What is the suitable tire pressure for a Baojun 730 carrying 7 passengers?

[DeKyle]

The official recommended tire pressure for the Baojun 730 is approximately 2.3-2.5 bar, and it is more appropriate to adjust the tire pressure to 2.5 bar when carrying 7 passengers. According to the provisions and requirements of the international GBT2978-2008 standard, different tire pressures are divided into standard tires at 2.4-2.5 bar; reinforced tires at 2.8-2.9 bar; the maximum air pressure should not exceed 3.5 bar. In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. In summer, the tire pressure can generally be set at the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. The hazards of excessive tire pressure include reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating the wear of the central tread pattern, shortening the tire's lifespan, etc. The hazards of insufficient tire pressure include an increased friction coefficient between the car and the road surface, leading to higher fuel consumption; causing the steering wheel to feel heavy and prone to deviation, which are factors detrimental to driving safety; increasing the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire, etc.

I've been driving the Baojun 730 for several years, often carrying a full load of 7 people on long trips, so tire pressure is quite important. The standard tire pressure is usually indicated on the small label on the door frame or in the user manual, typically around 2.4 bar for the front tires and 2.4 bar for the rear tires. When fully loaded, I slightly adjust it to 2.5 bar measured when cold to avoid excessive tire flattening or rapid sidewall wear. Remember to use a tire pressure gauge for checking, and don't do it when the tires are hot, as the readings won't be accurate. By the way, incorrect tire pressure not only increases fuel consumption but also affects braking and cornering safety. I recommend checking it yourself every two weeks—it's low-cost but can prevent major issues. Safety comes first, ensuring peace of mind for family trips.

As a family car owner, I often take my Baojun 730 out with 7 people. The tire pressure should follow the recommended values in the manual, usually around 2.4 bar consistently. When fully loaded, there's no need to add too much pressure—keeping it as is can sufficiently support the weight. The key is to pay attention to changes in tire pressure. If it's too high, the ride becomes bumpy and uncomfortable; if it's too low, it increases the risk of a flat tire or higher fuel consumption. I make it a habit to get a free check at the repair shop at the beginning of each month. In fact, maintaining the correct tire pressure can extend the tire's lifespan, saving both money and hassle. Don't overlook these small details—it ensures the kids sit securely in the back.

Young car owners often ask how to adjust the tire pressure for this car. I drive a Baojun 730 with 7 people for daily commuting. Just check the user manual or the door frame, the standard is 2.4 bar. No need to adjust when fully loaded, the original value is fine. Remember to use a simple tire pressure gauge when the tires are cold to ensure they're within the recommended range. Proper tire pressure ensures smooth handling and reduces annoying tire noise. Regular checks can prevent accidents—simple yet practical.
