Proper tire inflation is crucial to prevent accidents due to the size of the tire and ______ placed upon them.

• A. Load
• B. Weight
• C. Pressure
• D. Force

Answer: (A)

Tire safety hinges on matching inflation to the load the tire must carry. The tire’s size determines how much of the vehicle’s weight is supported by that tire, and as the load increases, maintaining the proper footprint and heat management depends on inflating to the recommended pressure for that load. Underinflation causes excessive flexing, heat buildup, and faster wear, while overinflation reduces the contact patch and can worsen handling. Because the factor being described as placed upon the tire is the load being carried, the correct word to complete the sentence is load. Weight and force are related ideas but aren’t the standard term used in tire inflation guidance, and pressure is the setting you choose, not the entity placed on the tire.
