What is the normal tire pressure for a BYD Song when cold?
3 Answers
The normal cold tire pressure for a BYD Song is between 2.4 and 2.5 bar. In winter, it is advisable to slightly increase the tire pressure by about 0.2 bar based on the standard tire pressure. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. The BYD Song is the dual-mode version of the BYD S3, positioned as a new energy compact SUV. In terms of body dimensions, the car measures 4565 mm in length, 1830 mm in width, and 1720 mm in height, with a wheelbase of 2660 mm. The front suspension type is MacPherson independent suspension, and the rear suspension type is multi-link independent suspension. It features a front-engine, front-wheel-drive layout with a unibody structure.
I remember since I started driving the BYD Song, the normal cold tire pressure has been between 230 to 250 kPa. Before each start, I would park the car overnight and then do a quick check with a tire pressure gauge. In summer when temperatures are high, tire pressure tends to rise, so I usually keep it at 230 kPa; in winter when it's colder, tire pressure drops quickly, so I top it up to around 240 kPa. Checking when the tires are cold is most important because after driving for a while, the tires heat up and the pressure increases, making the reading inaccurate. Once I forgot to check, and the tire pressure was a bit low—the car felt unstable and consumed more fuel. Both the car manual and the door sticker have recommended values; just follow them. For an SUV like the BYD Song, which has a heavy body, incorrect tire pressure has a significant impact: too low and it accelerates tire wear and increases fuel consumption; too high and braking becomes harder to control. I recommend checking regularly—it’s a habit that saves worry and keeps you safe.
Safety is something that cannot be overlooked. The recommended cold tire pressure range for the BYD Song is 230 to 250 kPa. I always emphasize checking the tire pressure when the car is cold, meaning the vehicle has been parked for several hours and the tire temperature has stabilized. If the tire pressure is too low, the tires are prone to deformation, increasing the risk during high-speed cornering. Conversely, if the pressure is too high, traction decreases, making the car more likely to skid in rainy conditions. I personally use a portable tire pressure gauge, which has minimal measurement error. Seasonal changes have a significant impact: in winter, cold temperatures can naturally reduce tire pressure by 10-20%, so I regularly top up the air. In summer, avoid overinflating to prevent overheating issues. The recommended values can be found on the inside of the door—just check there. A small adjustment in tire pressure can prevent blowouts, proving that road safety starts with attention to detail.
