If the tire's maximum recommended pressure is 100 psi, what pressure should you use according to the guideline?

• A. 90 psi
• B. 100 psi
• C. 105 psi
• D. 95 psi

Answer: (D)

Tires have a maximum pressure set by the manufacturer, and the guideline is to inflate to a level just under that limit to balance control, ride comfort, and safety. Since the maximum is 100 psi, the recommended target of 95 psi stays under the limit while still providing solid support and handling. Inflating to 100 psi reaches the limit and can be too stiff for many conditions, and 105 psi would exceed the maximum and risk a blowout. A value like 90 psi would be underinflated for typical loads and conditions, giving less support and traction.
