Correct answer
Pressure below that recommended for its load and use.
Pressure below that recommended for the vehicle’s load and use increases deformation and rolling resistance, which can raise fuel consumption and cause heating and abnormal wear. Check cold pressure according to manufacturer guidance and load; do not use a universal pressure or deflate a hot tyre to the specified cold value. Correct pressure must also be maintained for safety.
