What is the normal range of tire pressure?

[SanAdaline]

Car tire pressure normally ranges between 230-250kpa. Cold tires and hot tires have different pressures, with hot tires being about 20kpa higher than cold tires. Standard tires have a pressure of 240kpa-250kpa, while reinforced tires have a pressure of 280kpa-290kpa. Additional information: Regularly checking tire pressure ensures safety: 1. Before driving, inspect the tire condition. Radial tires—commonly known as low-pressure tires—are normal as long as the aspect ratio is not too low; if they feel very elastic when pressed with your foot and not too soft, they are fine. 2. High-pressure tires: These refer to bias-ply tires with inner tubes. Viewed from the front, the shoulder area should not protrude, commonly referred to as "not bulging." Viewed from the side, the contact area with the ground should be similar to normal. 3. While driving, pay attention to the sound of friction between the tires and the ground, the cushioning force when driving over uneven roads, and whether the acceleration feels different from usual when pressing the gas pedal.
