Lug nut torque...what value do YOU use?

[eddiebx]

While rotating my tires today, I stumbled upon an interesting issue in the FSM.

One section of the FSM calls for a torque value of: 97 ft-lbf

Another section of the FSM calls for a torque value of: 83 ft-lbf

And finally the owner's manual calls for a torque value of: 81 ft-lbf

To the lay person like me, it seems like ~97 ft-lbf might be a bit overkill since the studs don't really look any thicker than passenger car studs? I recall most of my hondas and toyotas with similar diameter studs being ~80ish ft-lbf...

Personally I've always torqued my lug nuts to ~84 ft-lbf on the 4runner and called it good, but I'm curious about how tight you guys like to twist yo nuts?

I snapped 1 lug stud off torquing to 85 ft-lbs and another lug was stretched and ready to snap.

Fortunately the studs were easy to replace. Too bad they are so weak.

I never snapped a stud on my 12yr old 2nd gen Tacoma with the same torque values.

I'm not doubting you had issues but you have got to be kidding. That's what most people torque at. That's ridiculous. It's pretty much average. I could see stretching and busting off studs at over 100. But since they already suggest 83. It's almost hard to believe that 85 would be over torquing.

Just got back from a Tire Shop

Tighter is not always better! You will stretch and eventually break 5th Gen lugs at that much torque. Many have proven that already.

Good Luck!

1st of all Everyone, this is a really old thread!!!

Just got home from a major tire shop in town and they used impacts to tighten my lugs??

I've been searching my manuals then went to the internet to find an answer to lug nut torque specs. Came on to this thread.

Antman... I completely respect your opinions. Whenever you comment, I listen.

I totally agree with what you said here but want to add for those listening to me: MOST fastener/clamp load failures, particularly those in a dynamic state are due to an "Under Torque" condition. Too loose.

We can talk about going beyond the elastic state of a fastener. I think Antman gets this.

I'm hearing 85Ft/lbs for a 5th Gen. Does that still hold true for a 2021?

Have torque on the ground and ready to do the do over.
