How to Reference the Tire Load Index?

According to the tire reference table, for example, in the tire specification 195/65R-1591V, the load index is 91, which corresponds to a maximum load capacity of 615 kg, and the speed rating is V, meaning the maximum speed is limited to 240 km/h. Related information is as follows: 1. Tire Pressure: Tire pressure should not be too high or too low. You can use a small tire pressure gauge to measure the pressure, generally checking once a month. Compare and adjust according to the vehicle's own optimal standard tire pressure. For larger vehicles such as SUVs and commercial vehicles, the tire pressure is usually between 2.5—3 bar, while for ordinary models, it is generally between 2.2—2.5 bar. 2. Balance: Check the tread and sidewall for cracks and regularly correct the wheel balance. 3. Bulging: If you notice any bulging on the tire or experience abnormal vibrations and noises while driving, promptly determine if it is a sign of a potential tire blowout.

Must the Original Owner Be Present for Vehicle Transfer?

Vehicle transfer can proceed without the original owner's presence, but the following documents are required: The original owner needs to provide the vehicle registration certificate, driving license, and ID card. The buyer needs to provide an ID card, and if they are from another region, a residence permit or temporary residence certificate is also required. The original owner's commercial insurance can be canceled (compulsory insurance cannot be canceled), or it can be transferred to the buyer at the insurance company. Points to note when purchasing a used car: Incomplete documentation. Complete documentation for a used car includes: the vehicle registration certificate (or original purchase invoice), driving license, vehicle purchase tax payment certificate, road maintenance fee records, and compulsory insurance. Missing documents like the vehicle registration certificate or driving license, or unpaid compulsory insurance or road maintenance fees, can cause endless trouble for the buyer. Therefore, if the seller cannot provide complete documentation, buyers should be especially cautious. Odometer tampering. Many buyers rely on the odometer to judge a car's condition, and sellers often take advantage of this by tampering with the odometer. The odometer is not just an indicator of usage intensity but also a record for the maintenance and replacement of other vehicle components. If buyers follow the maintenance schedule based on a tampered odometer, it can lead to a series of potential safety hazards. New paint covering damage. When buying a used car, if the car has been repainted and there are signs of repair around the front, rear, or A, B, and C pillars, the car may have been involved in a major accident. Engine tuning to raise the price. Many buyers focus too much on the car's engine and neglect the overall condition of the body. Used car sellers exploit this by replacing engine components to make the engine appear younger, thereby inflating the price.

How many kilometers should the spark plugs of Corolla Hybrid be replaced?

Corolla Hybrid spark plugs should be replaced every 100,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. Judge the condition of the spark plugs based on the following appearance colors. Normal spark plugs have a skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm, and no signs of electrode burning. If the spark plugs are oily or have deposits, but the spark plugs themselves are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected for the spark plugs or that the air-fuel mixture is too rich, with oil creeping up.

Can I add PetroChina oil after adding Sinopec oil?

You can switch to PetroChina oil after using Sinopec oil, as long as the gasoline meets national standards. Below are specific comparisons between PetroChina and Sinopec: 1. Raw materials: Although PetroChina and Sinopec use almost the same processes, their additives differ. Sinopec uses some of the best imported additives available globally. 2. Density: In terms of oil density, PetroChina's gasoline density is generally around 0.72–0.73, while Sinopec's oil density is around 0.75–0.77. The quality of both oils is similar, but PetroChina's oil density is slightly lower than Sinopec's. 3. Mileage: Since PetroChina's density is lower than Sinopec's, Sinopec's fuel tends to be more durable and powerful, and it is usually slightly more expensive. However, due to differences in crude oil sources, gasoline processing methods, procedures, and additive usage between the two brands, frequent mixing may lead to minor engine issues such as slight shaking and carbon buildup.

Does the Haval F7 spare tire have a tire pressure sensor?

Haval F7 spare tire has a tire pressure sensor. The following are the location and specific judgment of the Haval F7 spare tire pressure sensor: Location of the Haval F7 spare tire pressure sensor: The tire pressure of the Haval F7 is displayed on the dashboard, which can monitor tire pressure and temperature in real time. When the tire is abnormal, it will alarm to remind the driver to take corresponding measures to avoid accidents. Taking the 2021 Haval F7 as an example, it is a compact SUV with a body size of 4620mm in length, 1846mm in width, 1690mm in height, a wheelbase of 2725mm, and a minimum ground clearance of 169mm. The 2021 Haval F7 is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 169PS, a maximum torque of 285Nm, a maximum power of 124kW, and is matched with a 7-speed dual-clutch transmission. Specific judgment: Specific operation to check the tire pressure of the Haval F7: Press and hold the OK button on the steering wheel for five seconds, then use the up and down adjustment buttons to adjust to the tire pressure display interface, where you can view the pressure and temperature information of the four tires in real time. The tire pressure display function of the Haval F7 can intuitively show the tire pressure: too low or too high tire pressure is not good, and it will also trigger the tire pressure display or tire pressure alarm system. Insufficient tire inflation pressure will also lead to excessive tire wear, poor vehicle control, reduced fuel economy, and may also cause wheel deformation, so the tire inflation pressure should be kept within the specified value. The hazards of excessive tire inflation pressure: Excessive tire inflation pressure will lead to uncomfortable riding, excessive wear in the center of the tire tread, and increase the possibility of tire damage on dangerous roads.

What is the coverage and compensation amount of car insurance?

Coverage: The insured vehicle collides or overturns during use (Collision refers to direct contact between the insured vehicle and external objects, but human-induced scratches on the insured vehicle are not covered under the vehicle damage insurance; Overturning means the insured vehicle flips over due to natural disasters or accidents, losing its normal state and driving capability, and cannot be restored to driving condition without rescue.); The insured vehicle encounters fire, explosion, etc.; External objects collapse, airborne objects fall, or the insured vehicle falls parallel while driving; The insured vehicle is struck by lightning, storms, tornadoes, heavy rain, floods, tsunamis, ground collapse, ice collapse, cliff collapse, avalanches, hail disasters, mudslides, landslides, etc.; Natural disasters encountered by the insured vehicle during transportation (Only during transportation, with the 58 Auto driver accompanying and taking care of the vehicle, will the insurance company compensate); Compensation amount: Determined based on the extent of vehicle damage, with no uniform standard for compensation amount. Generally, there are the following scenarios: In case of total loss of the vehicle, compensation is calculated within the insured amount. If the insured amount exceeds the actual value of the insured vehicle at the time of the insurance incident, compensation is calculated based on the actual value of the insured vehicle at the time of the incident; In case of partial loss of the vehicle, for vehicles with the insured amount determined by the new car purchase price, compensation is calculated based on actual repair and necessary, reasonable rescue costs, using the formula: Actual repair and rescue costs - residual value. For vehicles with an insured amount lower than the new car purchase price at the time of insurance, in case of partial loss, compensation for repair and rescue costs is calculated based on the ratio of the insured amount to the new car purchase price at the time of the incident, using the formula: (Actual repair and rescue costs - residual value) × (Insured amount ÷ New car purchase price).
