What is the appropriate tire pressure for small cars in hot summer weather?

[DelHarrison]

In summer, it is advisable to maintain the tire pressure at the lower end of the normal range, with 2.3~2.5 BAR being the most suitable. Below is an introduction to tire pressure: 1. Over-inflation: This reduces the friction and adhesion of the tires, affecting braking performance; it causes steering wheel vibration and deviation, reducing driving comfort; and accelerates uneven wear on the central tread pattern, shortening tire lifespan. 2. Under-inflation: This increases the friction coefficient with the road surface, leading to higher fuel consumption; it causes heavy steering and a tendency to deviate, which are factors detrimental to driving safety; it increases the movement of various parts of the tire, causing excessive rolling and abnormal heat generation; the friction between the tire and the ground multiplies, rapidly raising the tire temperature, softening the tire, and drastically reducing its strength, which may lead to a blowout when driving at high speeds.
