Re-torquing after installing new tires

September 02, 2013, 12:09:29 am

Got new tires installed on the U225.  Being a '94 she has stud piloted (Budd) wheels.  I watched the shop ( a independent Goodyear store who does lots of heavy truck work) un-mount and mount the tires and wheels.  They properly cleaned everything, including the threads with a steel brush before mounting.  They mounted to the proper torque, using a torque wrench and not a air wrench.  They even replaced two of the inner studs.  They recommended in writing on their receipt checking the torque after 50 miles.  Now here in lays the question.  To check the torque on the rear inside wheels, the outside wheels have to be removed.  That would mean checking  the outside rear wheels after another 50 miles???

I'm learning the process of R&R the wheels.
I had new tires installed last year. The installer broke 3 studs on my left rear wheel because the installer didn't know the threads are left on the left side.

I did watch them use a torque wrench when installing.
I took the coach to another shop to have the studs replaced. I didn't watch them do the work, but felt confident that they would do a good job.

I recently removed the left rear wheel myself. The outer wheel was plenty tight, I was surprised to find the inner studs to be snug but certainly not tight. My first thought was that the second shop I went to did not tighten the inner studs. I asked around and was advised that many times when you loosen the outer lugs the inner studs will loose much of there torque. I hope this was the case.

If this theory is correct I would think that when RE-CHECKING torque, the outer lugs are the only thing that need torque to be checked or adjusted.

I'm sure others will join in that have WAY more experience with this than I do. I hope to learn something also from your post.

This should give you all the info you need,


From the Alcoa manual page 29, 30

"Tightening stud located, ball seat cap nuts

After 5-50 miles of operation, torque should be rechecked, unless your documented fleet practices determine
otherwise. Loosen outer cap nuts on every other stud to check the torque on inner cap nuts, then retorque
outer cap nuts. Repeat steps on remaining studs. Check torque frequently from then on. If nuts require
frequent tightening, studs break frequently, or wheel nut seats are pounding out, hardware and mounting
practices should be reviewed. Note: whenever the outer cap nut is loosened ALWAYS retorque the inner cap
nut before retorquing the outer cap nut."
