Recommended tire pressure
The Zetor Forterra 135’s recommended tire pressure varies by use: about 0.8 bar (11.6 psi) in the field and 1.4 bar (20.3 psi) on the road when using a Agropressure calculator; without a Central tire Inflation System; use the higher road pressure to avoid under-inflation risks.
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.
