Stock tires are fine but not the best preformance wise. Have tow straps and have someone go along with you. Access obsticals before going over them and see if you can make it so you don't tare anything up. A stock jeep can go a long way.
YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.
