5) Fitting a new wheel
Position the summer wheel in place and slightly tighten the nuts by hand to make sure the thread is lined up properly. This way, you can avoid a crossed thread. Also make sure to always use the right nuts. Depending on the rim and car model you must use nuts with a conical or spherical collar. If uncertain, ask an expert for advice.
If the wheel is not flush on the hub it can result in a tyre imbalance at high speed (see STEP 5). Therefore, make sure if centring rings are required as an installation aid. Centring rings compensate for the difference in hub diameter between rim and car.
Tighten all nuts cross-wise by hand using a wheel wrench. For example: Start with the lower left nut, continue with the upper right, then the upper left and lastly the lower right.
Now it’s time to use the torque spanner:
Check the certification for the right torque and tighten the nuts accordingly.
After having fitted the wheels, check the air pressure of the tyres. Not sure how that works? Check out STEP 5.
Tighten nuts one more time roughly 50-100 km after the tyre change. This will help avoid nuts from loosening up and posing a risk to driving safety.
