What Does Negative Wheel Offset Mean?

Negative wheel offset refers to the numerical value of the wheel's center offset, representing the deviation distance from the wheel's centerline to the wheel's mounting surface. Therefore, the larger the negative ET value, the more the wheel will protrude outward when installed on the vehicle. The term 'offset' can be seen in the middle position. Offset plays a crucial role in the performance of tires and wheels, as well as the overall performance of the vehicle. This is because offset affects the wheel track, which in turn influences the vehicle's stability and tire grip to some extent. Offset is defined as the difference between the wheel's center reference plane and the wheel's load-bearing surface (mounting surface), measured in millimeters. When the wheel's load-bearing surface is outside the center reference plane (from the perspective after installation), the wheel is a positive-offset wheel (most factory-installed wheels are positive-offset). The advantages of positive-offset wheels include safety, stability, and reduced additional air resistance since they are tucked inside the vehicle body. Conversely, when the load-bearing surface is inside the center reference plane, the wheel is a negative-offset wheel. The benefits of negative-offset wheels include widening the wheel track, providing better vehicle stability, and enhancing the lateral support capability of high-performance tires. However, negative-offset wheels typically protrude outside the vehicle body, creating additional air resistance and increasing the risk of scraping against external objects. Simply put, the advantage of negative-offset wheels lies in offering greater support during cornering. Wheel offset is often denoted as ETxx. For example, ET+30 means an offset of +3 cm, while ET-30 indicates an offset of -3 cm. Generally, the maximum positive offset is +50, and the maximum negative offset is -44. Most SUVs come with positive-offset wheels from the factory. Switching to negative-offset wheels widens the wheel track, improving vehicle stability.

How can beginners determine the blind spot in front of the car?

Generally, the area not visible in front of the car is the farthest position when the steering wheel is turned fully left or right. If the steering wheel is not turned to its maximum extent, you can also choose to measure the actual distance. Currently, the front blind spot for small cars should not exceed 2.5 meters. Below is more related information: Blind Spots: Generally, blind spots are divided into passive and active. Passive blind spots usually consist of 10 areas, located at the front, rear, both sides of the A-pillars, both sides of the B-pillars, both sides of the C-pillars, and the left and right rearview mirrors. Active blind spots include obstacles inside the car and high beams. The main blind spots of a vehicle are the front, rear, and both sides, each presenting different angles and varying degrees of danger to the driver. Judging distances while driving is a skill. During driving, you must rely on your experience to determine the vehicle's travel distance. When turning or navigating narrow spaces, you must judge where the tires are pressing. This relies entirely on experience, so it's best for beginners to have an experienced driver accompany them when driving on the road; otherwise, it can be challenging to handle complex road conditions.

Should You Release the Foot Brake First When Starting on a Slope?

When starting on a slope, you should not release the foot brake first. The correct operation for starting on a slope is as follows: First, slowly release the clutch until the engine starts to vibrate, then release the brake pedal, and immediately press the accelerator to follow up. Here are the methods for coordinating the clutch and brake: 1. Automatic transmission cars do not have a clutch pedal, so you can directly press the brake. 2. When driving at high speed or normal speed, you do not need to press the clutch to slow down. 3. When taking a curve, first press the brake to slow down. If there are no obstacles after the curve, you do not need to press the clutch; release the brake and press the accelerator to speed up. If there is an obstacle right after the curve, press the clutch and shift to a lower gear. 4. When going down a long or steep slope, do not press the clutch; use the engine's traction for braking. 5. When parking, first press the brake to reduce the speed, then press the clutch.

Does Car Insurance Cover Full Compensation for Water Damage?

If a car is submerged in water and the corresponding insurance has been purchased without performing a secondary start-up operation, the insurance company will provide full compensation. According to the provisions of the Home-use Automobile Loss Insurance Clause, during the insurance period, if the insured or their legally permitted user suffers loss of the insured vehicle due to natural disasters such as rainstorms or floods while using the vehicle, the insurance company will compensate as agreed. Procedure for claiming compensation after a vehicle is submerged in water: Vehicle water damage generally falls into two scenarios: first, when the vehicle is parked on the roadside or in an underground garage and gets submerged due to deep water accumulation; second, when the vehicle is driven into a waterlogged area, leading to water ingress, stalling, and inability to proceed. It is important to remain calm in such situations. Ensure personal safety first, then immediately report the incident by calling the insurance company where the vehicle is insured. Next, take photos. If the insurance surveyor cannot arrive promptly, the owner should take photos of the scene and the vehicle's damage condition safely for assessment and claims. Lastly, arrange for rescue services, either through the insurance company or a professional rescue company.

What is Subject 2 Simulation Training?

Subject 2 simulation is a practice that mimics the official Subject 2 driving test to improve the pass rate. The simulation covers the same test items as the official exam, serving as a trial run. Below are the relevant details: 1. Overview: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. 2. Test Items: For car licenses C1 and C2, the test includes five mandatory items: reversing into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-curve). Some regions may also include a sixth item, such as highway toll card collection. 3. Learning Objectives: Master the basic essentials of driving operations and acquire fundamental vehicle control skills; become proficient in basic methods of field and road driving within the test area; develop the ability to reasonably use vehicle controls and correctly manage the spatial position of the vehicle, ensuring precise control over the vehicle's position, speed, and route.

Can I renew my driver's license if it has expired for 20 days?

You can renew your driver's license if it has expired for 20 days. According to the regulations, if the license has been expired for less than one year, it can be renewed normally. The renewal and inspection must meet the following conditions: Holders of large passenger vehicle, tractor, city bus, medium-sized passenger vehicle, or large truck driver's licenses must have no demerit points in the current scoring cycle, or holders of other types of driver's licenses must have fewer than 12 demerit points in the current scoring cycle; Holders of large passenger vehicle, tractor, city bus, medium-sized passenger vehicle, or large truck driver's licenses who have demerit points in one scoring cycle, as well as holders of other types of driver's licenses who have been involved in a traffic accident resulting in death and assumed equal or greater responsibility without having their driver's license revoked, must have completed the inspection education; The applicant must have no pending road traffic safety violations or traffic accidents; The applicant's physical condition must meet the driving license requirements; The driver's license must not be under circumstances such as being seized, detained, temporarily suspended, revoked, canceled, or annulled by law.
