Mein Auto: '14 X5 50/ '10 Golf TDI
Wheels torque specs for 2012 550i xDriver GT

Not sure why BMW cannot include this in the manual. Our Golf TDI has wheel torque values in it's manual.

Searched and found another thread that stated "Factory spec on the GT is 140Nm, or 103ftlb" but that was for a 535i GT with sport rims.

Not sure if the 103 translates over to the 550ix GT with base 18inch rims. You think the 103 is universal across all 5 series GT models?

Thanks for the help.

I think that 140Nm is correct, but the safest thing is to call the dealer's service department. Since any of the GT's can have any wheels, it's more the hub/rotor spec than the wheel attached.

That seems high to me. I would definitely check it. A range of 86-92ftlbs is more "common."

It depends on the platform and the brake rotors. The GT uses a composite aluminum and steel rotor and aluminum expands and contracts more than steel, so some more tension is required to keep the bolts tight. I think you'll find the numbers I gave will check out with the dealer's service department. And, I agree, it should list that in the owner's manual!
