下せしめる。(Prior Art) Since tires for construction vehicles run on harsh and uneven roads, the treads may be cut by sharp rocks, etc., or the rubber may be torn, which significantly shortens the life of the tires.
この為、従来はカットを防ぐ為にはトレッドゴムを硬く

It was being done. However, 1) When a styrene-butadiene polymer (for example, SBR #1500) is used as the polymer, the cut resistance improves, but the disadvantage is that the tire runs at high speed,
In the case of high operation, the tire case part breaks down due to heat accumulation, which significantly shortens the tire life.

10% by weight or more of the styrene-butadiene copolymer rubber has a styrene content of 25 to 35% by weight, and a vinyl bond content of the butadiene moiety. For 100 parts by weight of a rubber component which is a styrene-butadiene copolymer rubber with a high styrene content of 30% or less, the nitrogen adsorption specific surface area (NSA) is 110 to 170 m2/
40 g of carbon black with a dibutyl phthalate absorption (DBP) of 85 to 150 ml/100 g.

し、建設車輌用タイヤとして好ましくないためである。In the present invention, the above-mentioned high styrene content styrene-butadiene copolymer rubber (SBR) alone or the SB
When using a blended rubber of 50% by weight or more of R and other diene rubber, the SBR should be 50 to 100% by weight of the rubber component because if it is less than 50% by weight, the tire's cut resistance and rubber chipping resistance will be reduced. This is because the improvement effect cannot be achieved. In the present invention, other diene rubbers to be blended into the high styrene content SBR include natural rubber, synthetic polyisoprene rubber, and polybutadiene rubber. Also, the above SB
10% by weight or more of R has a styrene content of 25 to 35% by weight
Therefore, it is necessary that the vinyl binder content in the butadiene part be 30% or less, but this is because if the styrene content is less than 25% by weight, the effect of improving the tire cutability and rubber chipping resistance will not be achieved. In addition, if the styrene content exceeds 35% by weight or if the vinyl bond content in the butadiene portion exceeds 30%, the heat resistance of the tire decreases and the tire temperature decreases. This is because the tire rises, making it undesirable as a tire for construction vehicles.

00% by weight, there is no need to add a large amount of filler (N25A is 110 to 170 m"/g, preferably 130 to 170 m2/g, and DBP is 85 to 170 m"/g).

If P is less than 85 m1 / 100 g, the cut resistance and rubber chipping resistance of the tire will decrease, and N25A will be 17
If it exceeds 0m2/g and DIP is 150. d/
If it exceeds 100 g, heat resistance deteriorates, which is not preferable. If the amount of crab bone plaque is less than 40 parts by weight, the cut resistance and rubber chipping resistance will decrease, and if it exceeds 75 parts by weight, the heat resistance will decrease and the tire temperature will increase, which is undesirable.

By blending preferably 5 to 15 parts by weight, both cut resistance and appearance were achieved. If the dicyclopentadiene resin is less than 0.5 parts by weight, cut resistance and appearance will not be satisfied, while if more than 20 parts by weight is added, the cut resistance and rubber chipping resistance will not be improved any further. ,・It becomes less advantageous in terms of cost.
