sweet ride. tires are very use and need specific, depending on how you are going to use your rubi and in what terrain will dictate your choice. my best picks for tires are the goodyear dura trac or the Interco Trxus MT. two very versatile tires. they work well every where. the Goodyear will last longer then the Trxus MT but the Trxus will out perform all but the Goodyear MTR. you can drive on the highway in relative quite (which you don't have now) from slick roads, ice, snow, rocks, sand they both work very well.
wheels- you will want to use a 17x8 or 9" wide wheel, with a 4.5" backspace.my best choice is the Interco Birddog. to make this short it's a wheel designed to work and some even say it looks good. if looks are more important then function then any wheel will do. good luck and good wheeling
