I wanna know if I can go 19x11 all around and if I can wat offset for the front and back with wat size tires

 

Welcome to the site, the widest square setups that I'm aware of are 10.5 +35s, check the first couple pages of this thread for some pics & info. Also there may be clearance issues with the upper section of the steering knuckle with wheels that wide that will have an offset positive enough to stay inside the fenders. I doubt you'll get that setup to work, at least without having to pull the fenders.

Someone running 20x11 all around +25 f +15 r tire sizes might change since you wanna run 19s though. Maybe search their posts to see more pics/info.

 

Yikes! I remember that setup, not what I'd want for a daily, but to each his own right
