What is the normal tire pressure for the 2021 Emgrand?
2 Answers
The normal tire pressure for the 2021 Emgrand is between 2.4-2.5 bar. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear of the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreased puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to blowouts; Increases tire deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, fatigues the cord layers, and breaks cords. It also increases the tire's contact area, accelerating shoulder wear.
I drive a 2021 Emgrand, and keeping tire pressure between 2.3 to 2.5 bar is the most reliable. The official recommended values are on the sticker on the door frame—adjust according to the label on the driver's side door when unloaded; it's clearly marked. When driving on highways in summer, tire temperature rises, so make sure the pressure doesn’t exceed 2.8 bar, or it’ll be too bumpy and risk a blowout. Remember, the spare tire pressure should be higher—around 3.0 for safety. Checking tire pressure twice a month with a mechanical gauge is the most reassuring, especially during seasonal changes with large temperature swings. If the warning light suddenly comes on, slow down immediately, pull over, and check the pressure—nails puncturing tires are common, so don’t push your luck.
