What is the appropriate tire pressure for Baojun cars?

[DeLincoln]

The appropriate tire pressure for Baojun cars is 2.2-2.5 bar. Maintaining the correct tire pressure within the standard range is directly related to driving safety. Additionally, keeping the proper tire pressure significantly extends the lifespan of the tires. Hazards of over-inflation: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire life; increases vehicle vibration, indirectly affecting the lifespan of other components. Hazards of under-inflation: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive compression; weakens the function of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and ground, drastically raising tire temperature, softening the tire, and sharply reducing its strength. High-speed driving under these conditions may result in a blowout.

When I picked up my Baojun 730, the 4S dealership specifically emphasized the tire pressure values. They recommended maintaining around 2.5 bar for daily use, which is printed on the label inside the driver's door frame. Before driving on highways during hot summers, I reduce it to 2.3 bar to prevent thermal expansion, while in winter I adjust cold tires to 2.6 bar to compensate for heat loss. Once when fully loaded with 5 passengers and luggage on mountain roads, I had to increase to 2.7 bar to prevent sidewall collapse. The factory Kumho tires are quite stiff - 2.5 bar feels acceptable over speed bumps, but after switching to Continental CC6, 2.4 bar provides better comfort. Always remember to measure when tires are cold - pressure can be 0.3 bar higher right after highway driving.

Last time I helped my neighbor check the tire pressure warning light on his new Baojun RS-5, I found all four tires were only at 1.8 bar. The mechanic said this vehicle comes with TPMS, and the manufacturer's standard is 2.2 bar for front tires and 2.1 bar for rear tires when unloaded, increasing to 2.3 bar for both front and rear when fully loaded. An experienced tire shop technician shared a trick: observe the tread contact pattern - on regular roads, if 4 tread grooves are fully in contact the pressure is too low, while only 3 means it's overinflated. In our area where winter temperatures drop below zero, tire pressure requires special attention. My colleague's Baojun E300 suffered sidewall cracks last year due to insufficient pressure, costing over 800 yuan for tire replacement.

Three-year experience summary of driving Baojun 510: Maintaining 2.4bar tire pressure is most balanced for urban commuting. Once I drove with 2.0bar pressure for a month, fuel consumption surged from 6.2L to 7.8L, and the inner tire edges developed feathering wear. The repair shop used a nitrogen inflator to refill to 2.5bar, claiming nitrogen has better thermal stability than air. The redesigned 510PRO now uses wider 195 tires requiring reduced pressure to 2.3bar. Pay special attention to the spare tire - last year when I needed it, I found only 1.5bar pressure remaining. Now I check quarterly with a mechanical gauge as electronic monitoring modules sometimes have delayed alerts.

The tire pressure for Baojun models depends on the powertrain configuration. My hybrid version of the Kaijie has a factory setting of 2.6bar, which is 0.2bar higher than the fuel version. For models with independent rear suspension, it is recommended to maintain the same tire pressure for both front and rear tires. For models with torsion beam rear suspension, such as the 310W, the front tire pressure should be 0.1bar higher. Last week, while helping a car club friend check their kiWi EV, I found that microcars have thicker tire walls, requiring a tire pressure of 2.8bar for better support. The factory tire pressure monitoring system is prone to false alarms at temperatures below -10°C, so friends in Northeast China are advised to calibrate it before winter. If you're switching to wider tires, remember to recalculate the tire pressure—215-width tires should be inflated 0.1bar higher than the factory 205-width tires.
