Check Air Pressure In Tires
The center two tires require more air pressure than the
wing tires. Too much air pressure in the wing tires will
cause the wings to bounce excessively in the field.
Check psi ratings of all four tires. Add or remove air as
needed until the tires are at the correct psi rating. See
“Tire Inflation Chart” on page 26 for psi ratings.
