Thanks for the input Einser. It won't be soon but when my actual set burns out I am decided to do that, I am guessing ridiculous acceleration and cornering speeds reached with even more safety than stock sizes. Only thing which can keep me doing this is when time comes if I move to another country/city with worse road conditions then 30 profile tires on 19s can kill this idea's feasibility and I may be forced to keep continuing with stock sizes or even buy a 18 inch set (which can be the better solution anyway!).
