Maximum load on one tir Maximum load on one tire: e: maximum load on one
tire. This is calculated by dividing the maximum
axle load of one axle by two.
PSI (pounds per sq
PSI (pounds per squar uare inc e inch): h): standard unit of
measurement for tire pressure.
Aspect r
Aspect ratio: atio: ratio between tire height and tire
width in percent.
TTirire pr
e pressur essure: e: pressure inside the tire applying an
outward force to every square inch of the tire. The
tire pressure is speci ed in pounds per square
inch (psi), in kilopascals (kPa) or in bar. The tire
pressure should only be corrected when the tires
are cold.
Cold tir
Cold tire pr e pressur essure: e: the tires are cold when the
vehicle has been parked for at least 3 hours with-
out direct sunlight on the tires or the vehicle has
been driven for less than 1 mile (1.6 km).
TTirire cont
e contact surf act surface: ace: the part of the tire that
comes into contact with the road.
TTirire bead:
e bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel rim.
There are several wire cores in the tire bead to
prevent the tire from changing length on the
wheel rim.
Side w Side wall: all: the part of the tire between the tread
and the tire bead.
W
Weight of op eight of optional eq tional equipment: uipment: the combined
weight of the optional equipment weighing more
than the replaced standard parts and more than
5 lbs (2.3 kg). This optional equipment, such as
high-performance brakes, level control system, a
roof luggage rack or high-performance batteries,
is not included in the curb weight and the weight
of the accessories.
TIN (T
TIN (Tiriree Identi cation Identi cation Number): Number): a unique identi -
cation number which can be used by a tire manu-
facturer to identify tires, for example, in a product
recall, and thus identify the purchasers. The TIN is
made up of the manufacturer's identity code, tire
size, tire type code and the manufacturing date.
Load-bear
Load-bearing inde ing index: x: the load-bearing index is a
code that contains the maximum load-bearing
capacity of a tire.
Tr
Traction: action: traction is the grip resulting from friction
between the tires and the road surface.
W
Wear indicat ear indicator: or: narrow bars (tread wear bars) that
are distributed over the tire contact surface. If the
tire tread is level with the bars, the wear limit of
1/16 in (1.6 mm) has been reached.
Dis
Distrtribution of v ibution of vehicle occupants: ehicle occupants: distribution of
vehicle occupants over designated seat positions
in a vehicle.
Maximum per
Maximum permissible pay missible payload w load weight: eight: nominal
load and luggage load plus 150 lb (68 kg) multi-
plied by the number of seats in the vehicle.
