A car's spare tire can be used normally on the road. Here is an introduction to car spare tires: 1. Introduction: It is a backup tire prepared for the car. Once a tire bursts or has a problem, the spare tire can replace it in time, preventing the car from breaking down midway. 2. Types: Full-size spare tire, non-full-size spare tire, and run-flat spare tire. 3. Usage: Specialized stores have strict requirements for the rotation of original tires, and spare tires are even less suitable for rotation. Tire rotation is a balance of wear on different parts, and cross-rotation is no longer recommended. Front-to-rear rotation also has issues with uneven wear. Since spare tires have different wear patterns, using them in rotation can increase safety risks.

That time I went on a road trip, I had a flat tire halfway and had to use the spare tire as an emergency solution. The spare tire works, but never think of driving on it long-term. It's usually a non-full-size design, smaller by one size, making the ride unstable with severe steering wheel shaking, especially terrifying on highways. Last time, I only drove 30 kilometers before finding a shop to fix the tire—remember not to exceed 80km/h, or you risk losing control or another blowout. Crucially, spare tire pressure is often overlooked; check it regularly to prevent leaks. In short, it's only for emergencies—switch back to a normal tire immediately after use. Safety first; don't cut corners for convenience.

A spare tire is not a universal solution, it's only a temporary fix. I've used it a few times - it barely works in the city, but becomes extremely dangerous on highways due to potential size differences, reduced traction, longer braking distances, and increased risk of skidding accidents. The risks multiply during rain or snow. After installing a spare, head to the nearest repair shop immediately (don't exceed 50km) and drive cautiously. Remember, spare tires can deteriorate too - check for rubber cracks or low pressure during routine maintenance, don't wait until emergency use. Safe driving is paramount - never gamble with lives.

When driving on a spare tire, it's like your temporary buddy, but don't rely on it for too long. Once I had to use a spare in an emergency, and it was noisy, bumpy, and I couldn't go over 80km/h. I also didn't dare to drive too far. Actually, spare tires come in full-size and compact sizes. If it's the same model, you can drive a bit more, but it's best not to exceed 100 kilometers; the compact ones must be replaced sooner. The key points are to stay focused while driving, avoid sharp turns or sudden braking, don't push for speed, and find a repair shop to replace the tire properly.
