What is the suitable tire pressure for small cars in summer?

[Naomi]

In summer, the most suitable tire pressure for small cars is 230kpa. The following are the effects of tire pressure on the car: 1. High tire pressure: Saves fuel, makes steering lighter, but excessive tire pressure reduces the contact area between the tire and the ground, causing a sharp increase in wear per unit area, which can easily lead to loss of braking control, tire bursts when encountering road protrusions or depressions, damage to the car's suspension system, and uncomfortable rides. 2. Low tire pressure: Shortens braking distance, provides better grip when turning, but low pressure makes the car consume more fuel, steering feels heavy and underpowered when turning. At the same time, severe deformation of the tire sidewall accelerates the aging of the internal steel cord layers, creating a hidden risk for tire bursts, increasing fuel consumption, and reducing tire lifespan.
