Torque

The manual for my 2008 Sierra says to torque the wheels to 140 pounds. This seems like a lot to me... Do you guys go the full 140 or something less?

ALWAYS go with the 140. Make sure the face of your brake rotor and the face on your wheel that mate together are free from rust and are as clean as they can be. Nobody wants to lose a wheel!!!! Use the cross pattern tightening procedure shown in your owners manual. Do NOT just tighten them in a cloclwise or counter clockwise pattern!

If it's an older truck and those surfaces are kinda grungy, I torque the nuts, drive the vehicle 5 miles or so then re-torque just to be safe! Don't forget to back off the torque wrench adjuster to take the pressure off the internal spring. That keeps your wrench accurate. But you knew that..........RIGHT?

Wow, 140 seems awful high for an aluminum rim.

The torque value is usually determined from the size (diameter) and strength of the lug. Torquing places a uniform force on wheel to the axle lug disc face which prevents movement.

IMPORTANT - Check lug nuts for proper torque following 50 miles of driving.

Torque to spec, and then re-torque after 50-100 miles, just to be sure.

And yes, I came darn close to losing a wheel a couple years ago. Never again.

Great link, Z15! I had heard about not greasing the lugs on my boat. This helps explain why.

The wheels are 14", not 100% sure of the tire dimensions. The boat is currently in storage, but here it is-not the greatest picture. It's a 2005 Sea Ray 185.

Not sure what you were going for, but I obviously fell for it. I try not to post just to post stuff, but if my post regarding lubing lug nuts was irrelevant, my apologies.
