Hoping it was just low, and not completely flat, we looked at it closely and could see it was definitely flat.

A system like this is now government-mandated on all modern cars. We first noticed the flat when we re-entered the vehicle because the car told us the front left tire was low via the information screen. We learned quite a bit from the experience and hope you find this information helpful if you’re considering a vehicle with run-flat tires. During a Sunday trip to a park we had a puncture that gave us the chance to see how a run flat preforms while driving deflated, as well as explore the repair/replacement options and see how they might compare to other road hazard management options like a full size spare or temporary spare.

Our impromptu test vehicle was a 2013 BMW X3 xDrive 28i crossover. We recently had an unplanned opportunity to put run flat tires to the test.
