I plan to change mine to 235/85R16...It will correct my speedo error to match GPS, lower my highway cruising revs ~150 RPM and they are 10mm narrower than stock so less aero drag.

Again, it depends on what truck he has...
There are four different tire sizes used on 2002 Silverado 1500s:
235/75-16 (2wd)
255/70-16 (2wd)
245/75-16 (4wd)
265/75-16 (4wd)
So, if he has a 2wd, switching to a set of tires off a 4wd will result in an overall higher ratio over stock (either a small bump, or a significant one).
The set of wheels I got were from an '05 Tahoe 4wd with 265/70-17 tires which were about 2" taller than what I had stock. Silverados, Tahoes, Suburbans, and their GMC twins can all swap wheels ('99+, '88-'98 too, but occasionally may run into clearance issues with the smaller wheels) so there are a lot out there to choose from.
