Curious as to what aluminum lugnuts should be torqued to. Factory numbers?

 

Yes...

The issue with them that I've experienced is that once you take them off and reuse them a couple of times, they work their way loose.

Also, if you over torque them, they will back out.

I'm talking about the Rays lugs that I used.

 

I tq mine at 90 and have never had a issue. Never came lose either and they have been on and off many times.

 

Max. torque for my Ray's lugnuts is about 87lb/ft.

I use 85lb/ft since aluminum will compress a little bit.

However, I figure that after the first few uninstall/reinstall cycles, it will have compressed enough to negate that. I also figure that the thermal expansion rates of aluminum and duralumin (aluminum) are about the same. So they would have LESS of a tendency to loosen up under high heat conditions after they have been fully compressed.

Since they are forged and hard anodized, the compression should be VERY minimal. The aluminum wheels will compress more than the actual lugnut.

Anyway, to answer your question, I use around 85lb/ft just to be safe.

 

Thanks guys for the responses!
