19" wheel & tire fitment question on 07 c219 255/35/19

Is their any issue upgrading the oem staggered 18" wheel setup to 19x8.5" wheels, 32° offset (f&b) using tires sizes 255/35/19 (Front) & 285/30/19 (back)?
Reason I ask, Tire Rack has recommend a 245/35/19 front and 275/30/19 in the back. Will the increased 4° offset vs oem effect my ability to run 255/35 in the front?
The car has been lowered 2" using links on airmatic suspension but I can always adjust it if needed since I'm experiencing some camber wear on the old 255/40/18. Camber adjustment kit is in route.
Is there a recommended/optimum 19" tire setup for street and occasional track use?
