lx 570 wheel torque
Typically in Canada the tire dealers ask you to return in 150km to "re-torque" the wheel lug nuts to make sure they are in spec. The reality is this is just a fail safe for dealers that don't do a proper job (jmho - hard to prove).
Anyway, I returned for my re-torque after the duratracs. The guy comes out with a really nice torque wrench, tests everything and says I'm fine ready to go. I ask what he torques to, and he replies "76...true for all toyota/lexus wheels". I say okey-dokey and drive away.
However, I seem to remember the manual specifies 97ft lb torque. I double check, and sure enough.
So today I stop in again. Same guy. He insists all Lexus and most toyotas are 76. He shrugs and goes to get the wrench. He sets it, and re-tests. I watch. NONE of the bolts move...not even one of them.
Conclusion: 1) we are wasting allot of time in Canada with the "re-torque" trips 2) the torque wrench re-test is USELESS...obviously the air tools are overtorquing ANYWAY...and a torque wrench doesn't test for that condition.
So really what SHOULD happen is snug all the lugs up. Then incrementally go up in torque until you hit the 97 evenly across all 5.
I doubt there is anything to worry about. I know over-torquing has risks, but I'm sure the LX has more then enough over-engineering to make up for it.

I always retorque mine whenever it has been in the shop. The problem I find is uneven and over tightening. At times I have to use a pipe cheater on a flex handle just to get the lugs loose. Of course, the result of this over tight and uneven tightening is warped brake rotors.

If it's a diy torque job, I simply divide total torque by 3 and torque in steps. Simple.

Tell your mechanic (tire changer guy) not all Toyota wheel have the same torque.
My LS 430 wheel nuts torque is 76 ft-lb, LS 600hL is 103 ft-lb. I have not check the my LX 570 book yet but as you have indicated it is at 97 ft-lb

Same with steel wheels on 14mm studs...152 ft.lb. Lug nuts for steelies are one piece with a conical end that seats on the countersunk stud hole.
I doubt an LS uses 14mm studs...hence the difference in torque.
