench. They are often stored in the trunk, under the cargo floor, or sometimes mounted underneath the vehicle.

Step 4: Loosen the Lug Nuts (Before Lifting!)

Why it’s important: Loosening the lug nuts while the tire is still on the ground prevents the wheel from spinning freely once the car is jacked up. It allows you to use your body weight to apply force.
How to do it:
1. Remove the hubcap or wheel cover if necessary. Some may have small clips, while others might need a tool to pry them off.
2. Place the lug wrench onto one of the lug nuts.
3. Turn the lug wrench counter-clockwise. You’ll need to apply firm pressure. If they are very tight, you might need to use your foot on the wrench handle, but be careful not to slip.
4. Loosen each lug nut about a half to a full turn. Do not remove them completely at this stage. Work in a star pattern (loosening one, then the one opposite it, and so on) to ensure even pressure.

Step 5: Position the Jack and Lift the Vehicle

Why it’s important: The jack must be placed on a strong part of the car’s frame to safely lift the weight. Using the wrong spot can damage your vehicle or cause the jack to fail.
How to do it:
1. Consult your owner’s manual to find the correct jacking point nearest the flat tire. These are usually reinforced metal areas on the car’s frame.
2. Position the jack securely under the designated jacking point. If you’re on soft ground, place a sturdy piece of wood under the jack base for stability.
3. Slowly and steadily crank the jack handle to raise the vehicle. Continue lifting until the flat tire is completely off the ground, with enough clearance to remove it and install the inflated spare. Aim for about 2-3 inches of clearance.

Step 6: Remove the Lug Nuts and the Flat Tire

Why it’s important: With the wheel off the ground, you can now fully remove the lug nuts and take off the flat tire.
How to do it:
1. Finish unscrewing the lug nuts you loosened earlier by hand. Keep them together in a safe place, like your pocket or the hubcap, so you don’t lose them.
2. Grip the flat tire firmly with both hands and pull it straight towards you. It might be a bit heavy, so be prepared.
3. Lay the flat tire on its side under the vehicle, near the jack. This acts as an extra safety precaution in case the jack fails.

Step 7: Mount the Spare Tire

Why it’s important: Properly aligning the spare tire ensures it sits flush against the hub.
How to do it:
1. Pick up the spare tire and align the holes in the wheel with the lug bolts on the car’s hub.
2. Carefully slide the spare tire onto the bolts.
3. Once the tire is in place, start threading the lug nuts back onto the bolts by hand. Tighten them as much as you can, again using a star pattern. This helps seat the wheel evenly.

Step 8: Lower the Vehicle and Tighten the Lug Nuts

Why it’s important: Lowering the car allows the tire to make contact with the ground, providing the resistance needed to properly tighten the lug nuts. Over-tightening can strip the threads, while under-tightening can lead to a wheel coming loose.
How to do it:
1. Slowly lower the vehicle by reversing the jack mechanism.
2. Once the tire is firmly on the ground, use the lug wrench to tighten the lug nuts securely. Again, use the star pattern. Tighten them as much as you reasonably can with the lug wrench.

Step 9: Final Tightening with a Torque Wrench (Recommended)

Why it’s important: A torque wrench ensures lug nuts are tightened to the exact specification recommended by your vehicle manufacturer. This is the safest and most reliable way to secure your wheel. Over-tightening can damage the studs or the wheel, while under-tightening can lead to the wheel coming loose.
How to do it:
1. Consult your owner’s manual for the correct lug nut torque specification (usually measured in foot-pounds or Newton-meters).
2. Set your torque wrench to the specified value.
3. Place the socket onto a lug nut and tighten until the wrench clicks or indicates the torque has been reached.
4. Tighten all lug nuts in the star pattern.
5. If you don’t have a torque wrench, tighten them as firmly as you can with the lug wrench, ensuring they are all snug.

Step 10: Stow Everything Away

Why it’s important: A tidy trunk is a safe trunk! Loose items can become projectiles in an accident.
How to do it:
1. Gather all your tools (jack, lug wrench, chocks).
2. Place the flat tire and all tools back in their designated storage spots.
3. If you used your hubcap, reattach it to the spare tire if it fits.
4. Remember to remove the wheel chocks!

Step 11: Check Tire Pressure and Visit a Professional

Why it’s important: Spare tires, especially temporary “donut” spares, often have different pressure requirements and speed/distance limitations. Also, getting your lug nuts professionally checked is a good safety measure.
How to do it:
1. Use your tire pressure gauge to check the pressure of the spare tire. Inflate it to the recommended PSI, which is often higher than regular tires (check the tire sidewall or your owner’s manual).
2. Drive cautiously. Most spare tires are not designed for high speeds or long distances. Check your owner’s manual for specific limitations.
3. As soon as possible, visit a tire shop or mechanic to have your regular tire repaired or replaced and properly installed. They can also re-torque the lug nuts on your spare to ensure it’s securely fastened.

Understanding Your Vehicle’s Needs After the Switch

Switching from run-flat tires to regular tires is a common and often beneficial modification. However, it’s essential to be aware of how this change might affect your vehicle’s performance and how to manage it.

Tire Pressure Monitoring System (TPMS)

Most modern cars are equipped with a Tire Pressure Monitoring System (TPMS). This system uses sensors in each wheel to detect low tire pressure and alert you via a dashboard light.

How it works with regular tires: When you switch to regular tires, the TPMS sensors from your run-flat tires are typically transferred to the new wheels. If the sensors are not compatible or you’re installing new wheels, you may need to purchase new TPMS sensors that are compatible with your vehicle. A tire shop can usually do this during the tire installation.
What to expect: The TPMS will continue to function as normal, alerting you if any of your new regular tires have low pressure. This is a critical safety feature that helps prevent blowouts and ensures optimal tire wear and fuel efficiency.

Vehicle Handling and Suspension

Run-flat tires have significantly stiffer sidewalls compared to regular tires. This stiffness is what allows them to support the vehicle’s weight when deflated.

Impact of the switch:
Ride Comfort: You will likely notice a more comfortable and compliant ride. The car will absorb bumps and road imperfections better.
Handling: In some cases, especially in high-performance vehicles or those specifically tuned for run-flats, you might notice a slight difference in handling. The car may feel less “planted” during hard cornering, or the steering response might feel slightly softer.
Suspension: While your suspension system was designed with run-flats in mind, the change to regular tires is generally well-tolerated. Most vehicles are robust enough to handle this adaptation without issue.

* What to do: Pay attention to how your car feels after the change. If you notice any significant or concerning changes in handling, it’s always best to consult with a qualified mechanic. They can assess if any adjustments are needed or provide insights specific to your vehicle model.
