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.
