We, the i3 owners, face some fascinating issues as a result of the lack of a spare tire on the tiny BMW electric vehicle.

A run-flat insert is what?
In the event of ballistic or terrain-related tyre damage, RunFlat systems, often referred to as RunFlat inserts, are attached into the wheel rims and sustain the tire when it is flat. This allows the vehicle to continue traveling safely for up to 100km.
The internal flexing of a deflated run-flat tire produces a lot of heat, which kills the rubber as well as the underlying steel and fabric structure. To dissipate heat, DriveGuards have something called cooling fins sculpted into the sidewalls. However, after 50 miles, they are pretty well toast.
Let’s debunk the false notion that run-flat tires never require air pressure first. It’s true. Your automobile or truck’s tires cannot carry the weight of the vehicle. The air pressure accomplishes that.
Environmentally suitable tires for the BMW i3
A glimpse of the future is the BMW i3. a concept demonstrating that cars of the future don’t have to be boring boxes on wheels. The i3 pushes innovation with state-of-the-art materials and ground-breaking designs. Bridgestone is the ideal option for a tire on a vehicle this efficient.

Are the i3’s tires flat?
Run with flat tires I’m glad that run-flat tires were not included as standard equipment on an i3 because some current i3 drivers would find this trade-off tolerable, but many wouldn’t. Everything will no longer need to be designed for maximum range as EV range increases.
What BMW models come with run-flat tires?
Run-flat tires, which let you to go up to 50 miles on a flat tire, are almost always included as standard equipment in BMW vehicles. Not having to replace a tire on the side of the road in your smart clothes is one of the main benefits of run-flat tires.
How can I tell if the tires on my BMW are run-flat?
Checking the tire marks on each of your tires is the next simplest method. Run-flat tires will be identified with one of these codes, depending on the brand:
- ROF: Companies including Goodyear, Bridgestone, and Dunlop utilize this marking. Its acronym is Run on Flat.
- EMT: This trademark, which stands for Extended Mobility Technology, is also utilized by Goodyear.
They all essentially mean the same thing: that, if you drive under 50 mph, your punctured tires can still be used for up to 50 miles. This is important because, if the punctured tire warms up (as they tend to do at greater speeds), it could lead to more serious splitting and necessitate the assistance of an emergency repair professional.
Because there is no way to tell if this speed or distance limit has been exceeded, auto repair professionals may refuse to fix run-flat tires as a result of the speed limit on punctured run-flat tires. A run-flat tire that has been repaired after exceeding this limit is likely to still be structurally unsound, which might lead to considerably more dangerous damage down the road.
Is there a spare tire on the 2017 BMW I 3 Series?
Every time we experienced a flat tire, BMW’s excellent tire pressure monitoring system warned us about the pressure drop in the tire before it became so severe that the i3 was rendered immobile. Since the i3 doesn’t come with a spare tire, the TPMS is crucial. There is a little air pump and “Fix a Flat” container in the i3.
Can the tires of a BMW i3 be fixed?
If your tires have less than 2/32nd inch of tread left, it is impossible to fix them, even if the damage is minimal.
It’s time to replace the damaged tire because tires with this tread depth or less are no longer safe.
a hole or puncture outside of the tread region in the sidewall of the tire;
less than 16 inches separates several holes that are too near to one another;
You may want to think about buying a single new tire, two brand-new tires, or a brand-new set of tires, depending on what BMW advises for your particular automobile.
For instance, it is typically advised to replace all four tires at once on AWD vehicles. Why? because for the AWD system to function as intended, having four similar tires is essential.
You might be able to cut costs and buy only one replacement tire if you can replace your damaged tire with one that is the same type, brand, and size as the others.

Does the BMW have a spare tire?
More and more brand-new BMW cars leave the factory with run-flat tires installed. Others prefer conventional tires, despite the fact that many owners appreciate the piece of mind that comes with tires that can extend your driving distance by 50 to 100 miles when flat. So, if a BMW arrived with run-flat tires, can it be used with ordinary tires?
You can use ordinary tires on your run-flat equipped BMW, if you’re searching for a quick and simple solution to that query. Both standard tires and run-flat tires have advantages and disadvantages, and we want to assist you in making the choice that best meets your requirements. One word of caution, though: due to the handling and performance variations between the two tire types, if you’re thinking about switching the run-flat tires on your BMW to standard tires, you must do so on all four of them.
Why should a BMW move from run-flat tires to conventional tires? New BMWs no longer come with spare tires in order to minimize overall weight. Some models come with BMW Mobility Kits in place of spare tires, particularly in performance-oriented M vehicles. The majority of other models have run-flat tires. These tires, also referred to as zero-pressure tires, give you the peace of mind that, even on a long-distance road trip, nothing other than a complete tire failure would keep you from reaching your destination or a repair facility. Run-flat tires have have advantages and disadvantages, though.
What does “run-flat” mean in relation to tires?
Some tires have a prominent “run-flat” label on the side for easy recognition. Seek out markings like a flat tire with an arrow pointing away from it, codes like ZP, RFT or ROF (Run-Flat Tire/Run On Flat), SEAL, or codes like ZP. To see the symbols, if necessary, use a magnifying glass. Check the tire’s rim portion because many run-flat tires come with plastic load-bearing slugs rather than the typical rubber rims attached to the wall.
The following list of brands and their codes:
RFT/ROF/RSC (Run Flat Tires/Run On Flat/Run-Flat System Component) is a trademark of Bridgestone.
- Consult the owner’s manual for your car. The user handbook will explain why your tires are run-flat if they are. A tire pressure monitoring system is included.
- If your car is more recent, it is more likely to have a run-flat tire. Examine the tire on your automobile to find out. BMW is the brand that uses run-flat tires the most frequently on a number of their vehicles. Toyota and Lexus are two businesses that carry out the same activity.
- To see if your car has a spare tire, check. Since run-flat tires do not come with a spare in the trunk, if your vehicle has one, it almost likely does not have run-flat tires. Your car can be run-flat if it has a tire repair kit in place of a spare tire.
- Check the driver’s side dashboard for a tire pressure warning light. In cars with run-flat tires, a Tire Pressure Monitoring System keeps track of the air pressure in the tires.
Ask your car dealer if the vehicle has run-flat tires if you’re still unsure.
Do run-flat tires cost more money?
Run-flat tires are a good idea even if changing a tire is a necessary skill. The additional benefit of removing the weight of a spare tire and tools may further improve fuel economy.
Run-flat tires come in two primary categories: Self-Supporting and Auxiliary Supported. Self-Supporting tires have rubber that is more rigid and durable and can momentarily support the weight of the vehicle while operating at lower tire pressure. If you decide to purchase Self-Supporting tires (see right), you will require a tire pressure monitoring system, which is now required as standard equipment on all new cars by the government. Without one, a motorist could not be aware that a tire has lost pressure. Instead of having firmer and more durable rubber, auxiliary supported tires are coupled to a unique rim that includes a steel support ring that is attached to the wheel and can support the vehicle’s weight.
Run flat tires have been used in production vehicles since 1994; however, for a variety of reasons, they have not yet become a common alternative to conventional tires. “Run flat tires provide convenience to a consumer, but conventional tires are often less expensive and have better ride attributes,” says Sheri Hermann, communication coordinator for Continental Tire.
The cost of anything is yet another common grievance. Run-flat tires cost around a third more than conventional tires on average.
But it isn’t the only issue. Run-flat tires affect your fuel economy even though it might not seem like a benefit to carry along a spare tire. The bigger and heavier tires can cause a 1-2% reduction in fuel efficiency. Additionally, the run flat doesn’t exactly perform as well as its pricing would imply because of the stiffer and heavier construction. They frequently have a rough feel on the road and offer little traction in cold weather.
Last but not least, it’s not always as simple to get your tires fixed if you do get a puncture or lose tire pressure. While some run-flat tires are repairable, they must be taken off the rim for a while and examined to be sure they can be restored. It’s time to buy new tires if they are unable to. On the other hand, the majority of punctures on a standard tire can be repaired using a cheap repair kit.
Run flat tires are still a common feature on new cars despite these difficulties and worries, and the motives are straightforward: security and comfort. Run flats not only allay worries, but they also make a car easier to control in the event of a tire blowout.
Can a run-flat tire be plugged?
A Pirelli Tire LLC official said that a run-flat tire should never be repaired when asked if there are any circumstances in which it can be done.
Run-flat tires are they noisy?
Many repair shops don’t carry these tires because they aren’t designed to suit most automobiles. The run-flat tire’s detrimental impact on a car’s ride and handling characteristics is another significant trade-off. Along with increased road noise, the larger sidewalls also produce a rougher ride overall.
Why do run-flat tires cost so much?
They are typically more expensive, in part because they are “performance” tires made for expensive or fast cars and in part because there is less demand for them. Additionally, since damaged run-flat tires cannot be repaired or reused, you will almost certainly need to replace them. Although it’s probably a myth, I’ve never owned an apartment that I didn’t have to replace.
Rides on run flat tires are also noisier and rougher. Every time you hit a pothole, it can feel like you’ve run over a deer; it can be unpleasant and make you think your car has been damaged, even if you’ve probably not.
