Many tire shops will advise you that they won’t fix a puncture if it lies between the side and either the outermost or innermost circumferential channel. To find out their policies, visit the website of the tire manufacturer. Print it out and bring it with you to the tire shop if the news is good. If it can be fixed, you want to use a “plug-patch” rather than merely a plug that is inserted from the outside. For a plug-patch, the tire must be taken off the wheel, put back on, and then balanced.
Find a business with a lever-less tire machine, one that doesn’t contact the exterior of the rim when prying the tires on and off the rims, to avoid getting your rim scuffed.

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 (sidewall damage ruins a tire immediately).
- 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.
Choosing whether to fix or change run-flat tires
What should a fleet manager be aware of when using run-flat tires as opposed to non-run-flat tires? Manufacturers of tire and mounting and balancing equipment agree that run-flats are more challenging to mount and demount due to their special construction.
On the subject of whether run-flat tires can be mended, there is disagreement. The replacement tire limits and suggestions made by the vehicle manufacturer are frequently followed by tire manufacturers.
For instance, Michelin North America Inc. permits the repair of its run-flat tires (Zero Pressure) under specific conditions. 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. Prior to doing so, USTMA does advise vehicle owners to inquire about the tire manufacturer’s repair policy and, if appropriate, suggested repair techniques.
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 may endure many tire changes is the best benefit in terms of cost. It continues to be secured to the wheel inside the tire. It is mental calmness.
Consumers who continue to place a high priority on safety should still assess the advantages and disadvantages of run-flat tires before making their next purchase. Cost is frequently cited as a “negative” of this technology. In fact, run-flat users typically replace their tires 6,000 miles sooner than those who use conventional tires. Additionally, run-flat vehicles have a twofold increased likelihood of needing new tires after a blowout or flat. Run-flat tires cannot be repaired once they have completed their task, therefore this is why.
Other drawbacks include availability, which is frequently difficult to locate and necessitates certain setup criteria, a drop in overall ride quality experienced by some, and a reduction in fuel economy of roughly 1-2 percent.
Despite these drawbacks, many manufacturers and drivers claim that run-flat tires’ advantages in terms of safety and convenience greatly outweigh their costs and replacement problems. The utility of run-flat tires has increased along with technology. The majority of significant manufacturers incorporate run-flat technology into their top-selling tires, reiterating their confidence in this innovation.
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.
Can a run-flat tire be used to repair a flat?
Run flat tires should not have Fix-a-Flat installed. Because the run flat tire structure was intended expressly to show a flat and yet be safe to drive on for a little length of time, run flat tires are not suitable for tire sealant.
How much does it cost to buy a new tire for a BMW?
Common BMW tires range in price from $150 to $350 per tire, however high-performance tires can cost up to and even over $500 per tire. Although you won’t normally require pricey tires, you can call one of our experts with BMW training to learn more about the cost of various tires for your car.
Can run flat Michelin tires be fixed?
According to Michelin, a run-flat may be patched if the sidewall is ripped or punctured but cannot be fixed if the crown area is pierced. If it can be fixed, a tire technician may subsequently use industry-standard radial repair techniques and products.
Can you mend a run-flat tire?
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.
How much do run-flat tires cost to replace?
Run-flat tires are designed to support the vehicle enough to keep it moving at a usable pace so that it may leave the area or get to a repair shop. Obviously, if something sounds too good to be true, it probably is. Well, everything has a cost, and we’ll talk about the advantages and disadvantages below.
There are now three main run fat tire technologies in use:
The most widely used method, often known as zero-pressure tires, essentially involves strengthening the tire’s sidewalls so that they can support the vehicle even when it is deflated.
Pro:
- Better blow-out stability: Steering and handling will deteriorate, but they will still be adequate given the situation.
Cons:
- Run-flat tires need to be replaced 6,000 miles sooner than conventional tires due to rapid tread degradation, according to J.D. Power.
- The stronger sidewall causes a rougher ride.
This kind features a layer of sealant inside the tire that is intended to maintain air pressure when punctured, as opposed to being built to work without air.
strongly resembles and functions like a regular tire.
Con:
- This usually only works if the puncture is less than 5mm in diameter and close to the tread’s center.
This kind can support the weight of the vehicle during deflation by using a support ring attached to the wheel.
- Unmatched capacity to move huge loads at great speeds over vast distances.
- reduced “drivability” and maybe a rough ride as a result of the tire “bottoming out” on the apparatus
Costs are typically between $200 and $500 per tire for a passenger car, which is between 50% and 200% more than regular tires. For the same application, Goodyear sells regular tires for between $110 and $200 MSRP or run-flat tires for between $250 and $350. The device may outlast numerous tire changes because it is attached to the wheel inside the tire, making the auxiliary supported type the most cost-effective option.
Your best course of action will be to research your options and decide what is best for you. Make a choice based on your task, threat, and environment after weighing the benefits and drawbacks.
How long can a run-flat tire be driven on?
A 50-mile drive at a top speed of 50 mph is conceivable in the event of complete pressure loss and limited mobility (no unexpected driving maneuvers). The type of driving, speed, type of road, weather, tire condition, and vehicle load will all have an impact on the run flat distance.
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.
A run-flat tire may have a blowout.
Blowouts are still possible: If a motorist ignores or misses the run-flat warning and exceeds the speed limit or the zero-pressure range, the tire may start to degrade and have the same unsteady effects.
After a puncture, how long do run-flat tires last?
Run-flat tires are intended to work safely and for a short period of time without air pressure. This means that, in the event of a puncture, you can continue traveling for around fifty miles before changing the tire. This distance may be sufficient to get you home or to a mechanic.
How do you determine if a run-flat tire has a hole in it?
How do you determine if the tire has a puncture then? The tire pressure monitoring system in your automobile will still alert you even though it is designed for extended mobility. Additionally, if you look at the tire closely, you should still be able to see that it isn’t fully inflated.
