Is it safe to drive with a tire pressure of 185?
1 Answers
A tire pressure of 185 is not safe for normal driving. Low tire pressure increases the contact area between the tire and the ground, leading to abnormal temperature rises inside the tire during driving. Additionally, severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, increasing the risk of a blowout. It also raises fuel consumption and reduces tire lifespan. Factors affecting vehicle tire pressure include: 1. Seasonal factors: In winter, it's advisable to slightly increase the tire pressure by about 0.2 bar based on the standard tire pressure. In summer, adhere to the lower limit of the standard tire pressure; for vehicles parked outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent blowouts due to high temperatures. 2. Load conditions: For empty or half loads, use the lower limit of the standard tire pressure (the tire pressure indicated on the vehicle's sticker can serve as a reference for the minimum pressure). For full loads, use the upper limit of the standard tire pressure (the maximum pressure marked on the tire can be a reference for the theoretical maximum pressure). 3. Tire pressure measurement environment: Cold and hot tires have different pressures, with a difference of about 0.3 bar, so measurement should be done accordingly. 4. Road conditions: On rough roads, it's appropriate to slightly decrease the tire pressure by 0.1-0.2 bar from the standard. For long-distance high-speed driving, the tire pressure should not be too low; it's advisable to slightly increase it by about 0.2 bar from the standard lower limit.
