Tires are designed (wouldn't trust China bombs) to handle the ambient temperatures. The psi will increase as the tires heat up. That is one of the reasons the sidewalls indicate a cold psi. Our G114 H rated tires with a cold psi of 120 will get up to 145-148 psi while traveling in the summer heat. Don't let out air on a hot tire to meet the proper psi or you will be under-inflated.
