When it comes to the 2022 BMW 7 Series wheel bolts size matters, replacing the wheels or adding wheel spacers could affect the length in several ways. For example, the wheel’s center hub is designed to be thicker than the car’s original set. This could have a negative effect on securing the wheels by reducing the necessary thread engagement area. In this case, if you get new aftermarket wheels, you would probably need a little longer 2022 BMW 7 Series wheel bolts to fit.

Eventually, wheel spacers will reduce the thread area of the OEM bolts even more. For wheel fasteners, the length engagement (i.e., the number of threads that are engaged between the bolts and the threaded nuts) has to be adapted to respect the criteria. Therefore, when you add wheel spacers, a set of proper longer 2022 BMW 7 Series wheel bolts is standard hardware you would need.

How Do I Know What 2022 BMW 7 Series Wheel Bolts Do I Need?

It is easy to figure out what length of 2022 BMW 7 Series wheel bolts you need. Simply add the extra length to the OEM ones. For example, if the OE wheel bolt length is 27mm and you get a 12mm wheel spacer installed, then you would need longer wheel bolts with 39mm length (stock bolt length + spacer thickness = extended wheel bolt length).

If you need to fit aftermarket wheels, just take off one OEM wheel and a stock bolt. Place the stock bolt pass through the lug hole of the OEM wheel, measure the exposed thread part and write it down. And then use the same bolt to go through the lug hole of the aftermarket wheel, also measure the exposed thread part length and write it down. Assuming that with an OEM wheel, you get 20mm and with an aftermarket wheel, you get 15mm. Then you would need 5mm longer 2022 BMW 7 Series wheel bolts.

How to Measure the Length of 2022 BMW 7 Series Wheel Bolts?

It is not difficult to figure out how long the 2022 BMW 7 Series wheel bolts you need. But the question is, how do I know the length of my OEM wheel bolts? Unless it is specifically mentioned on the owner’s manual how long the OEM wheel bolts can be used with your new wheel, it’s important to always re-measure your bolts.

  1. Measure the whole length of your 2022 BMW 7 Series wheel bolt;
  2. Measure the thread length of your lug bolt;
  3. You want 15mm of the exposed stem in order to properly secure your aftermarket wheel or spacer to the hub.

Example:
27mm lug bolt + spacer thickness (15mm) = 42mm wheel bolt, and the thread length should be as same as the OEM ones.
The additional thickness of the mounting pad (5mm) + 27mm = 32mm (which is the proper size lug bolt you would need for your new aftermarket wheel).
