I am about to purchase my first Jeep, so I am ignorant about a lot of the details of this beautiful vehicle. It is a 2005 Wrangler X. It currently has a 2" spring spacer lift on it with very small tires (235's). I was hoping to upgrade to 33" tires. Is that feasible or will I need additional lift? What size can be accomadated with the 2" lift?
