Flat tires are unquestionably the biggest burden, especially because they tend to happen unexpectedly. You’re stuck with the options of waiting endlessly for roadside assistance or doing the dirty work yourself and changing the spare if you’re lucky to have one hanging around in your trunk.

There is a possible solution, we introduce to you the run-flat tire. Also known as 0-pressure tires, have the magic of supporting the strenuous weight of your vehicle within a 100 mile radius of your stopped destination of which is hopefully the repair shop! As awesome as it sounds, there is still a dilemma about these “perfect” solution tires.

According to Edmunds, these run-flat tires are standard on 14% of vehicles. These numbers recently doubled in the past decade but have unfortunately hit a hard steady stop with consistent numbers of 13-14%. They’re most common in the following brands: BMW, Mercedes-Benz, Mini Cooper, and Cadillac.

The Run-Flat Tire Pros

  • The Ability To Drive On A Flat Tire: The overall benefit that comes with the run-flat tire is the ability to continue driving up to a 100 miles after all the air has left the tire. This means you get to keep your clothes clean and stay inside your vehicle without worrying about waiting a decade for roadside assistance. After your tire has run out of air, it is important that you reduce your driving speed to no more than 50 mph for your safety. The owner’s manual will have precise figures for each tire/vehicle application.
  • Improved Stability After A Blowout: Given that this tire technology has the ability to support the the car after a tire has no air, a sudden blowout or deflation will result in a decreased weight transfer and tread destabilization. Steering and handling will continue to be fairly normal.
  • Decreased Vehicle Weight: Theoretically speaking, the weight of your vehicle will go down thanks to not having to have the spare wheel and tire repair tools.
 

The Run-Flat Tire Cons

  • No Spare Tire
  • Blowouts Are Still Possible: The driver needs to be attentive at all times. It is imperative that you do not drive past the 100 mile range or over the recommended 50mph speed.
  • Difficult To Be Aware Of Low Air Pressure: The sidewalls lose the ability to bulge when the air pressure is low given to a harsher construction when run-flat tires are used. A low tire  pressure system is recommended in order to be alert of your tire pressure to prevent a flat.
