In which of the following circumstances relating to tires does the vehicle's fuel consumption increase?

Question

DentroTest · Accepted Answer

Driving with an inflation pressure lower than the one specified by the manufacturer increases rolling resistance. With too little air, the tire deforms more against the asphalt and forces the engine to make a greater effort to keep moving, which raises fuel consumption. In addition, insufficient pressure accelerates uneven wear of the tire shoulders and raises its internal temperature, with the risk of a blowout. Driving with the pressure prescribed by the manufacturer is, on the contrary, what optimizes performance and minimizes consumption. Inflating with hot air is not what raises consumption either: what matters is that the resulting pressure is lower than the recommended one.
