Tried to figure this out on my own but....

OK, first, HI! Im new to TW and my 06 Tacoma. surprise!! I need help with tires. trying to figure out if ill be able to fit 20x9 with 285 50 20. was planning on leveling so that would lift about 3" i guess, but Im starting to realize that ill never fit those without cutting. that right? that makes me a little nervous, Ive never done something like that before. also the offset for the wheels i want to get is +18 and the backspace is 5.71. Ive read what those things mean but im not sure what effect that will have on my ride quality or the truck itself. last, any links to pics of tacomas with that size W&T combo would be great so i can get an idea of how it looks. thanks alot
