I have a 2015 with barely 44km on it and tires need to be changed soon. I have the Continental run flats on there now. The car handles nicely and they worked good in the snow but I can't believe how much worn they already are. I am in Canada and they wanted 2k at the dealership to replace the OEM, I told them to shove it. I can find the Procontact RX SSR OEM run flats for about $1000 on tire rack but then shipping and install brings up to over $1400. I can go to Detroit and get tires at Belle or Discount but exchange rate does not give me much benefit. Bridgestone Drive Guard are either $984usd or $1150 cdn and so may as well buy close to home for warranty reasons. Just wondering what choices you make when changing tires and if the run flats are worth it. I have no spare and one time I ran over something that fell off truck in front of that put a hole and the run flat saved me but the rapid wear sucks.
