My 330i came with Pirelli PZero PZ4* RFTs. Mine is an MSport with staggered 19" wheels. I've seen quite a few M340i with the same tyres.
The only LCI car I've seen close up had Michelin PS4S. The PZeros are pretty good, but I like the Michelin PS4 I have on my Jaguar better. They're a touch grippier and are also quieter (on the Jaguar at least). I will switch to those (or more likely PS5 as they apparently retain the good stuff from the PS4 but wear better) when I need to replace the PZeros, and will get an inflation kit as I'd rather lose the RFTs and gain a bit more sidewall compliance to alleviate some of the slight jitteriness on less smooth road surfaces.
