Finally got my 166 style rims put on!
And here are some pics!
Some photoshop (to spice up blurry image form cheap camera)
Thanks everybody for your tips on rims & tires specs!
So to wrap it up:
2008 BMW 535xi
166 style rims staggered @ 19/8.5F 19/9.5R 40 offset and 72.6 hub centric (both front and back)
Tires: Hankooks 245/35/19F & 275/30/19
TPMS from Tirerack.com
Perfect fit and no issues at all!
Ride Comfort: Huge difference form my stock 17" & 225 tires! The car feels a LOT MORE sportier than ever. There's more road noise but not bad at all with music at low volume. Steering is much more tight and the car seems to inspire more confidence during turns and straight driving!
