Unit 21: Central Fill Corn Planter JD 1770 NT w 11-22.5 Bias vs VF295/75R22.5 Tires + JD 8320R Tractor

Plot Comments

  • This Unit compared a bias ply tire and a VF tire on the center section of a central fill corn planter.
  • Note that the tire pressures for this unit are similar and in fact the VF tire was inflated to a higher pressure which is not what would be expected.
  • To carry the load on the bias ply tire, the inflation pressure would need to be much higher. This was the maximum that the tire installers were willing to inflate for safety reasons. This bias ply tire is not suited for this application at this weight.
  • Interestingly the plots look almost identical.
