What are the direct consequences of driving with a tire inflation pressure lower than the recommended one?

Question

DentroTest · Accepted Answer

Driving with an inflation pressure lower than the one indicated by the manufacturer has consequences for the safety and the economy of the vehicle. With too little air, the tire undergoes greater flexing and deformation in its structure, which produces excessive overheating and accelerated, uneven wear, concentrated mainly on the shoulders (the sides) of the tread. That greater deformation raises the rolling resistance, forces the engine to make more effort and increases fuel consumption. In addition, the risk of the tire coming off the rim and of a blowout grows. That is why it is false that insufficient pressure has no negative effect or that it is advisable on urban roads: it is always harmful. And it is also wrong that it reduces consumption and improves grip, because consumption goes up and dynamic behavior gets worse.
