It has been a very big point of contention within the Q50 community about Infiniti’s choice to opt for run flat tires on the Q50. Not only do run flats ride harsher, cost more but they have a low thread wear rating of 280AA which translates to 18,000 miles only. Lastly run flats are great if you “plan" on having protection against getting a nail/screw etc, but if it ends up being a side wall damage or damage due to a big pothole or other object then the run-flat tire is pretty much useless. Call me old school, but one one the first things my dad taught me was to change a spare on a car before I could even drive the car - secure car with chucks, loosen lug nuts, jack up, remove flat, replace with spare, soft tighten lugs, lower jack, fully tighten lug nuts, off you go.
