Michelin pilot super sport catergorically can be used as a daily drive. Have them on my 335d (57k) and only on second set since buying new with car. Also had them on my old 335d and notched up nearly 30k on rear and 38k on fronts. And just for balance also have them on my z which does hardly any miles.
Highly recommend MPSS tyres for performance and wear, quite loud tho but not a prob in the zed!
