Tires
Inflation
Keeping the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinflated tires can make your
vehicle ride more harshly, are
more prone to damage from road
hazards, and wear unevenly.
We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.

Recommended Tire Pressures for
Normal Driving
The following chart shows the
recommended cold tire pressures for
most normal driving conditions and
speed.
Tire Size Cold Tire Pressure
for Normal Driving
P185/70R14 87S 30 psi (210 kPa , 2.1
kgf/cm )
The compact spare tire pressure is:
60 psi (420 kPa , 4.2 kgf/cm )
Tire Pressure Adjustment for High
Speed Driving
Honda strongly recommends that
you not drive faster than posted
speed limits and conditions allow. If
you decide it is safe to drive at high
speeds, be sure to adjust the cold tire
pressures as shown in the next
column. If you do not adjust the tire
pressure, excessive heat can build up
and cause sudden tire failure.
Tire Size Cold Tire Pressure
for Speed over 100
mph (160 km/h)
P185/70R14 87S 35 psi (240 kPa , 2.4
kgf/cm )
