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.
Thanks. I was thinking 285 rear, is that technically feasible?

We have some shitty / slipery roads here and I have issues in putting down the power properly. I wouldn't worry too much about understeering because as I said road quality is bad and first thing always to happen is rear end brakes loose.

At the track I am quite happy with the stock configuration, so I can switch to that whenever needed.
