turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
115 Nm.
Tightening torque for steel wheels:
● 15" steel wheel bolts should been
tightened with 100 Nm.
● 16" steel wheel bolts should been
tightened with 115 Nm.
Use the correct wheel bolts for the
respective wheels.
