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.

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.

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.
