Well I am not sure they make 17's that fit the LC other than the Rock Warrior wheels. I would just get some 18's with 285/60/18 tires. You probably could fit 285/65/18. You have to make sure your wheels have the correct offset. Somewhere around +25 to +30. That should work. I just order some 18x9 Ultra Gaunltet Wheels wth 295/65/19 Goddyear Duratrac AT's. They are going on a lifted 200.
