I agree with Mr. john. Just lifted my TJ and I went pretty extreme. With what your thinking of, I think the tires will look and do fine for what your doing. In fact they will fill the wheel wells and look great. My other Jeep is a 01' Lerato and I bought it with a larger tire than usual to boot. No speed-o change was necessary. If you want to get some well clearance, throw a 1 or 2' lift on it, body lift. But I wouldn't go to far. Have fun and get to know what it can do before going beyond what you need. The trasition can be extensive keep that in mind.
