I'm looking at changing out the 18s on my truck. Stock set up is 265/65/18 on a 18*8.5 with 4.75" backspace and a 24mm offset. New wheel I'm looking at is a 18*9 with a 5" backspace and a 0mm offset. Plan is to keep tires and wear em out at which point I'll go 275/65/18 to fill the wells a touch more. Problem is I can't get a straight answer as to where these will sit. Online calculator says .94" one tire shop says 1/4" another says 1 1/4". At most I wanna be flush with the fender. Anyone who can chime in I would appreciate it. Thank you.
