The spare tire of BYD Tang is placed under the car. You can see it by looking down at the chassis at the rear of the car. It is installed under the chassis. Before using the spare tire, you should use a tire pressure gauge to adjust the tire pressure. Precautions for using the spare tire: 1. Automotive beauty experts say that tires are rubber products, and if stored for too long, they will age. Generally, the aging period of tires is about 4 years, so the spare tire should be replaced after 4 years. 2. Spare tire inspection mainly involves checking tire pressure, wear, and cracks. Tires should be replaced as soon as possible before the tread wears to the wear indicator line. If there are small cracks on the sidewall of the tire, it should not be used for long-distance or high-speed driving because the sidewall of the tire is relatively thin, and high-speed driving can easily cause a blowout. 3. The spare tire should not be used for a long time. The spare tire is actually for emergency use, not for long-term use.

During the years I drove the BYD Tang, the spare tire was typically mounted underneath the rear of the vehicle's chassis, near the rear bumper. To access it, I had to first use the car's built-in jack to lift the vehicle at the designated points to ensure secure support. Then, locate the bolts on the spare tire mounting bracket, loosen them with the wrench from the trunk's tool kit, and slowly lower the spare tire. This process requires attention to tire balance to avoid sudden drops. I once had to change a flat tire during a road trip using this method and found the positioning quite convenient, though it's crucial to operate on level ground to prevent accidents. It's advisable to regularly check the spare tire's pressure—every six months—and maintain it at the standard value to ensure it's ready when needed. Additionally, since the spare tire is exposed to the elements, it can corrode over time; using a cover or regular cleaning can help extend its lifespan.

From the perspective of automotive space optimization, placing the spare tire under the rear suspension of the BYD Tang is a reasonable choice. I've considered that this approach frees up more trunk space, making daily cargo loading more flexible, while also lowering the overall center of gravity to improve driving stability. To access the spare tire, you first need to open the tool compartment under the trunk floor, retrieve the jack and specialized wrench, lift the vehicle, and then release the mounting bracket fasteners. Don't forget to ensure the ground is level and the vehicle is stationary—safety first. I've encountered users who mistakenly thought the spare tire was embedded within the chassis; in reality, it's externally mounted, making it prone to dust and rain accumulation. It's recommended to check the tightness of the screws and tread wear every season. This design is common among SUVs, with similar layouts seen in other brands. With proper maintenance, it can last five to six years without issues.

When I first got my BYD Tang, I was also curious about the spare tire location. Lifting the rear cargo floor revealed a recess for the toolkit, but the spare wasn't there - it's actually mounted underneath the rear chassis. The replacement process is straightforward: park and engage the handbrake, use the jack to lift the rear wheel side, then loosen the mounting bracket bolts to remove the spare. Be careful not to jack at the wrong position to avoid damaging the frame. I've used it once - the process went smoothly though the spare is smaller than the original tire, so drive slowly for temporary use. Regularly check tire pressure, ideally monthly, to avoid unnecessary hassle with flats. The space-saving design is clever, but watch out for road debris hitting it.
