The crown in the road should never do that if you have good/proper alignment.

Well I am going to have to disagree on that. Drive on a well crowned road and then let go of steering wheel. You will drift to the right. Good alignment or not.

I suppose we will have to gracefully disagree on it then ...

maybe that is your experience with it, but I can assure you that if you set up your rear tandems for correcting crown in the road, then no extra wear (due to crown in road) will happen to that outer passenger steer tire. - I have more than 1.3 million miles on my truck,.. I do all my own axle alignments including having had them completely out of the truck and back in a few times, and have never experienced that kind of wear. There is no absolute reason that a truck cannot be set so that the crown in the road is compensated via the drive axles (+ proper caster) vs letting the steer tires eat rubber off them all the time. -- take those blinders off and FIRE THE MECHANIC WHO IS DOING S#$IT ALIGNMENTS ON YOUR TRUCK!!!!

-- My truck does not "drift to the right" either. -- it never has,.. not even when it was brand spanking new, not even the first day I drove it for the first time, and it still does not to this day. - I have to say though, that the mega-fleet i purchased it from,.. the first day it arrived on their lot, they adjusted the axles for the entire truck before it was given to me (brand new truck with only 13 miles on it). -- Hence, why I stood there, watching them,,.. and asked "why did you offset the rear axles like that?" ... and the reply was "because of more than 2,000 trucks in the fleet, offsetting them a bit prevents eating steer tires vs. when they are perfectly straight. Adjusting it a bit saves us a bunch of money on tires every year". ... They then went on to tweak and adjust on several other things as well that they knew they had repeating problems with. Things like re-torquing air-bag retaining bolts that tend to come loose on new truck, re-torquing the u-bolts to maximum allowed torque, grinding out the alignment stud holes for the front air bags to prevent pre-mature failure when they move around/settle., replacing the levelling valves with an updated valve body, re-torquing the tranny mounting bolts, a bunch of other things.

Guy stood there and (roughly) said to me that these newer trucks are like buying a cbhineesuim machine tool. - You gotta take it apart and finish/fix all the crap the maker was in too much of a hurry to do properly on a friday afternoon. When you buy and send 500 at a time into service, you tend to see that repeating pattern of mistakes pretty fast.
