New tacoma owner need help

Hello everyone I recently purchased my first tacoma in December to drive in nj horrible winter and to use for work in the summers and an overall daily driver.
I am one of those guys who buys a car and can't just leave it alone I have to tweak to make it my own. I have some car "modding" background but from a whole other ball game in the VW world. But reading through a lot of post I see a lot of familiar terms being tossed around.
But to the point. I just bought a ome 3 inch lift kit and having a very hard time finding the right size tire to go with. I want the biggest I can get. The car came on some pretty nice looking TRD off road wheels which I plan on keeping if I can
Now I've have been searching a couple days now and can not find any where the back spacing specs for this wheel is. I really would like a 285/75/16 but don't want to run into horrible rubbing and have to waste my money minor trimming of plastics I okay with. Anyone out there know anything about this wheel and what tire I can run. And do a lot of people run this wheel?

 

The wheels look like the TRD ones in Toyotas catalog, I also think they are on The Toyota of Dallas site so you might be able to find the specs there. I believe when they first came out they were called the Ivan Stewart Baja Edition wheels if I'm not mistaken. Very nice looking wheels and they are still available just google TRD Wheels. Below is the link to the wheels.
