In the case of the 2022 Mercedes-Benz E300, which has lug bolts for the rims, we need to use the BONOSS BL series wheel spacers for installation. To fix the vehicle with the lug bolts, proceed as follows.
Stop the vehicle and ensure that it is in first or P gear and that the handbrake or electronic handbrake is on.
Loosen the lug bolts on the front wheel side in a diagonal sequence using crossed spanners, but do not remove them completely.
Placing jack stands to support each end of the car would be a better safety measure.
Remove all lug bolts on the front wheel side using a crossed spanner. Remove the rim from the front wheel.
Look at the wheel assembly for stains or rust, you can use a degreaser to clean the brake discs. Remove any rust and dirt from the wheel hub with a rag. Widen the entire surface to ensure it is smooth. This is because all of that surface may cause the wheel spacer to not fit perfectly with the hub.
Match the holes in the wheel spacer to the bolt holes in the car. You can check that the wheel spacer is firmly seated and flush with the wheel by gently shaking it. Put a wheel hanger into the brake rotor hole.
Install the front rim and then reinstall the extended lug bolts. Use a crossed spanner to tighten them on the wheel spacers (install in diagonal order). Make sure they are secure but do not tighten the lug nuts completely.
Remove the jack stands. Slowly lower the car until the tires fully touch the ground and remove the jack.
Use a torque spanner to tighten the lug bolts to the specified torque. Always tighten them in a diagonal sequence. This will ensure that the lug bolts work.
Threads are correctly and securely seated. (Do not use an impact spanner)
Repeat the above steps.
After installing the full-wheel spacers, drive slowly back and forth, making sure the rims are turned a few times. Then turn off the engine and re-tighten each lug bolt with a torque spanner to the specified torque value. Ensure that all lug bolts are in good working order.
BONOSS recommends checking the use of the wheel spacers every 6 months and checking the operation of the vehicle to ensure safe driving.
After installing wheel spacers you can find small changes in the side of the tire and the fender. For most cars, wheel spacers within 3mm-20mm are feasible, and in the pursuit of aesthetics, BONOSS recommends a state where the tire is flush with the fender. Excessive tire protrusion may cause friction with the shoulder of the road and damage the wheel and tire.
