Your Class C RV weight range is limited and the recommended (sticker) tire pressures are based on the full GAWR. Your normal loading will be fairly close. The small difference between your required tire pressure and max allowed won't have a great effect.
Your weight limit for your tires, changes by 100-120 lbs for a 5 psi change in air pressure.
FWIW Tire pressure charts for the same tire size and load rating are identical. Chart pressures are the MINIMUM pressure required to support that weight.
My previous Class A motorhome had 22.5 inch tires with a sidewall limit of 120psi. My actual weight was well (5500 lbs) below max GVWR. Minimum required pressure was 85 front and 90 rear, ride and handling were noticeably affected by over-inflating to the sticker GAWR limits.
