Final answer:
b. The maximum safe weight a tire can carry at a specified pressure. The load refers to the maximum safe weight a tire can carry at a specified pressure.
Step-by-step explanation:
In the context of car tires, the load refers to the maximum safe weight a tire can carry at a specified pressure.
For example, if a tire has a load rating of 1,200 pounds, it means that the tire is designed to safely carry up to that weight when inflated to the recommended pressure.
The load rating is an important specification to consider when selecting tires for a vehicle, as it ensures that the tires can support the weight of the vehicle and any additional load, such as passengers or cargo.
