Torque Specs for wheel lugs

I felt the same way. I feel like I was probably applying double the torque required

I always loosen and re-torque my lug nuts after a trip to the tire store. I took my wrench with me a couple of times and got the strangest looks.

So this ties in nicely to my thread on cleaning up the lug nuts. Would the YouTube specs be the same on my 99 with 17" wheels, with putting anti-seize on the threads?

Older thread, but check out what they say on the torque when using anti-seize on stock lug bolts.

The real thing is....
The definition of torque is about having two equal and opposite forces that will cause a system to rotate.... the calculation of torque is the answer of a multiplication...which is the product of the pounds amount and the length of leverage...

but...people are not wrong to say lbs/ ft also , because you can say it in the opposite form, which would be : i will apply "x" lbs PER feet of leverage length. This is where all the confusion comes from.

To conclude...i would say that the exact specific torque value...with or without lube...is a kind of mental masturbation... these bolts have major safety factors so there is no way that any yield strenght would be reached for the difference that oil/grease or whatever else lube would do if you stay in a logical range of torque values...Just make sure you reach that value in an uniform, smooth and constant movement. The main objective is to torque them as less as possible, but as long as they will never come loose on their own.

I have a 19V Craftsmen Impact driver rated at 135 ft lbs , considering how over rated everything usually is I figure it is probably closer to 110 ft lb ...it is whet I use to remove tires and put them back on. Like some when I purchased a new set of tires last year I took the car home and had to stand on a breaker bar to get the lugs off as soon as I got home and then I put them right back on with the Battery Impact Driver.

Next time I buy tires I am taking the wheels in myself off the car.

The tire dealer won't be able to try and sell you a four wheel computer alignment, if you just bring in the wheels without the car!

Very common even at dealership level we would run into the same issues. I had to write techs up that did not torque wheels to get the point across, and even then the techs would slam the lugs hard and follow up with a torque wrench. Why even bother that point. But some actually think using a torque wrench is to make sure the lug nuts are tight! Its funny how something so simple cannot conveyed to some people.

I used to buy tires for my daily drivers at Costco, and the one I went to used a torque wrench to do the final tightening of the lug nuts.

Google is great for unit conversion. If you Google "nm to ft lbs converter" you get several sites that have you enter one number and it will convert it to the other unit.

Yes, that's why I included the conversion link in my post. I just want to make sure I'm doing the conversion correctly.

Somewhere between loose and stripped.

It's a German car, so best imho to get used to torque figures in nm (newton-meters).

130 nm

I've lots more Mercedes experience than Porsche experience, and Mercedes and BMW and many others forbid using lubricant (antiseize is lubricant) on wheel bolts. Porsche specification confuses me in this regard.

Awesome, 130 nm it is. Thanks!
