The invention discloses a special sand tire and
wear resistance detection device thereof. The special sand tire comprises a tire body, wherein a tire
tread is formed on an outer ring of the tire body,a tire shoulder is formed on an edge of the tire
tread, a plurality of pattern blocks are arranged on the tire
tread and the tire shoulder, and the pattern blocks are symmetrically arranged on the left side and the right side of the circumferential axis of the tire tread in a staggered mode; each pattern block comprises a tread pattern
block group arranged on the tread and distributed along the circumferential direction of the tire, and a tire shoulder pattern
block group arranged on the tire shoulder and distributed along the circumferential direction of the tire, and the
tail end of the tire shoulder pattern
block group extends towards the tire side to form an under-shoulder pattern block. According to the special sand tire, a computer model is established to simulate the size and shapeof a grounding mark, the grounding pressure and distribution condition, and the
contact condition of a pattern and a soft pavement of a tire in soft lands such as deserts, sand lands, beaches and thelike so as to design a pattern groove with a U-shaped structure and an undirected blocky pattern block; the passing rate of the special sand tire on a soft
road surface is increased, the functions ofwater drainage, mud
discharge, sand
discharge and the like are improved, stability and the quick turning performance of a vehicle are improved, and meanwhile the control performance of the tire is improved.
