Just got a brand new 2011 335 and they came with the following tire package:
3 Series - Approved High-Performance Summer Tire Packages.
M Spider Spoke 193.
18" M Alloy Wheels
Michelin Pilot Sport 2* Run-flat
225/40 18 Y, Front
255/35 18 Y, Rear
I used these tires for about 2 months and had to throw winters on, so they are in very good condition.
Details from BMW below.
Make me an offer!
