Tires
Temperature
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 condi-
tions on specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life,
and excessive temperature can lead
to sudden tire failure. 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 labora-
tory test wheel than the minimum
required by law.
Warning: The tire temperature grade
is established for a tire that is prop-
erly inflated and not overloaded. Ex-
cessive speed, underinflation, or ex-
cessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.
Winter Tires
You should mount winter tires on
your NSX before winter starts (before
consistent sub-freezing tempera-
tures). Change back to "summer"
tires after winter weather has
stopped.
Use winter tires on all four wheels.
The performance capabilities of the
winter tires may not be the same as
your car's original-equipment tires.
Check with the tire dealer for maxi-
mum speed recommendations.
The winter tire sizes are:
205/50R15 (front)
225/50R16 (rear)
Tire Chains
Use snow chains only in an emer-
gency or when they are legally re-
quired for driving through a certain
area. Use greater caution when
driving with snow chains on snow or
ice. They may have less-predictable
handling than good winter tires
without chains. Some snow chains
may damage the car's tires, wheels,
suspension and body. Consult your
Acura dealer before purchasing any
type of chains for your NSX.
