Wheel bolt / Lug Nut Torque setting / tightness

I searched and found something suggesting M12 nuts should be 140Nm and M14 should be 140Nm.

I've just checked the idrive manual in my g30 and it says 140Nm. But I thought the g30 had M14 nuts...?

Just switched back to summers. I have to say the Halfords advanced torque wrench was excellent. My old extendable wrench (non torque) was basically causing some minor scratches in the hole. Advanced one is strong straight and let's me know exactly when the right tightness is achieved! Can't believe I waited this long to get one!

Oh and also - I swapped wheels that have never been on my car before and the car just recognised the tpms sensors and now gives the readings of the summer wheels. Awesome!

Like you said, it's 140Nm torque for the M14 bolts.

D'oh! I meant to type 120 for the M14. At least that's what the post said. Anyhow. Time to bow out now...

Thanks.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."

Not according the BMW manual. M14x1.25 is correct, but the manuals for G30 2018 and 2021 say 101 lb ft/140 Nm.
