I actually heard someone here mention H2 wheels failing somehow off road - but I hesitate to say anything about it myself as that is nowhere near documented proof. If those tires are what you are trying to fit, you may be able to go with 17x8. 5, which opens up a few options (I happen to be looking into rims myself for 35x12. 50s . . . ). Checking both Discount Tire and Tirerack showed a couple leads. And just to be clear, clearing the caliper is a separate issue than back spacing. Our calipers are just big, and the factory 17s have more clearance than many aftermarket 17s. Proper back spacing will keep them from sticking out too far. Those APP (now Shindle Engineering?) wheels are spendy - if you are in that range you might try some custom billet wheels from Boyd Coddington or the like.
American Racing is making a rim that I like in three different color options called Cannon (Dale Jr. series) or Thug (ATX series - Teflon coated) that Tirerack says fits our trucks. AR site says it is 17x8. 5 with 5 3/8 BS (15mm offset).
Discount Tire shows a few wheels, but one in particular is an 8-hole in a flat plate model (MB Wheels "72")that is 17x8. 5 with 25mm offset (which I figure is about 5 3/4 BS).
If you dig up any more specific information on these wheels or others, please let us know. Especially if you actually buy some and fit them up!
