I have a 2003 Wrangler Sahara and need new tires bad. What is the most I can do to make it look "cooler" without getting a lift? I know the biggest I can get is 31x10.5... Would spacers allow me to get bigger tires? I'm planning on getting new 15" wheels too. Probably procomp. I'm just a jeep novice and want to get the best look with the little money I have.
