Togan, be cautious with changing the size as I did some research on this just last week and you change the rear size and they may not make a bigger size for the front in the same brand. I don't know if that matters to you but I about did the same thing you're thinking of doing and come to find out I could do a 305 in one brand but they didn't manufacture a larger size for the front.

If you increase the tire width, are you going to decrease the sidewall size to compensate for the overall height of the tire to remain close to stock height? If so, the computer wont know the difference. If anything your speedometer might be off by a mph one way or another.

I have an '07 with a wide body kit and I have the 325/30/19 in the rear and the stock 245/40/18's in the front. Been this way for almost its entire life and I have no issues what so ever.
I believe the stagger minimum is something around .5 inches difference front to rear.
