Alternative to the Michelin pss?
I expected incremental improvements from the PSS considering it's such a well-regarded tire, but the difference is definitely worth the step up in category from "Max" to "Extreme" performance. I'm running OEM sizes on the stock 18s and the straight-line grip is now where it should be, even with the Eurocharged tune. It was difficult with the PSS, but I can't really even push the car hard enough on public roads to find the cornering limits. I have some track time scheduled soon to feel them out.
They are somewhat noisier, but I haven't really noticed much of a difference in ride quality. I'm not holding my breath on how much mileage I get out of them. I am aligned to minimum factory spec for rear toe-in (0.28) so that should help, but I'll feel happy if I get over 6,000 out of the rears.
