I had wheels custom made for me by Wheels of Steel in Visalia, CA.

15x7, 4.5" BS, came to about $60 a wheel shipped to Virginia.
These allowed me to fit my 35x12.50 MT/R's pretty damn well (still took some trimming, but not too bad. Here's a pic at full compression in the back.) I have a 2" BL on my X, one inch less than Stormy has.
