Checking the Tire Pressure
Service Interval:
Every 25 hours—Check the tire
pressure.
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause an uneven
cut. Check the pressure at the valve stem when
the tires are cold to get the most accurate pressure
reading.
Inflate the front tires to 103 kPa (15 psi).
Inflate the rear tires to 138 kPa (20 psi).
