I have had the Z06 Motorsport 18x10 275/35/18 with 19x11 305/30/19 P Rosso no problems. Why would you want to run a 40 size tire? It is important to maintain the .6 difference in diamter ratio from front to back (back being the taller tire) in order for your stability control to still operate normally.

I run 25.3 diameter tires front and rear and have no issues with the TC or AH. The problems come when the front tire is larger in diameter than the rear tire.
