Tire Information
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 below. If you do
not adjust the tire pressure,
excessive heat can build up and
cause sudden tire failure.
