2007 Volvo XC90 
holding on icy or snow-covered roads, we recommend suitable winter tires\
 on all four wheels. 
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and 
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the 
vehicle's roadholding and handling characteristics.
Storing wheels and tires 
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed 
on their sides on the floor. 
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be 
suspended. CAUTION! 
Tires should preferably be stored in a cool, dry, dark place, and should\
 never be stored in close 
proximity to solvents, gasoline, oils, etc. 
Tread wear indicator 
The tires have wear indicator strips running across or parallel to the t\
read. 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 indicate 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.
