My BYD Song PLUS DMi came with 215/55 R18 tires when I bought it, which provide a comfortable ride and good fuel efficiency. Remember that 215 refers to the tire width in millimeters, 55 is the aspect ratio, and R18 indicates 18-inch rims. It's stable for daily city commuting, and the replacement cost is reasonable. The 4S store recommends Michelin or Giti as the most suitable original tires for this model. Before changing tires, it's best to check the tire pressure and wear to avoid affecting handling and prevent accidents on long trips. BYD vehicles often follow this pattern—higher trim models might use larger 235/50 R19 tires, so it's advisable to confirm the tire specifications before delivery to avoid being misled. Over time, you can also compare how different tire brands affect fuel consumption and noise levels.
I work in auto repair and once helped a friend check the tire specs for the BYD Song PLUS DM-i. It comes standard with 215/55 R18 or optionally with 235/50 R19 tires. Those numbers in the tire size are crucial—for example, 215 indicates the width in millimeters, and 55 is the aspect ratio, which affects grip and cornering stability. The tires used on the Song PLUS DM-i are fuel-efficient and quiet for regular road conditions, but you should upgrade to winter tires for snow and ice. During maintenance, you can scan the QR code with an app to check the OEM specs—don’t swap them randomly. Different brands like Continental or Goodyear offer similar sizes but at double the price difference. Always match the rim size correctly to avoid affecting the ABS system, and regularly measure tread depth with a caliper to extend tire life.
I've been driving the Song PLUS DMi for almost two years with standard 215/55 R18 tires, which are fine for daily commuting. After long-term use, it's important to check tire pressure as too high or too low can affect fuel consumption. The model number is clearly labeled on the door sticker, and it's recommended to replace them regularly. To save money, you can opt for aftermarket brands as long as the size remains unchanged—don't make random modifications. Changing tires costs just a few hundred yuan.
