No, all 4 wheels listed on the 1999 page will fit, but they are only 16" rims, except mine which also come in 17". Your stock rims are 18". I have the one's shown below with Pirelli Scorpions (255/60-17"), which is very, very close to your stock size of 245/60-18. Use this link when trying to figure out stock tires compaired to something else.

Also note my winter / off-road setup.
