Question: what tyre pressure for tractor?
Answer: A look across the chart reveals that, with the pressure set at 11.5psi, this tyre is allowed to carry a maximum of 3150kg when travelling at 10kph. Increase pressure to 23psi and its load can be 4355kg at 10kph, increase speed to 40kph with 23psi tyre pressure and the maximum load allowed reduces to 3350kg.
