(Recommended cold tire inflation
pressure)
Front:
30 psi (210 kPa, 2.1 kgf/cm2 or bar)*
Rear:
30 psi (210 kPa, 2.1 kgf/cm
2 or bar)*
Spare:
60 psi (420 kPa, 4.2 kgf/cm
2 or bar)
*:When driving at high speeds above 100 mph (160 km/h), in countries where such
speeds are permitted by law, add 4.3 psi
(30 kPa, 0.3 kgf/cm
2 or bar) to the front
tires and rear tires. Never exceed the maxi-
mum cold tire inflation pressure indicated
on the tire sidewall.

Location of treadwear indicators (→ P. 390)
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is
a bias-ply tire.
“TUBELESS” or “TUBE TYPE”
A tubeless tire does not have a tube and air is directly filled in the tire. A
tube type tire has a tube inside the ti re and the tube maintains the air pres-
sure.
Load limit at maximum cold tire inflation pressure ( →P. 394)
Maximum cold tire inflation pressure ( →P. 493)
This means the pressure to which a tire may be inflated.
Uniform Tire Quality Grading
For details, see “Uniform tire quality grading” that follows.
Summer tire or all season tire (→ P. 395)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a
summer tire.
“TEMPORARY USE ONLY” (→ P. 466)
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded into its sidewall. This tire is designed for temporary emer-
gency use only.

ES350_U■
Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
