But according to the owner’s manual, changing a BMW’s original equipment run-flat tires is not an option. The U.S. Tire Manufacturers Association (USTMA) recommends the same run-flat tire repair techniques for both run-flat and non-run-flat tires.

So, are they patchable?
Patching is still an option in some circumstances. It all relies on the type of damage or puncture the run-flat tire has sustained.
Run-flat tires enable you to continue driving even if all or portion of your tires lose air pressure. This is made feasible by the design of the tires.
They have sidewalls that are strengthened, which allows the tread to keep surface contact with the road.
Remember that the contact patch or tread is what allows tyres to give stability and grip.

You can patch it as long as the nail is in the tread; just make sure a top-notch shop handles it. Over the course of a particularly frustrating four months, I had three nails in the same tire. I had no intention of buying new tires three times. The only drawback to repairing them is that if you frequently drive at speeds of 100 mph or more and cause the tires to become extremely hot, the patch may come off. Unfortunately, the majority of Americans don’t have to worry about this.
Can run-flat tires be repaired? Or should you swap them out?
Knowing what kind of tires your automobile has can help you decide what you can and cannot do safely if you ever find yourself in a challenging scenario. The majority of BMW vehicles come with run-flat tires. They do this because it offers their clients a few more advantages:
- The main advantage of a run-flat tire is that it enables you to continue driving for up to 50 miles at a speed of 50 miles per hour. This eliminates the need for a person to get out of their automobile on the side of a busy road or attempt a tire replacement in the dark.
- More stable after a blowout: Because a run-flat tire can maintain the weight of the car without any air, after a sudden deflation, steering and handling will resemble normal.
- Reduced vehicle weight: The weight of the vehicle is decreased by the removal of the maintenance tools and the spare tire.
How do you tell whether your tires are BMW run flats or not? On the sidewall is all the information you require. The RSC label is what you want to look for on BMW automobiles.
When run flat tires have been driven with a severe underinflated or zero pressure state, most manufacturers advise replacing them. This is due to the inability to confirm the integrity of their internal structure.
Now, if you have regular tires and one of them sustains damage, the other tire might be fixed if it satisfies the requirements listed below:
- The flat tire has not been driven on.
- Your tire’s tread area is the only area that has been damaged.
- The hole is barely bigger than 1/4.”
The right approach to fix a flat tire is to fill the puncture hole from the inside and then cover the repair with a patch. Your tire should not be plugged. Ever. The tire does not need to be removed from the wheel for plug repairs to be performed properly. It is faulty since a plug is just slid into the hole. Ask your tire center to demount the tire so you may inspect the inside and outside in its entirety. Tire repairs are to be made only after a careful examination.
You will need to replace the damaged tire if the three aforementioned requirements are not met. Don’t forget to check the tire on the opposite side of the automobile; if it has a shallow tread, you should at the very least replace it.
Michelin advises changing all four tires at once, but if only two need to be replaced, make sure the new tires are the same size and type as the old ones, and request that the dealer always mount the new tires on the vehicle’s rear axle when it is practical. Please merely replace the tire if there is ever any doubt about its integrity. The security of you and your passengers is not worth any amount of money.
Run-flat tires—can they be repaired?
Goodyear Run On Flat Tyres can be fixed by a certified tyre technician after a thorough inspection and study of the tyre history, even though not all manufacturer run flat tyres can be repaired. It is advised against fixing the tire if there is any doubt. Only one repair may be made to a tire during its lifespan; the tyre specialist is responsible for all repairs.
Under the following circumstances, Goodyear does not support tire repairs:
If a sharp object damages the sidewall section of the tire, either inside or outside, it could significantly shorten the tire’s travel time and lifespan.
tires that have traveled a significant distance with low or no air pressure
Are all BMW tires run-flat?
BMW made the decision in 2009 to make run-flat tires standard equipment on all of its vehicles. The brand’s partnership with Bridgestone gave customers better fuel efficiency and a safer way to repair a punctured tire. The benefits and drawbacks of owning a BMW are highlighted to assist owners in making that decision.
What is the price of replacing the run-flat tires on a BMW?
What is their price? For a passenger vehicle, Run Flat Tires typically cost $200 to $500 per tire, which is 50 to 200 percent more than regular tires. The fact that these tires can endure many tire changes provides the best financial benefit.
After a puncture, how long do BMW run-flat tires last?
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.
What kind of tires does BMW suggest?

When shouldn’t a tire be patched?
Never patch tires with punctures in the tread larger than 1/4 inch. Repairing tires that have treadwear signs on them or only 2/32 inch of tread depth left in any part of the tread is not recommended.
Why are run-flat tires so difficult to fix?
Run-flat tires that have been driven in a state of extreme underinflation or zero pressure will not be repaired by Tire Rack since it is impossible to determine the service conditions they underwent and the integrity of their internal structure.
Is it acceptable to switch out run-flat tires for ordinary tires?
I can use standard tires in place of run flats, thus the answer to both queries is yes. As long as it complies with the manufacturer’s specifications, ordinary tires can totally replace flat running tires. A premium tire not only raises the standard of your car but also guarantees your safety.
One thing to bear in mind while getting ready to replace your run-flat tires is that each type of tire has a unique design and application. To ensure that every tire performs to its utmost potential, manufacturers carefully calculate every step of the production process.
When switching from run flat tires to ordinary tires, there are a few considerations to make.
Flat tires have the unique ability to keep you moving safely for a limited distance and time even after a puncture. Even under challenging circumstances, the weight of the vehicle may be supported more effectively because to the unique design’s thick walls composed of high-quality heat-resistant rubber.
When changing run flat tires for ordinary tires, it would be wise to have the appropriate backup equipment for emergency movement. Regular tire vehicles might not come equipped with a spare jack, rim, wheel, or tire because run flat tires are the emergency answer. Pay attention to these factors for your protection.
Specifications may change when moving from run flats to standard tires. You should select standard tires that adhere to standards for various factors, such as size, thickness, vehicle weight capability, etc., in accordance with the manufacturer’s recommendations to ensure consistency and prevent dangerous risks in the future.
What occurs if a run-flat tire fails?
The bad news is that new technology is reshaping the evolution of Homo sapiens to the point that, in a generation, very few of us will be able to accomplish a simple task that man has been performing for millions of years—that is, change a tire. Nevertheless, technology demonstrates our species’ progress. Nowadays, a canister of tire sealant or a telephone to call for roadside assistance are more likely to be included in a vehicle’s standard equipment than a spare tire. Except if you have run-flat tires, of course.
A cross section of a run-flat tire from Bridgestone demonstrates how steel and rubber work together to keep you moving. 50 miles at least. (A) Molded fins on the tire’s outside edge absorb heat to prolong tire life. (B) The sidewalls of the deflated tire are reinforced to prevent collapse.
To get you to a repair shop, a run-flat tire will, uh, run flat for 50 miles at 50 mph. It is designed with rigid sides so that it can sustain the automobile even when deflated. Despite the fact that the technology has been present since the 1980s, the Bridgestone Drive Guard is the first to truly enter the public, and it does so for a cost that is on pace with a touring tire of a similar quality ($100 to $200).
Perhaps. Only vehicles equipped with a tire-pressure monitoring system (TPMS) that notifies the driver of a pressure drop should have run-flat tires installed. The technology can be retrofitted on older automobiles, and it has been available on the majority of new passenger cars from 2008.
Run-flat tires from earlier generations were too heavy, too noisy, and not long-lasting. The RideGuard, however, has a taller profile and provides a better ride. With a deflated front-left tire, we manoeuvred a Toyota Camry outfitted with them through a challenging course. A flat normal tire would have come off the rim in one tight turn, yet the DriveGuard remained in place. Well, sort of: A mark left by a bridge stone revealed that the tire had moved a little bit around the wheel rim, which engineers deemed acceptable. Under braking, it tugged somewhat and made audible noise, but not the flapflapflap of an usual flat. On a slick course, we discovered that the grip on DriveGuard and the classic Turanza from Bridgestone was identical.
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.
Unless it’s simply a small puncture in the tread and you spotted it quickly, probably not. You’ll typically require a new tire.
Well, a bent rim cannot be fixed by sealant and compressor kits or run-flat tires. Run-flats also generally have a lower profile, which means that they offer even less rim protection. If a rim breaks, you won’t have a fifth wheel, so if a spare is an option when purchasing a new vehicle, get it. Show a teen how to change a tire if you encounter one. in the interest of the species.
When should run-flat tires be changed?
Let’s say you have one damaged run-flat tire. Is it possible to fix the tire? It depends, is the answer.
In their FAQs, Bridgestone states that “A run-flat tire might be rendered useless due to a puncture or other road danger.” It relies on “vehicle speed, load, and maneuvering; the degree of inflation pressure loss; and ambient temperature,” in addition to the “extent and position of a puncturing object,” although “certain punctures may be mended under specific conditions.”
Run flat tires cannot be repaired if the tire has a “Do Not Repair” label on the sidewall, the tire was driven with an inflation pressure below 15 psi, the tire has abrasion damage on the outside or inside, or if the tire has any other unrepairable condition.
It’s best to have a skilled technician handle the work if you want to make sure your tire is fixed or replaced correctly. Your tire will be thoroughly inspected both inside and out by the tire professionals at your neighborhood Firestone Complete Auto Care to see if it can be fixed. Check your owner’s manual as well. Some automakers advise against using repaired tires. The tire’s warranty, if any, can be voided if an RFT is repaired.
