I'm currently running 265/65/R18s on my '02 RR. Has anyone tried 275/70/R18s? I need to go up a size to keep up with my Landcruiser friends. I'm planning on lifting the EAS an inch, the bump stops and inch, and adding some modest wheel spacers and fender flares. Should I figure on regearing when I make this change? Please let me know your thoguhts.
