Lower your air pressure, on my gc I have them around 14-15 psi.
ThanksHad turfs on the first series 2 JD. Had LOTS of front tire problems. Have had R4s on the 1025R and now on the 2025R. No tire problems at all. Yeah, a bit harder riding. Haven't tried lowering the pressure on the rear ones. Was suggested to another OP who brought this up. DO NOT lower pressure on the front ones though.
