I don't see too much about the factory 18's I took a chance and installed the wildpeak At3 265/65/18. Lift setup is the eibach pro at 2.7in, 1.5in wheel spacers and 2in proryde blocks in the back. There is a fairly decent amount of rubbing with these tires. Trim the waffle and cut the corner of the pinch weld. In case anyone else was wondering. Not many people have the 18s from all the reading I have done.
