You can take the old tires with you after replacing car tires. If the replaced old tires are not severely worn, they can still be used as full-size spare tires. Uses of old tires: Tire Retreading: Tire retreading technology involves refurbishing and processing tires that have been worn or damaged due to other reasons, restoring them to usable condition. Oil Extraction from Waste Tires: The technology for extracting oil from waste tires involves heating, pressurizing, and adding catalysts to refine fuel from discarded tires. If simple and inexpensive equipment is used for this technology, it can easily cause secondary pollution. There are many hidden illegal workshops in remote mountains in China that engage in this practice, and there have been numerous reports about them in recent years. Rubber Powder from Tires for Waterproofing and Leak Repair: Waterproof membranes are mainly used for building leak repairs. Nowadays, most buildings undergo waterproofing and leak prevention work, and this industry is widespread across the country. The demand for waterproof membranes is enormous, and rubber powder is also a primary raw material for this technology, as waterproof membranes are a type of modified asphalt.

I remember when I got new tires last year, the mechanic at the shop reminded me not to just throw away the old tires. If the tread is still deep and there are no cracks, they can be used as a spare tire. I kept one in my car's trunk for emergencies, but over time, it may age and become brittle, so it's important to check it regularly for safety. Most of the time, recycling is the easiest option. Many repair shops or eco-friendly recycling centers accept old tires for free, where they can be shredded into granules for use in playgrounds or running tracks, which is both environmentally friendly and resource-saving. Don't leave them by the roadside to pollute the soil and water—they decompose slowly and can be hazardous. I've also seen people DIY them into flower pots or toys, but make sure the tire is in good condition and securely placed to avoid accidents that could harm children. In short, recycling should be the first choice—it's a habit that can also help lighten the Earth's burden.

Why is the cold air from a diesel car's air conditioner not cold?

The reasons why the cold air from a diesel car's air conditioner is not cold are as follows: 1. Too much refrigerant: This leads to a decrease in cooling efficiency. 2. Too little refrigerant: Insufficient refrigerant causes the condenser to become dirty, and a loose compressor drive belt can also result in the air conditioner not cooling properly. 3. Excessive impurities: If there are too many impurities in the refrigerant and the refrigeration oil, minor blockages can occur, leading to insufficient cooling capacity. If there is excessive dirt in the refrigerant and refrigeration oil throughout the entire air conditioning system, it will inevitably clog the filter screen of the filter, reducing the cooling passage capacity and increasing resistance. This also means less refrigerant flows to the expansion valve, resulting in insufficient cooling capacity.

In Subject 4, does the left yield to the right or the right yield to the left?

Right-turning vehicles yield to left-turning vehicles. Below are some rules regarding vehicle yielding: 1. When both vehicles are going straight, yield to the right: At an intersection where both vehicles intend to proceed straight without traffic signals, simultaneous straight movement is highly dangerous. Thus, the 'yield to the right' principle is established, requiring the vehicle to yield to the right-side vehicle going straight. This rule applies not only at intersections but also when vehicles from both sides merge into the same lane, where the right-side vehicle should be allowed to change lanes first. 2. Right-turning vehicles yield to straight-going vehicles: To ensure traffic efficiency, right-turning vehicles must yield to straight-going vehicles. At intersections without traffic signals, both left-turning and right-turning vehicles must yield to straight-going vehicles.

What Causes Water Leakage Under the Co-Driver Seat in a Car?

Water leakage under the co-driver seat in a car is likely caused by a door leak. Below are related explanations regarding water leakage under the co-driver seat: Solutions: If you hear obvious water sloshing sounds when opening/closing the door or while driving, it indicates water accumulation inside the door. In this case, simply use a thin wire or small screwdriver to unclog the drainage holes—this can be easily done yourself. Detailed scenarios of leakage: If the window regulator has been replaced, it may be due to improper adhesion of the door waterproof membrane after the replacement, as the membrane needs to be peeled off during the regulator replacement process. If the waterproof membrane is not properly sealed, heavy rain can cause water to enter the cabin. You can either reseal it yourself or replace the waterproof membrane.
