Hutchison makes the wheels that AMG puts on the H1's (one piece steel, 2 piece steel, and several varieties of 1 and 2 piece aluminum). Heavy off-road use mandates a 2-piece wheel because it gives you a dual beadlock & a runflat. The one piece wheels give you a beadlock on an inner bead only or a runflat.
GT, inc. (Cepek) also makes aftermarket wheels for H1's. As long as you use a Hutchison (stock) or Cepek wheel, it will have the correct offset and be set-up for CTIS.
