The stock Pzeros are coming to an end, they've got somewhere around 27-29K on them and maybe a few months to go. For general driving they're ok, but hard cornering is a bit interesting at times. I'm thinking about the Goodyear F1s. This car is a daily driver so gotta stick with something all season. What have you s197 guys gone with?

BTW, looking for 235/55ZR17.
