Recommended tire pressure
There isn’t a single fixed PSI for a Yanmar YM226 tire; you should follow the maximum pressure printed on the tire sidewall and avoid going so low that the tire can slip off the bead or the wheel can cut into the tire. Many people aim lower for light loads (often around 6–8 psi) and go higher for heavy loader work (often 20–25 psi); but your correct number depends on your tire size and load.
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.
