Wheel Lug Torque Requirements
Merry Christmas to my fellow M3 reprobates.
What is the proper lug torque for the OEM 19s? Wife gave me an Omega Planet Ocean Chronograph, but I'm getting a refund and buying a set of HRE P40/PS2s. Thanks Last edited by 335 S; 12-26-2009 at 04:19 PM.. |

No anti-sieze on the threads is a very important detail many users overlook. (it changes the torque spec) Threads should always be torqued DRY.

Excellent pic to show the pattern of how wheel bolts should be properly tightened.
I've seen it done improperly by several tire & wheel installation shops over the years.

No. Ground is better IMO, even with air tools; just have the lug bolts snug before lowering car. Weight of the car rests on the hub's 'ring', not on the bolts themselves. And rubber is flexible for the minute movement after tightening. Actually, I've never seen anybody tighten wheels to spec in the air in my 47 years. Plus you'd need somebody inside the car to put the brakes for the front wheels on RWD cars, especially without air tools. No need to be that anal .
And the opposite when removing a wheel: loosen bolts on the ground and snug them back until wheel is in the air. And it's best to tighten them to spec in 2 steps, both times in a criss-cross pattern. I do 45 and 85 on the M3, and 40/80 on all others. Take care. |
