Should Car Tires Be Deflated in Summer?

1 Answers
DiArabella
07/30/25 6:04am
If the cold tire pressure is higher than the manufacturer's recommended standard tire pressure, then deflation is necessary; if the cold tire pressure is still below the standard tire pressure, do not consider deflation but rather add some air. The general principle is to maintain the manufacturer's recommended standard tire pressure, without deliberately increasing or decreasing it, as both overinflation and underinflation can have negative effects on the tires. Specific information is as follows: 1. Manufacturer's regulations: Under normal driving conditions, even in hot summer, simply inflate the tires according to the manufacturer's specifications, and there is no need to reduce the tire pressure on your own. 2. Cold and hot tire pressure: Cold tire pressure refers to the tire pressure when the car has not been driven. Hot tire pressure refers to the tire pressure after the car has been driven for a long distance.

What causes the DEF warning light to illuminate in JMC Shunda?

JMC Shunda DEF warning light illumination may be caused by: engine overheating alarm; damaged water temperature sensor; or insufficient antifreeze. The DEF warning light in JMC vehicles indicates the auxiliary water tank warning light. When this light illuminates, it means the auxiliary water tank is low on water and requires immediate refilling to resolve the issue. Below are additional details: 1. Auxiliary water tank location: The auxiliary water tank is located beneath the driver's seat. Remove the seat cushion and the square metal plate to reveal a rectangular plastic container. For vehicles equipped with power steering, there's also a round plastic reservoir containing hydraulic fluid nearby. 2. Auxiliary water tank function: The primary purpose of the automotive auxiliary water tank is to accommodate expanding coolant when engine temperature rises, with excess antifreeze flowing into the auxiliary tank through the radiator cap. When temperatures drop and cooling system pressure becomes negative, the system draws antifreeze back from the auxiliary tank into the cooling system through the radiator cap. The auxiliary tank features marked levels indicating fluid quantity.

What is the speed limit and safe distance to maintain when visibility is 200 meters on the highway?

First, turn on the fog lights, low beam lights, clearance lights, and front and rear position lights. When visibility is below 200 meters, the speed should not exceed 60 kilometers per hour, and a distance of more than 100 meters should be maintained from the vehicle in front in the same lane. When driving on the highway and encountering low visibility weather conditions such as fog, rain, snow, dust, or hail, if the visibility is less than 100 meters, the speed should not exceed 40 kilometers per hour, and a distance of more than 50 meters should be maintained from the vehicle in front in the same lane. When driving on the highway and encountering low visibility weather conditions, if the visibility is less than 50 meters, the speed should not exceed 20 kilometers per hour, and the vehicle should exit the highway from the nearest exit as soon as possible.

How Much Fuel Does a Car Consume When Running the Air Conditioner for One Hour?

Generally, a family sedan consumes approximately 2 liters of fuel per hour when running the air conditioner, which translates to a range of 1 to 3 liters. There is no precise, standard, or uniform answer to this question, as it is influenced by numerous objective factors. For instance, fuel consumption differs between idling and driving conditions when the air conditioner is on for an hour. Additionally, the results may vary depending on the vehicle model. Below is relevant information regarding fuel consumption: 1. Overview: Fuel consumption typically refers to constant-speed fuel consumption, which is the standardized fuel consumption per 100 kilometers measured under specific constant-speed driving conditions as stipulated by national standards for certain types of vehicles. 2. Testing Methods: The test can be conducted either on the road or using a chassis dynamometer, with the fuel consumption per 100 kilometers calculated via the "flow meter method" or the "carbon balance method."

How Many Drain Holes Does a Sunroof Have?

A car sunroof has four drain holes. The drain holes of the sunroof are located near the A-pillar at the front of the sunroof. To locate the drain holes, you need to open the sunroof. Inside each drain hole, there is a tube that runs through the A-pillar, allowing water from the sunroof to flow out to the underside of the car. If the sunroof drain holes become clogged, it can lead to water leakage through the sunroof. Sunroof leakage can cause malfunctions in many of the car's electronic components. To prevent clogging of the sunroof drain holes, it is advisable to clean the dust around the drain holes during maintenance. To check if the sunroof drain holes are clogged, simply open the sunroof and pour a small amount of water onto the sunroof track. If the water drains out smoothly, the drain holes are not clogged. After draining, water will appear below the front fender of the car. If the water does not drain out smoothly, it indicates that the drain holes are clogged, and immediate repair is necessary to prevent water leakage during rain.
