I have 18x8.5's with a 0 offset inside 285/60/18's (31.5"). I also have a 2" lift. I was planning to step up to the same tires you mentioned as well. To do that I will need to lift another 1" or do a lot more hacking - or possibly both. Keep in mind, the width of the those wheels. My 8.5's stick out already (even with the lift) and yours would stick out another 1/2" past mine if you go with the 0 offset. Not that you have seen my VX... but you might want consider a thinner rim. If -19mm offset moves the wheel inward you might be inline with my 8.5's or even better, but if it moves the the rim outward you don't want it, IMO.
