What is the optimal tire pressure for sedans?

1 Answers

The optimal tire pressure for sedans is 2.4bar, with the standard range being 2.4 to 2.8bar. In winter, it should be increased by 0.2bar, and in summer, decreased by 0.1bar to prevent tire blowouts. The hazards of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Decreased puncture resistance, increasing the risk of blowouts; 3. Accelerated wear on the central tread pattern, shortening tire lifespan and affecting other components; 4. Excessive stretching of tire cords, reducing elasticity and increasing the load on the vehicle during driving, further decreasing puncture resistance; 5. Increased susceptibility to punctures from nails, glass, and other sharp objects, leading to internal cracks and blowouts upon impact.

Is It Normal for Idling to Only Reach 4000 RPM?

This is a normal situation. Here are the relevant details. 1. Under normal conditions: A 1.5-liter displacement car can generally rev up to 5000 to 6000 RPM during idling, unless the vehicle's computer program is set to limit it to a maximum of 4000 RPM. There is no issue in actual driving, and this is considered normal. During regular driving, the engine speed is mostly between 1500 and 2500 RPM. 2. Internal reason: Vehicles are typically equipped with an idling protection function. The absence of this function would be abnormal. A 1.5-liter displacement engine should at least be able to rev up to around 6000 RPM during idling.
