17.5R25 55 NOTE: These are general pressures. For applications such as slope and ditching service, the inflation pressures should be increased by 100 kPa ( 15 psi ) with NO increase in carrying capacity.Any extreme conditions should be referred to your local tire supplier OR representative for recommended pressures, sizes, patterns, and compounds for specific application.The recommended inflation pressures provided are a starting point for the machine shown.
