Car tire 91v indicates that the tire has a load index of 615kg and a speed rating of 240km per hour. The following are the effects of overloading on tires: 1. Severe overloading or uneven loading of the vehicle: This can cause the tire to operate under extreme load, increasing the bending deformation of the tire sidewall, expanding the contact area with the ground, accelerating tire wear and damage, and making it prone to tread blowout when encountering obstacles. 2. Hazards: Overloading and exceeding limits of vehicles seriously endanger the lives and property safety of the country and the people, induce a large number of road traffic accidents, and cause huge losses to people's lives and property due to overloading and exceeding limits in transportation.

What to Do When ESCL Malfunction Prevents Starting the Car?

ESCL malfunction preventing car startup can be caused by issues such as vehicle pulling to one side and heavy steering. Below are detailed explanations of these problems: Vehicle Pulling to One Side: While driving, the steering wheel remains centered, but the car automatically drifts to one side. Causes include uneven tire wear or pressure differences, inconsistent front wheel alignment parameters, bent or deformed steering rods with excessive play, unequal spring force or excessive deformation in the front suspension coil springs, and worn wheel hub bearings with large gaps. Heavy Steering: Turning the steering wheel left or right feels very strenuous. Reasons include incorrect front wheel alignment, underinflated tires, deformed or worn steering linkage, tight ball joints, and insufficient lubrication in the steering gear.

Why Was the Changan Ouliv Discontinued?

Changan Ouliv was discontinued due to safety hazards and low sales caused by its relatively high price. Below are the detailed reasons for the discontinuation of the Changan Ouliv: Safety Hazards: Some Changan Ouliv vehicles experienced abnormal wear on the torque sensor of the steering shaft assembly after prolonged use, causing the controller to enter a fault protection mode. In extreme cases, this could lead to reduced power steering assistance and heavier steering, posing safety risks. Starting from March 1, 2017, Changan recalled 108,642 Ouliv vehicles manufactured between November 7, 2012, and November 13, 2015 (inclusive). Low Sales: Low sales resulted in low ownership rates, driving up the cost of parts and repairs, with many components becoming difficult to obtain. Additionally, the vehicle's front-end design somewhat resembled that of a small SUV, leading to larger blind spots around the A-pillar and relatively high fuel consumption.

Can You Lock the Car with Windows Open?

You can lock the car with windows open. Below are relevant introductions about open windows: Solutions for open windows: Vehicles can be equipped with some safety features, such as automatic window roll-up, which closes the windows automatically after locking the car, or safety driving modules like Car Intelligence. These can effectively detect vibrations or collisions after parking and promptly report them to the owner via SMS. Many car models emit an alarm sound when locked if opened without the remote control. Impact of open windows: It is recommended to close the windows before locking the car to reduce the risk of property loss. Mechanical locking systems (using car keys to lock doors) do not assess the state of the windows, and electronic locks previously did not consider the windows. Now, electronic locks automatically close the windows after locking the doors.

Can You Start a Car While the Battery is Charging?

You can start a car while the battery is charging, but it may be difficult to start the vehicle during the initial charging stage. Below is relevant information about car batteries: Reasons for Difficulty Starting the Car: When starting the engine, the high current required mainly comes from the battery itself. When the battery is not fully charged, it cannot provide sufficient starting current, making it difficult to start the car. The charger has a current limiting function. When the battery voltage is very low (during startup), the charger's current is limited to a certain range to prevent overload and damage to the charger. Battery Maintenance Methods: It is best to use a battery charger and charge it correctly, with safety as the top priority. If the car is not started for a long time, the battery clamps should be removed, and the battery should be sent for charging periodically.
