Chery A1 2008 Operating Instructions Manual page 139

In relevant laws and regulations, wear
depth of tread has been restricted. Note
that when the wear depth reaches the limit
of 3mm, a wear band will appear on the
thread, which indicates
performance and safety of the tire has
been badly reduced at the time and it must
be replaced.
Please observe local provisions
on environmental protection to
dispose the worn tires. Once road status
permits, immediately replace the tires for
winter with the ones for summer. This can
reduce fuel consumption and noise.
Replacing Tire
The tires used on your vehicle have been
properly selected to provide optimal
operating control performance, comfort
and safety of vehicle. Above combination

tire or refer to the advices of a Chery
Authorized Service Station when installing

The speedometer will be affected by the
