Any "between the tires" chocks like x-chocks, Rotochocks, etc will loosen as the tires cool down and contract.
After setting them when you first park, it's a good idea go go back after the tires have cooled and then adjust them tighter.

Rotochocs are the best. The trailer tires would skid along rather than turn if you tried to pull the trailer without removing them.
Best chocks ever made, in my opinion. Unfortunately, the company went out of business a few years ago after the original owners passed on.
