Compared with the four-groove tire, the three-groove tire has one less groove. Therefore, the probability of breaking the rubber block with small stones is low, and it is more wear-resistant than the four-groove tire under the same conditions.
Compared with the three grooves, the four grooves have one more groove on the tire crown, and one groove less rubber, so the rolling resistance is lower and more fuel-efficient. Therefore, in a word, under the same conditions, (the same vehicle conditions, the same route, the same load, the same tire pressure, the same driver's driving habits, the same tire rubber, technology, and weight) "three grooves are more wear-resistant, and four grooves are more wear-resistant. The ditch is more fuel efficient.”
