Help with 18" pro comp wheels!

I have a 2005 tacoma prerunner dbl cab and am looking to get 7089 procomps. i think i want to go with 18" but i cant find ones without an offset. i was wandering what difference a -6mm offset would make or if they have ones without any. i also cant find any pictures of trucks with these rims in 18" so if anybody has any that would be great. any recommendations for tires that will fit with no lift? Or if 18" rims arent compatible what specifications of a 17" rim would i want? thanks.

 

If you are not going to lift your truck, I would go with 17's. With the 18's, it will look kinda funny in my opinion, because the tires will be really thin (the distance from the top of the rim to the top of the tire). Unless, thats the kinda look you want. More of a 'street' kinda look I guess.

 

im going to put a leveling kit on but i dont think they will be super thin cause its not like their 20" but thats why i want to see some pictures.
