Will this rim fit

Hey guys I'm kinda a noob on here. I've seen some of the threads about rim fitment on here and from what I figured these will just fit but I just want another opinion before I buy. I have an 08 Trd sport with a 3" front toytec coil and rear toytec add-a-leaf lift kit on it. And if they will fit how big could I go on the tires? Any help will be much appreciated. Link is below and Thanx in advance.

I did some more research and I hope this helps, right now I have 265/65/17 which is stock rims. These aftermarket rims are 18x9 with -12mm offset. I really like these and would like to put on the biggest tire I could with little to no trimming. I don't mind some trimming but don't wanna go overboard.
