6-3 DIY Maintenance 233
■ Check to see whether tires are
scratched, punctured and worn
every time when checking the
inflation state of tires.
● Damage to and swelling of tire
tread or tire wall. The
corresponding tire should be
replaced if any of these
phenomena is found.
● Scratches, cracks or fracture
on the tire wall. The
corresponding tire should be
replaced when the tire cord
fabric or cord thread can be
seen.
● Excessive wear of tire tread.
■ A wear mark is provided inside the tire tread. When the tire tread is worn to
this mark, the strip sign means that the thickness of tire tread is less than
1.6 mm. A tire worn to this degree has very small adhesive force on a wet
and slippery road.
■ When the tire tread is worn till exposure of the wear mark, there will be
much loss of tire performance and the tire should be replaced.
■ In addition to proper inflating, correct wheel alignment is helpful to reducing
wear of tire tread.
■ It is recommended to drive the vehicle to a BYD authorized service provider
for checking the wheel alignment status if any uneven wear of tire is found.
■ Balancing of tires has been done before delivery of the vehicle. However,
re-balancing of tires should be carried out after a certain period of vehicle
running.
■ If you feel a kind of continuous vibration when driving the vehicle at a high
speed (80 km/h), but do not feel such vibration when driving at a low speed,
it is recommended to drive the vehicle to a BYD authorized service provider
to check tires.
