NOTES: 1: Figures in parentheses denote ply rating for which bold face loads and inflations are maximum.
2: Maximum shipping pressures are the maximum inflation pressures for the tire sizes and ply ratings shown.
3: For above tires used in cyclic loading service (excluding hillside combines) with speeds up to 5 MPH, above loads may be increased 67%. This load increase applies to vehicles that operate up an 11° slope (20% grade).
4: Tire load limits at various speeds with no change in pressure are shown to the right.


MAX. SPEED

% CHANGE IN ABOVE
10 MPH / 15 KM/H +50% (except hillside combines)
15 MPH / 25 KM/H +28% (except hillside combines)
20 MPH / 30 KM/H +11%
25 MPH / 40 KM/H SAME
30 MPH / 50 KM/H -9% (F-3 tires only)
