The Regal cannot continue driving with a tire pressure of 208 kPa. The standard tire pressure for the Regal is between 2.3-2.5 bar, and 208 kPa is below the normal tire pressure value. According to the international GBT2978-2008 standard, the recommended tire pressures are as follows: standard tires should be inflated to 2.4-2.5 bar; reinforced tires should be inflated to 2.8-2.9 bar; and the maximum pressure should not exceed 3.5 bar. The hazards of low tire pressure include: increased friction with the road surface, leading to higher fuel consumption; difficulty in steering and increased tendency for the car to veer, which compromises driving safety; excessive movement of tire components, causing abnormal heat generation due to over-compression; reduced functionality of the tire's cords and rubber, leading to delamination or cord breakage, as well as excessive friction between the tire and rim, resulting in damage to the bead area and abnormal wear.

After driving for so many years, I think 208kpa is indeed a bit low for tire pressure. The standard tire pressure for the Regal is usually between 230 and 250kpa. Driving with such low pressure can be nerve-wracking. If the tire wear increases or a blowout occurs, it's no small matter, especially on the highway. I suggest finding a service station to inflate the tires immediately. It might be okay for short distances at low speeds temporarily, but don't push it. Make it a habit to check the tire pressure monthly, as pressure naturally decreases when the car is left unused for a long time. Be extra cautious during the hot summer months, as low tire pressure combined with high temperatures can easily cause the tires to overheat and deform.

Based on my daily driving experience with the Buick Regal, maintaining 208kpa is acceptable for short distances, such as driving a few hundred meters to a nearby repair shop. However, driving too far will result in significantly increased fuel consumption—a long trip could cost you dozens of yuan extra in fuel. The inner side of the tires will also wear out more quickly, leading to higher replacement costs later. Carrying a portable air pump to top up the pressure yourself is a simple and cost-effective solution. Don’t just focus on the numbers; if the car feels unstable or the steering wheel becomes heavy while driving, that’s a clear signal to pull over. Developing a habit of regular checks can save you a lot of hassle.

Last time my tire pressure dropped to 210 kPa. On my way to work, I noticed the car was swaying and fuel consumption increased sharply. I immediately found a roadside stall to refill the tires, and the problem was solved. At 208 kPa, it's close to this level, and driving at low speed for a few minutes is not a big issue, provided you're on flat city roads and not the highway. However, be cautious when the weather gets colder as the tire pressure may drop even lower; parking overnight could reduce it by a few kPa. The Regal's tires are quite durable, but don't be careless. Regularly checking with a tire pressure gauge ensures peace of mind. Saving money and hassle is what matters most.
