Get a set of Trooper or Rodeo wheels (many different styles to choose from) and take to your local powder coating place. You'll save a bundle and have a guaranteed fit. As for the speedometer issue, just get an inline calibration unit and run whatever rubber your heart desires.

We're about to sell Kathy's '01 Trooper, which has the same exact wheels as on the '99 IronMan but in satin silver. The IronMan's chromes are going on the Trooper and the Trooper's wheels are getting powder coated gloss white, which should look very sharp on the IronMan.
