Glad you figured it out, but I'm curious: does your 2000 sticker actually have a 30 size on it? Maybe you have a special edition or Rubicon? If not, it should be P215/75R15 (Sport), P205/75R15 (SE), or P225/70R16 (Sahara).
His profile says 2000 Sahara which I thought was before they offered any 16" wheel options, but between Sahara and his door sticker I would guess his originally came with the 30" tire package and had it's 15" wheels replaced with 16".
