Is it possible to drive a sedan on the 318 Sichuan-Tibet Highway?

[DelSabrina]

318 Sichuan-Tibet Highway can be driven by sedan. Here are some considerations for self-driving on the Sichuan-Tibet Highway: Chassis issues: Although the road conditions of the Sichuan-Tibet Highway have improved year by year, there are still many problems when driving during the rainy season. In high-altitude areas, cars with low displacement already have insufficient power. If encountering landslides or water-damaged roads, the low chassis of a sedan makes it difficult to pass. Some places may even cause the chassis to scrape. Tire issues: Although the road conditions of the Sichuan-Tibet Highway are getting better, with most sections being asphalt roads, there are still some sections that are gravel roads due to natural conditions and are constantly under repair. It is inevitable to encounter sharp stones scattered everywhere, cutting into the tires like knives. The tires of sedans, which are thinner and designed for asphalt roads, cannot withstand the significant damage caused by gravel roads. Additionally, the altitude changes along the Sichuan-Tibet Highway, ranging from over 4,000 meters to just over 2,000 meters, greatly affect the tire pressure of sedans typically used for urban roads.
