These are P275/60-20 and are going on a LX570, right?
For 20" wheels, the Lexus recommended tires are P285/50-20 inflated to 33psi Front / 35psi Rear. This yields Load Limits of 2315 pounds in the Front and 2403 pounds in the rear.
For your P275/60-20 tires to have the same Load Limits, the recommended Cold Tire Inflation Pressures would be 28psi Front (Load Limit 2340 pounds) / 30psi Rear (Load Limit 2421 pounds).
Bottom line: 28psi Front / 30psi Rear
Based on new info, my original recommendation has changed to 33psi F/R. This retains the original "spring rate" of the OEM P275/50R21 tires @33psi F/R and provides a slightly higher Load Limit than specified for the Land Cruiser (2535 pounds vs. 2512 pounds).

@gaijin What is the recommended tire pressure for the LT275/60/20? I'm switching from the above P-rated to KO2s LT-rated in the same size.
