TSB: Porsche Wheel Bolts

This bulletin applies to 2022 and later Porsche Cayman, Boxter, 911, Taycan, Panamera, Macan and Cayenne vehicles. Modified wheel bolts were used in production during 2022. The wrench size of the wheel bolts was reduced from 19mm to 17mm and a surface coating was adapted. 

Mixing wheel bolts of wrench size 19mm and 17mm is not permitted. If there is a need for replacement, the wheel bolt corresponding to the original must be installed. Make sure that wheel bolt wrench sizes match the vehicle’s tool kit and rim lock. The thread size remains the same as does the tightening torque.
