do you have a link, or pic of the 19.5 wheel idea you mentioned?

wonder what havoc smaller tires would play with gear ratio and such..?

The 19.5's will be the same as any aluminum Alcoa or steel semi wheel you see, You just need to figure out whether yours are hub or stud pilot.

I don't know your tire sizes or rear end ratios, I am assuming your trans has a 1:1 final drive, if you could get me the tire size I could tell you what the increase would be. If you can get me the ratio of your axle I can tell you exactly what your rpm's will be at speed.

for instance though if you from a 275/80R22.5 to a 225/70R19.5 you will see about a 25% increase in RPM's With a 3.55 rear end ratio that works out to about 476 RPM.

If you make it over to Spokane ever Spaldings over there should have good used aluminum wheels that will fit your truck, you just need to get the bolt circle, stud diameter, and find out whether they are hub or stud pilot.
