If your question is how do I disguise my stock truck to look like a hotrod without modifications I found the answer here:
http://www.americanracing.com/browse_ar.aspThese sizes will fit:
15” x 8” with -19 m.m. offset, 3 ¾” backspace, 6 on 5.5 bolt circle
or
15” x 7” with -6 offset, 3 ¾” backspace, 6 on 5.5 bolt circle
Styles available in those sizes are Ventura, Nitro, Baja, Outlaw, Python, Atlas, etc. Most tire dealers carry American Racing and in my case they measured my truck and guaranteed the tires and wheels I chose would not rub. I went with 15 x 8 but to do it over again I would have bought 7” rims for a bit more clearance. Here’s a pic:
