Example:
(6) Load Index: A numerical code
which specifies the maximum load
a tire can carry at the speed
indicated by its speed symbol, at
maximum inflation pressure.
For example, "90" means 1,323 lbs
(600 kg), "89" means 1,278 lbs (580
kg).
WARNING
Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire's rated
load.
(7) Speed Rating: An alphabetical
system describing a tire's capability
to travel at established and prede-
termined speeds.
For example, "V" means 149 mph
(240 km/h)
WARNING
.
Speed ratings apply only to
the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire's rated speed.
.
The speed rating is void if
the tires are worn out, da-
maged, repaired, retreaded,
or otherwise altered from
their original condition. If
tires are repaired, re-
treaded, or otherwise al-
tered, they may not be sui-
table for original equipment
tire designed loads and
speeds.
! Tire Identification Number (TIN)

individual elements.
