How to Change Tire on BMW I3 (Trusted Guide)

When you drive a BMW i3, you might notice something odd about the wheels. They are much thinner than standard car tires. This unique design helps with range, but it makes finding a spare tire very hard. Most owners do not carry one. You need to know what to do if a flat happens on the road. I will teach you exactly how to handle this tricky situation without needing a tow.

You must check your trunk first. Most i3 models come with a mobility kit instead of a spare tire. This includes a bottle of sealant and a small pump. If you have a flat, stop the car in a safe spot away from traffic. Plug the pump into the power outlet. Connect the sealant hose to the valve. Fill the tire to the right pressure. This gets you to a shop safely.

Why is the BMW I3 Tire Different?

The i3 uses narrow tires to cut down on rolling resistance, which helps the electric motor save energy. This setup is great for city driving, but it limits your options.

Unique Tire Size

The tires are very tall and skinny. You cannot buy these at a normal shop. Most stores have to order them from a warehouse. This means you might wait a few days for a new set. Always keep a spare on hand if you do lots of long distance driving.

Low Rolling Resistance

These tires have special rubber compounds that keep the car moving with less power. This helps you get more miles per charge. If you use standard tires, your range will drop fast. Never swap them for cheap alternatives from a store, as that will hurt your car efficiency.

High Pressure Needs

Because the tires are thin, they need higher air pressure than most cars. Check the sticker inside your door frame for the right numbers. Low pressure ruins the sidewall of these tires. Keep a digital gauge in your glove box. Check them once a month to prevent a blowout.

Rim Width Concerns

The wheels are very light and narrow. Using the wrong size wheel can damage the suspension. You must stick to the official BMW wheel size for this car. If you buy used rims, check them for cracks before you mount any rubber. A bent rim will ruin your ride comfort.

Curb Damage Risk

The skinny tires do not protect the rim as well as thick ones. Be careful when you park near a high curb. It is easy to scrape the metal. This might not cause a flat right away, but it weakens the structure. Avoid hitting curbs at any speed to stay safe.

Rare Tire Tread

The tread patterns are designed for efficiency. They do not handle deep snow or mud very well. If you live in a place with bad weather, you must buy a dedicated winter set. Do not try to drive on summer tires in the snow. You will lose control very easily.

If you have a flat, you should stay calm. The kit will get you to a shop. Just remember that it is only a temporary fix. You will need a new tire soon.

• Park on flat ground.
• Use your hazard lights.
• Check for glass shards.
• Read the sealant label.
• Connect the pump firmly.
• Drive slow after filling.

How to Change Tire on BMW I3

Changing a tire on an i3 is different from a normal car. The car has no jack, and you likely lack a spare wheel entirely. You must follow these steps carefully.

Prepare the Vehicle

Find a flat and level surface to park. Put the car in park and set the electronic parking brake. Turn on your hazards to warn other drivers. This is the first step to staying safe.

You should never try this on a hill or on soft grass. The car is heavy, and it could roll away. Check your surroundings for any traffic before you step outside. Safety is your goal.

Make sure the car is off before you touch the sealant kit. This saves the battery while you work. Take a deep breath if you feel nervous about the flat tire.

Inspect the Damage

Look at the tire tread for nails or sharp objects. Sometimes the leak is just a small hole. If you see a large gash, do not use the sealant. It will not work.

A big tear means the tire is ruined. Call a tow truck if the side of the tire is ripped. You will only waste the sealant if you try to fix a gash. That stuff makes a huge mess inside the wheel.

If the hole is small, you are in luck. Clean the area around the valve stem. This helps the sealant flow better. Check the valve for any debris or dirt.

Apply the Sealant

Shake the sealant bottle well to mix the chemicals. Attach the hose to the tire valve. Make sure it is tight so no air escapes during the process.

Now, attach the other end to the pump. Plug the pump into your car power socket. Turn the pump on and watch the gauge rise. The sealant goes in with the air.

Let it run for about ten minutes. The tire should start to fill up. If the gauge does not move, check the hose connection again. Tighten it if you hear a hiss.

Inflate the Tire

Keep the pump running until you hit the right pressure. The manual inside the glove box will tell you the exact number. Do not overfill the thin tire.

Once you hit the right pressure, turn off the pump. Unplug the hose quickly to keep the air inside. Screw the valve cap back on tight. You are now ready to drive.

Take a moment to clean any mess from the valve. You do not want the sealant to dry on your rim. It can be hard to remove later.

Drive to the Shop

Drive the car slowly for a few miles. This helps the sealant coat the inside of the tire. Listen for any thumping sounds from the wheel area.

Go to the nearest tire shop for a professional check. Tell them you used sealant on the tire. They need to know this before they try to take it off.

Do not drive over fifty miles per hour. Your car is not at full strength. Keep your distance from other cars until you get to the shop for repairs.

Clean the System

After the shop replaces the tire, buy a new sealant refill. You always want a fresh bottle in the car. It is a vital part of your kit.

Check the pump to make sure it is dry. Wipe off any residue from the hose. Store it back in the trunk where it belongs for the next time.

You have done a good job. Fixing a flat on your own feels great. Just keep the kit ready at all times. It is the best way to travel.

If you have a flat, you should stay calm. The kit will get you to a shop. Just remember that it is only a temporary fix. You will need a new tire soon.

• Check tire pressure often.
• Keep the sealant kit.
• Never speed on sealant.
• Visit a tire shop.
• Replace the used bottle.
• Stay off the highway.

Do I Need a Special Jack?

The i3 does not come with a standard jack. Because the car uses a unique carbon fiber body, you must use the official lift points. If you use the wrong spot, you will crack the frame. This is a very expensive mistake to make, so be careful.

Always check the owner manual before you put a jack under the car. You need a specific adapter for the lift points. Do not use a generic floor jack from the store. It will slide off the plastic mount. This could hurt you or damage the battery pack.

If you plan on doing your own repairs, buy the right lift pad for the i3. It fits into the hole on the frame. This keeps the jack steady while you lift. Never get under the car without a proper jack stand.

If you have a flat tire, the best move is to call for help. The car is low and heavy. It is hard to jack up on the side of a busy road. Use the sealant kit instead of trying to lift the car.

• Use official lift pads.
• Avoid the battery area.
• Check the frame guide.
• Buy a specific adapter.
• Never skip jack stands.
• Call for road help.

Can I Use a Normal Spare Tire?

You cannot put a standard spare on an i3. The bolt pattern is not the same as most cars. The size is also too small for the wheel well. You will find that a normal spare does not fit the trunk space. It just rolls around in the back.

Even if you find a rim that fits the bolts, the tire will likely rub against the suspension. The i3 has very tight clearances. Any wrong part will cause a major problem while you drive. Stick with the factory wheels to avoid any trouble on the road.

Some owners buy a skinny spare from a specialty shop online. This takes up a lot of room in the trunk. You lose almost all your storage space for groceries or gear. Most people decide that the sealant kit is enough for their daily needs.

If you go on long trips, you might want a spare in the trunk. Pack it securely with straps. Do not let it slide around during turns. It is a peace of mind item for long drives.

• Check the bolt pattern.
• Measure the trunk space.
• Verify the wheel size.
• Secure the tire tightly.
• Avoid generic spare rims.
• Watch the load weight.

Will a Flat Tire Damage the Rim?

A flat tire causes the metal rim to hit the road directly. This happens fast if you do not stop immediately. The rim will bend or crack. Once the metal is damaged, the tire will not hold air anymore. You will need a brand new wheel.

The i3 rims are light, which makes them easy to dent. You will feel the car vibrate if the rim is bent. If you hit a pothole, stop and look at the wheel. A small dent might look fine, but it leads to a slow leak later.

Never drive on a flat tire to get to a shop. You will save ten dollars on a tow, but you will spend hundreds on a new rim. It is a bad trade. Pull over the second you hear the flapping sound.

If you see a bubble on the sidewall, the internal structure is broken. Replace that tire as soon as you can. Do not wait for it to pop. It is a safety hazard for you and your family.

• Stop the car fast.
• Look for rim cracks.
• Check for bent edges.
• Feel for new vibrations.
• Replace damaged wheels.
• Inspect after big bumps.

Does the Tire Pressure Monitor Work?

The sensor system in the i3 is very sensitive. It uses wheel speed to tell if a tire is low on air. If the pressure drops, the screen will flash a warning. Never ignore this light. It usually means a leak has already started.

When you see the warning, find a gas station to check the air. The system might not tell you which tire is low. You have to check all four with a gauge. It is a simple task that saves your tires from ruin.

Sometimes the light stays on after you fill the tires. You need to reset the system in the menu. Look under the settings tab for the tire menu. Select the reset option and drive the car for a few minutes. It will learn the new pressure levels.

If the light stays on, you might have a bad sensor. This happens if the battery inside the sensor dies. A shop will need to replace it. It is not something you can fix with a basic tool kit.

• Check all four tires.
• Reset the system menu.
• Watch for warning lights.
• Use a manual gauge.
• Replace old sensors.
• Drive to calibrate often.

Final Thoughts

I hope this guide helps you feel better about your BMW i3. It is a great car, but it needs a little extra care. Most of the time, the sealant kit will get you home just fine. Always keep your tires at the right pressure to avoid most issues. If you ever feel stuck, do not be afraid to call for a tow. It is better to be safe than sorry on the road.

Frequently Asked Questions

Is It Safe to Drive on a Patched Tire?

It depends on where the hole is. A hole in the tread can often be patched by a shop. A hole in the sidewall is never safe to fix. You must replace the tire if the side is damaged.

Can I Use Tire Foam From a Store?

You can, but the official BMW kit is best. Some store brands can clog your sensors or damage the inside of the rim. Use the BMW sealant to keep your car electronics working the right way.

Are BMW I3 Tires Expensive?

They are more expensive than regular car tires. This is because they are a specific size for electric efficiency. Expect to pay more for a set of four. You should always shop around for the best price.

Do I Need to Rotate the Tires?

Yes, you should rotate them to keep the wear even. The i3 is rear-wheel drive, so the back tires wear out faster. Rotate them every five thousand miles. This helps you get the most out of every set.

Will Cold Weather Change the Pressure?

Yes, the pressure will drop when the air gets cold. Check your tires more often during the winter months. A few pounds of pressure can change how the car handles. Keep them filled to the factory level.

Should I Buy Used Tires?

I do not recommend used tires for this car. You never know how the previous driver treated them. They might have hidden damage from hitting curbs. Always buy new tires to stay safe on the road.

Will a Flat Tire Kill the Battery?

No, a flat tire will not hurt the car battery. It only affects the wheel and the rim. You can leave the car parked for a few days while you wait for a new tire. Just keep it in a safe spot.

Does the Mobility Kit Have an End Date?

Yes, the sealant inside the bottle has an expiration date. Check the date printed on the bottle once a year. If it is too old, it will not seal the hole. Replace it to keep your car ready.
