Will 19x9.5 40 fit.... I was ordering 19x8.5 45 now im not sure... So.whats.the best choice? I have TRD lowering springs At the moment

That will fit with minimal issues. There are folks going 9.5 wide with +35 (or less) offset and they are doing fine.

should fit without a prob. 1stOne is on 18x9.5 +40 with 255/35/18 so you'll probably be fine with 255/35/19 or 255/30/19. Or if you wnna stretch, then it'll make it even easier. I believe you might get slight rub at full turn though.

My tires are falken 245/35 19 jumped on them last week couldnt resist the deal. I have my buddy working at finding some 9.5 with a 35 offset which i think should work. If im not happy hes going to get my fenders rolled. Ill post what he comes up with for fitment and style.
