the only falkens worth running are the rt615's. the only hankooks worth running would be the rs3 ( but i think? those are only in 19(?).

hearing of NEW recall? issues with the NEWEST goodrich g-force ( rats and w t f!?! ) leaving michis ps2's ( best ) p zeros clearly ( to me.. next best ) cheaper than michis by far and N rated and proven.. and REALLY inexpensive vis a vis $ vs performance.. and of course, the sumi's you're considering. i just don't "think" the sumis are a trade ( UP?! ) and the differential in cost ( sumi's VS vs the pirelli p zero ) makes that a zero sum choice, in my book.

p zeros = rears 375 max. fronts 195 max. tires are ( again, in my book ) the worst place to try and save a buck on this car.

 

IMHO, the HTR ZIII is a good choice for anything short of track driving. I've had them on a few of my previous cars - supercharged S2000, E55 AMG, C63 AMG. They don't have the ultimate grip or responsiveness of a Michelin Pilot Super Sport or Yokohama AD08R, but they are way cheaper.
