This is correct, but I would do 90 also in case you have a cheap torque wrench or one that is out of calibration. More importantly than 87 or 90 is that you use a fluid, deliverate motion on the torque wrench. Don't jerk it.
Finally, on alloy wheels, you are supposed to re-check after a few miles....I can't remember but something like 100 miles. I put my stock wheels on my car on Friday torqued to 90 lb ft. Autocrossed all day Saturday then retorqued Saturday night and a few bolts turned a bit again. If you are leaving the wheels on for a long time, I also clean the hub and put a tiny, thin layer of anti-seize to keep the wheels from sticking from rust build up. |

I bought the BMW jack set. It came with a non adjustable torque wrench that says 140Nm. Is it gonna be a problem if I over tighten it to 140?

I checked other forum posts with pictures showing their torque wrench before I ordered mine. Their's is marked 130Nm. Granted the post was 2 years old. Mine looks exactly the same but is marked 140Nm, felt like I wasted money buying the kit now. I hope it's not gonna do anything funny to my wheels cos I have already torqued them to 140 last night.

140 Nm should be fine. It's probably that BMW has upped the torque spec for the wheel bolts. 140 Nm = 103 ft/lbs 130 Nm = 96 ft/lbs That is not a huge difference in specs. :-) |

103 ft/lbs is pretty far out of spec. The top of the tolerance range is 96 ft/lbs. Nothing is going to happen to your wheels but you will eventually fatigue the bolts to the point they will prematurely fail. I would losen and retighten to within spec. |

My understanding from the tire shop is that the nut or lug bolt nut diameter determine the torque lbs. The stock lugs with our 1M's requires a 90 lbs of torque.

140 is within the tolerance of the studs and rotors. For mental health reasons, loosen and retighten to the spec range. It won't have hurt anything, but no sense in worrying about it.

Also... when ever you torque your wheel bolts... ALWAYS recheck them 100kms or 60 miles after driving. Sometimes a wheel bolt can loosen after a wheel change. The reason is because sometimes the wheel isn't sitting completely flush with the hub when you tighten the bolts. Or rust on the hubs. Anyway... always recheck those wheel bolts!
