I have a 335si 2011. Would like to get new tires. Not run flat! it is a convertible. Any recommendations?
You do not have a spare tire in this vehicle so if you do go away from runflats just keep that in mind.
Search tirerack.com and see what you can narrow down to, given whatever performance priorities you might have.
I believe continental tire makes a roadside tire repair kit that comes with pump, sealant, etc. so you don't have to worry about a spare. I plan on not going with run flats myself.
I'd look into either the Michelin Pilot Super Sports or Michelin Pilot Sport A/S 3. If you're looking for something a bit more budget friendly the Continental ExtremeContact DW or DWS are good choices as well. As bobgto said Continental makes a roadside tire kit called the ContiComfortKit, or you can go OEM with the BMW Mobility Kit. These will help if you get a flat via a nail puncture or similar and I would definitely keep one of these kits around as there is no spare at all.
I drove the PS A/S 3. They were in a word, AWESOME. I'm a Toyo guy and don't have much experience with any other tires.
