What is the widest tire you can put on the OEM 19" wheel without any modification? I thought I read somewhere that D3 was doing 285s...

I had 285/30/19 no problem.

Thats actually 2" smaller... 275/40/19 is 27.7" tall. 285/30/19 is 25.7" tall....

Sorry I meant 35 not 30. I had 285/35/19. The 285 is the width not the height.

I am sure you can go wider then that. 285 looked pretty good from the back.

BF Goodrich GForce KDW2

That's what I'm running, and they are great! I wish I wouldve gone with a 305

305 on a 9.5 wheel??
I thought stretching tires was the thing to do now?

Did you get traction active coming on with the rear tires? I just put that size on the rear and its making it pop on and the abs kicking on.

Wider is not always better. When you shoehorn a tire that is to wide for the rim, the rotation of the side walls will cup the tread resulting in loss of contact patch at the edges. This results in lost traction, accelerated wear in the middle of the tread and slightly less performance due to the increased rotational mass of the heavier tire. I would recommend picking tires that fit the stock rim size.
