An alternative to the 600/55-26.5 option is a 18.4-26 diamond pattern with matching fronts. There aren’t any diamond pattern front tyres, so we use the BKT hockeystick pattern
For the Case Farmall 55A, 65A, 75A we recommend a 400/55-22.5. Click here if you have a Farmall C as we recommend a different size front.
We recommend running them at the following pressures.
Rear 18.4-26 BKT 9psi
Front 400/55-22.5 15psi
