The overall tire height isn't a dead even exact match, but it's as close as you're currently going to get given the current tire size options available from the PS4 model line today...  |

Overall happy with Michelin Pilot Sport 4S tires.

These look great, guys. I would love to do this. Any concern about warranty and running larger tire size than stock (also being not BMW-starred tires)? This is my first BMW and it already needed a bit of warranty work so not sure how strict they are with things like this.
Also, does going wider tires hurt MPG much or negligible? Not that it matters with our cars, just generally wondering.
