Types of tires
You should be familiar with type of tires
present on your vehicle. ! All season tires
The factory-installed tires on your new
vehicle except 2.5GT spec.B are all
season tires.
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by “ALL
SEASON ”and/or “M+S ”(Mud & Snow) on
the tire sidewall. ! Summer tires
The factory-installed tires on your new
2.5GT spec.B vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
