Torque Wench Setting for 17" Alum. Wheel?

[Don SC]

Although this question relates to a previous post about jacking up my 5th wheel, it's a separate topic- I've checked my rv aluminum 17" rims and there's no stamped info on installation torque settings. So I'm back to ask what setting I should put my torque wrench to. I found the following info , but 90-120 ft/lbs is a pretty good spread. Again, thanks.

I just went back to the link and asked the question- he said 110lbs would be perfect for the lugs I have. (1/2 inch) So I guess I've answered my own question... {and you guys thought I was dumb...}

What size lug nuts are they?  

Taken from TireRack.com-

New wheels should be re-torqued after the first 50 to 100 driving miles.

This should be done in case the clamping loads have changed following the initial installation due to the metal compression/elongation or thermal stresses affecting the wheels as they are breaking in, as well as to verify the accuracy of the original installation.

When rechecking torque value, wait for the wheels to cool to ambient temperature (never torque a hot wheel). Loosen and retighten to value, in sequence using the torque procedures listed above.

*If you cannot find the vehicle manufacturer's recommended torque spec, you can use the following as a guide.

Hardware Bolt or Stud Size	Typical Torque Range in Ft/Lbs	Minimum Number of Turns of Hardware Engagement
12 x 1.5 mm	70 - 80	6.5
12 x 1.25 mm	70 - 80	8
14 x 1.5 mm	85 - 90	7.5
14 x 1.25 mm	85 - 90	9
7/16 in.	70 - 80	9
1/2 in.	75 - 85	8
9/16 in.	135 - 145	8

 

 

SERVICE WITH A SMILE

I was editting my post while you were typing Jim. Wow. There's a difference between your numbers and the ones I was just told.

[Alie&Jim's Carrilite]

On our Carrilite with Aluminum rims and 9/16 studs, I run 140..... I also use a 30" torque wrench to achieve this.

My Dexter 7,000 lb axles with 1/2" studs call for 110-120 with aluminum wheels.  I use 120 personally.

I torque my 17.5 rims to 145 ft lbs.

Torque will be based on stud size and threads. Almost all automotive studies are fine thread. The list above will serve you well. My rig has 9/16 studs and I torque to 130 due to having coned lug nuts and aluminum wheels. If your 17.5 wheels are aluminum with coned nuts then you should be in the 130-150 range. If you have 5/8 studs then 140-160.

I originally said 17"wheels and it was a typo that should have been 16". Sorry about the error..I've torqured the wheels to 95 ft lbs. We took our 1st road trip:-( 60 miles) and the lug nuts were still at 95. So it looks like I've muddled my way to success.

9/16" studs are not tight at that torque. Doesn't matter rim size.

What size socket did you use to tighten them?  That may help us determine if you have 1/2 or 9/16 lugs.  For 1/2 lugs, your 95psi is adequate.  If you have 9/16 your loose still.  

[roadrunner7410]

From my 2009 Jayco Owners Manual, 8 lug (9/16 studs) aluminum or steel 16" rims final torque range 120 - 130 ft-lbs.  The acceptable range is 110 - 130 ft-lbs.

They're 6-lug, 1/2-20tpi. I used a 3/4" socket . Thx all! Again- I apologize for my mistake.
