tire prefs
i've had pirellis on my last M3 and they were good... but that's about it... just good.
personally, a little overpriced.. noisier and wore really fast. i switched back to michelin pilot sports...
on my current M3, i have continental contisport for my winter rims the standard OEM flat silver...
my spring/summer config will be back to the chromes with new set of mich pilot sports... i personally love them.. had them on my older 325 and 328 and i've been happy with them the whole time... great stick, good even wear.. durable enough (mileage wise) and not too unreasonable price wise.
