Mazda CX-9 2021 Manual page 603

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
6. (Vehicles with sub-woofer)
Secure the sub-woofer to the flat tire
using the flat tire belt.
1. Pass the flat tire belt through the
wheel of the flat tire.
2. Install the sub-woofer to the flat
tire.
3. Pass the flat tire belt through the
buckle.
