Do you mean the max tire sizes within reason?
You can technically
put tire sizes on the stock 8.5 and 9.5 wide wheels that are totally ridiculous. (tires that look "cartoonish")
If you want larger than the stock tire sizes for your OEM 19's, here are the largest tire sizes that I would recommend:
Front 19x8.5 wheel: 255/35/19
Rear 19x9.5 wheel: 275/35/19
Anything larger than this will overshoot the proper tire dimensions by a significant margin. That will not improve your performance or the handling characteristics of your car. It will also add additional tire weight, and possibly cause undesirable rubbing issues due to the factory wheel offset values.
