We likewise upgraded tires although ours are Maxxis.
Maxxis advised us that the pressure on the tire is not necessarily the required pressure, it is just the maximum pressure the tire is rated for.
Most mfr's publish a pressure vs load table for their different size and rated tires. Ironically though, Maxxis acknowledged the table but cautioned me to add 10-15 PSI to the number in the chart "just to be safe".
