The invention relates to a
tread compound for a passenger tyre with high wet skid resistance and a preparation method thereof. The
tread compound comprises, by weight, 13 to 16 parts of
natural rubber, 61 to 83 parts of first solution-polymerized
styrene butadiene rubber, 25 to 40 parts of second solution-polymerized
styrene butadiene rubber, 10 to 20 parts of
carbon black, 45 to 55 parts of white
carbon black, 2 to 7 parts of a softener, 5 to 6 parts of an activator, 3 to 4 parts of an
antioxidant, 1.8 to 2.2 parts of a wet skid resistance reinforcing agent, 4.5 to 5.5 parts of resin with high wet skid resistance, 7 to 9 parts of a
coupling agent and 3 to 3.5 parts of a vulcanizing agent. The tyre prepared from the raw materials provided by the invention has wet skid resistance reaching grade A or above and is a high quality tyre with superhigh wet skid resistance.
