What is the general tire pressure?

Tire pressure is generally inflated to 2.4 to 2.5 bar, while reinforced tires should be inflated to 2.8 to 2.9 bar, with the maximum pressure not exceeding 3.5 bar. Tire pressure is an indicator of a vehicle's load capacity, as the load capacity depends on the level of tire pressure. When a car is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance, and tire pressure significantly affects the rolling resistance coefficient. Appropriately reducing tire pressure can improve ride comfort, but if the tire pressure is too low, it may affect other vehicle performance. Tire pressure is a crucial factor influencing tire lifespan and fuel economy, so it is essential to choose the appropriate tire pressure to extend tire life and enhance economic efficiency.

How thick are car tires generally?

Generally, the tread thickness of car tires is about 13mm, specifically consisting of 7mm tread pattern depth and 6mm tread thickness. Car tires usually adhere to technical standards, except for all-rubber tubeless tires. Typically, sharp objects exceeding 0.8cm can easily puncture car tires; for small trucks, sharp objects over 1.5cm are prone to damage tires; while for large trucks and buses, sharp objects around 2.5cm can puncture tires. Car tires are one of the crucial components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness, as well as maintaining excellent adhesion between the wheels and the road surface.

How Many Years Can Regular Tires Generally Be Stored?

Regular tires can generally be stored for 3 to 5 years. If they exceed 5 years, they should no longer be used, regardless of whether they have been used or not. The specific duration for which tires can be stored largely depends on the storage environment. Tires should always be stored in a cool, dry, and dark indoor area to prevent moisture accumulation inside the tires, which can be dangerous. When storing tires for extended periods, the following precautions should be taken: 1. Tires should be protected from direct sunlight and rain, and excessive ventilation should be avoided; 2. The storage location should be away from heat sources, electrical equipment, and areas that can generate ozone to prevent accelerated oxidation of the tires; 3. Tires should not be stored near flammable materials, oils, acids, alkalis, or other chemicals; 4. Tires stored for long periods should be rotated periodically to change their support points and prevent deformation.

How to Deal with Tire Pressure Loss?

Tire pressure loss refers to the situation where the tire pressure is insufficient and needs to be inflated. If you have a car air pump, you can inflate the tire a little and then go to a nearby repair shop for further inspection. If the tire pressure is too low to drive, you can pull over and replace the flat tire with a spare tire, then continue driving and get the tire repaired or replaced later. If the tire pressure monitoring system warning light comes on while driving, stay calm, avoid panic, immediately reduce speed, avoid sharp steering and sudden braking, and check the tires promptly. Insufficient tire pressure can lead to increased fuel consumption, uneven tire wear concentrated on both sides, and in severe cases, cause standing wave phenomena, directly increasing the risk of a tire blowout.

How to Fold Down the Rear Seats in a GL8?

The method to fold down the rear seats in a GL8 is: Pull the rings located at the lower left and right sides of the rear seats by hand to release and fold them down. The GL8 is an MPV model under the Buick brand, featuring a buckle-type fixed switch at the top of the rear seats. The seatbacks and cushions are connected by pivots, allowing the seatbacks to be easily folded down with a single touch. The proportional folding function enables segmented adjustment of the rear seatbacks, meeting the needs for increased trunk storage space and rear passenger accommodation. The GL8 incorporates design elements such as a three-dimensional waterfall grille, multi-dimensional blue Bi-Xenon HID headlights, a 360-degree wraparound interior design, and ice-blue ambient lighting, inheriting Buick's family design language. In terms of powertrain, the GL8 is equipped with a 3.0L V6 SIDI intelligent direct injection engine, a 2.4L Ecotec engine, and a six-speed automatic transmission. It also features OnStar all-time online assistant and QuietTuning noise reduction technology.

What to Do When Car Door Makes Noise When Opening and Closing?

When the car door makes noise during opening and closing, you can apply some grease to the door hinges to eliminate the noise. Many parts of a car are equipped with hinges, such as the engine hood, doors, and trunk lid. If the hinges are not maintained and lubricated in time, they may rust, increasing friction and causing noise when opening or closing the doors or engine hood. It is recommended to perform regular maintenance during daily car use, as routine maintenance is very important for the vehicle. Car maintenance mainly includes two items: replacing fluids and replacing wear parts. Fluids include engine oil, transmission fluid, coolant, brake fluid, and power steering fluid. Wear parts include belts, spark plugs, tires, brake pads, brake discs, fuel filters, air filters, cabin air filters, oil filters, and batteries.
