| Recommended tire pressure | The recommended tire pressure for the Case IH D45 tractor typically ranges from 9 psi for the front tires and 6 psi for the rear tires when using IF 800/70R38 tires; especially in heavy tillage applications. It’s important to adjust tire pressure based on load and conditions to optimize performance and reduce soil compaction. |
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.
