Tires – Tread Wear Indicator - Volvo XC60 Owner's Manual

WHEELS AND TIRES
Tires – tread wear indicator
The tires have wear indicator strips running
across or parallel to the tread.
The letters TWI are printed on the side of the tire.
When approximately 1/16" (1.6 mm) is left on
the tread, these strips become visible and indi-
cate that the tire should be replaced. Tires with
less than 1/16" (1.6 mm) tread offer very poor
traction.
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and size
as the one being replaced. Using a tire of the
same make (manufacturer) will prevent alteration
of the driving characteristics of the vehicle.
