There are two load ratings you should be aware of Rolling Load capacity and Static Load capacity with static load capacity being the much more important one. Unless you're installing your tiles in a production facility with lots of forklifts and rolling carts, the rollover capacity is irrelevant. Most applications have the load such as your car, truck or toy sitting on them in a stationary fashion. As time cause on weaker tiles can compress and form static load indents.
