Recommended tire pressure
The recommended tire pressure for a Yanmar SA223 depends on the specific tire size and load; but typical rear tire pressures for similar compact tractors range from about 15 to 25 psi when carrying moderate loads; while front tires are often set lower for better traction and ride comfort.
Before buying replacement tires
Match the complete sidewall size, rim diameter, axle position, 2WD/4WD configuration and tire type before ordering. On driven front axles, changing overall tire diameter can upset the required front-to-rear rolling ratio.
