3 Answers
The difference between Dunlop LM705 and SP270 lies in their positioning. The Dunlop LM705 focuses on quietness, comfort, and high stability, while the SP270 emphasizes energy efficiency and environmental friendliness. Dunlop LM705: Good stability and handling, quiet, comfortable. Its tread incorporates various high-tech features, with tread rigidity enhanced from the inside out, effectively providing stability and handling. It also has certain noise reduction capabilities. Dunlop SP270: The Dunlop SP-SPORT-270 offers strong performance and complete comfort. It is a typical passenger car tire, specially enhanced with high-tech materials, featuring high-quality noise reduction performance. Its unique tread design provides drivers with a comfortable driving experience. These characteristics of the Dunlop SP-SPORT-270 allow the vehicle to better meet the needs of young consumers. The Dunlop SP270 tire is known for its low noise and elegant comfort, enhancing the perfect joy and experience of life.
I just changed my tires and have used these two models. The LM705 focuses on comfort and quietness, with road noise on highways so low it feels like driving a different car, and minimal vibration over speed bumps. The SP270 is more wear-resistant—I've driven 50,000 km and the tread is still deep, but the noise is noticeably louder, especially on concrete roads where it hums. In terms of wet traction, the LM705 performs better. During a heavy rainstorm on the highway, I had to brake hard and it stopped firmly, while the SP270 was slightly slippery on wet surfaces. Price-wise, the LM705 costs about 300-400 yuan more per tire, but the comfort and safety are worth it. For family sedans, I recommend the LM705; if you frequently drive on rough roads, go for the SP270.
When studying tire parameters, it was found that the LM705 uses an asymmetric tread pattern design to enhance wet performance, with a special groove structure that reduces the risk of hydroplaning. The SP270 features a simple, symmetrical tread pattern with lower rolling resistance, saving about 5% on fuel, but its handling is slightly inferior. In terms of rubber compound, the LM705 contains more silicon to improve low-temperature grip, providing better stability on icy roads below freezing. The wear resistance index for the LM705 is 420/TREADWEAR 500, while the SP270 is 600/TREADWEAR 620, meaning the latter has a lifespan approximately 20,000 kilometers longer. During high-speed cornering, the LM705 offers stronger lateral support, particularly noticeable in hairpin turns.
