What are the differences between Chaoyang tires RP18 and RP26?

[VanMicah]

RP18 and RP26 differ mainly in terms of noise performance and wear resistance. 1. In terms of noise performance, RP18 is better than RP26. RP18 focuses on optimizing the tread design, effectively improving the tire's ability to absorb vibrations and reducing the impact of bumps on passengers. The Chaoyang RP18 tire pattern features continuous central ribs and non-intersecting lateral grooves, combined with variable pitch tread blocks. This multi-dimensional pattern optimization effectively disperses noise, creating a more comfortable driving environment. 2. Regarding wear resistance, RP26 outperforms RP18. The Chaoyang RP18 has a treadwear rating of 440, indicating average wear resistance. As the SA37 belongs to Chaoyang's mid-to-high-end tire products with significant improvements in comfort, the rubber compound tends to be softer, resulting in relatively lower wear resistance.
