22,5" rim torque specs

Getting ready to have my tires changed. Freightliner told me the lug nut torque specs are 450 ftlbs. This seems high to me but that is what I'll go by. Just curious, what you guys know about this. Thanks!
The rims are the polished aluminum Alcoa rims.
  • Not sure about aluminium rims or your wheels but my older unit with steel wheels calls for 450ft. lbs of torque on the nuts.
  • I believe the only difference in torque values for the aluminum wheels vrs the steel rims is that you must re-torque them after 50 miles of travel to allow for the aluminum to adjust. 450 ft pounds sounds about right.
  • I believe 450 is correct. Thats what ours were torqued to when the new tires were installed.

    Lug Torque is a function of the Lug and the NUT and is often printed on the attached washer (The washer that is attached to the nut) mine is in fact 450 Pounds.. The Rim is not the determining factor. the Bolt and Nut are

    Over torquing can strip the nut/bolt.. Undertorque and .. By By Nuts. and wheel and OUCH.

    SOME RIM Types.. Need to be Re-Torqued a short distance down the road. (Dealer **SHOULD** Tell you if yours are like that.. Did not my daughter on her car. which is why I know this)
  • 450 is correct but a lot of big tire shops just run them on with a large impact and send them out the door.

    Well,
    That's up to the owners of those trucks to allow that practice. Yes, as has been stated, 450 ft.lbs. is quite common on the larger wheels, no matter if they're alloys or not. Ours on our coach, an '04 Itasca Horizon 36GD with the CAT C-7 330HP, are 450 ft.lbs. I purchased a 100-600 ft.lb. click type torque wrench, made by K&D a few years ago off Ebay for $75.00 and it works flawlessly.

    I use a Torque multiplier for breaking them loose but, then use my hex drive impact for final removal of those 33MM lug nuts. I do what's needed while the wheels are off and, re-install them and use that torque wrench for cinching things down the right way.

    And no, in decades and decades, I've never, ever re-torqued any wheels, any engine heads, NOTHING after any amount of miles. Nothing has fallen off yet.
