Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down
whenever there is rain, snow or ice on
the road to reduce the possibility of
losing control of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn uneven‐
ly, have a professional workshop check
the wheel alignment. Kia recommends
to visit an authorized Kia dealer/service
partner.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always
be rebalanced if it is removed from the
wheel.
Tire sidewall labeling
This information identifies and de‐
scribes the fundamental characteristics
of the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a re‐
call.
