Does anyone know the proper lug nut torque setting for the 18" BBS Milan Wheels? Can't seem to find it through a search, want to make sure I use the proper setting. Thanks.

 

I do my Pentas at 75...

 

Thank you. 75 seems low for lug nut torque, but glad I asked. Shouldn't be any difference with the BBS wheels I suppose. Thanks again.

 

75 Lb.Ft (100 NM) is about the torque specified for most M12 wheel bolts or nuts. The only M12 wheel bolts that I have seen requiring a bit higher torque (110 NM or 81 Lb.Ft) are the wheel bolts on my Saab 9-5.

I happen to have a Ferrari 348 which uses thicker M14 wheel bolts. The factory specified torque for these is 80 Lb.Ft, some recoment 90 Lbf.Ft.

So, I wouldn't go much more than 75 Lb.Ft on Jag lug nuts.

 

I love me a 348! TS or TB? I was surprised when I saw the torque spec for the lugs on the x308. Expected them to be higher, but no.

 

It's a 348 TB. The wheel bolt/nut specified torques can sometimes cause suspicion that they are insufficient. Probably because you feel, using the fairly long wheel spanner, that you can fairly easily tighten them more by hand (after torqued to 100 NM). This is not the way to judge the wheel nut/bolt tightness. For M12 nuts/bolts (Jag), the specified torque of 100 NM is actually already very close to the maximum torque for M12, grade 10.9, fasteners which is 115 NM.

I'm sure that Jag wheels will not fall off if torqued at 100 NM (75 Lb.Ft). Going significantly higher than this can just cause deformation at the wheel holes.

I think the idea is that even a weak person should be able to change a wheel and torque the bolts OK. Those who are gorillas may need a torque wrench to stop any excess

 

This is from the Shop Manual circa 1999:

Yes...and remember...you have five of these on your wheel so there is quite a bit
of force being applied.
