The invention discloses high modulus low shrinkage polyester curtain cloth, method and tyre used for manufacturing tyres, and belongs to the technical field of tire machining. The technical problems that the high modulus low shrinkage polyester curtain cloth is applied to agricultural tyres, motorcycle tyres or electric car tyres, and how the elongation is matched with the high modulus low shrinkage polyester curtain cloth are solved. According to the technical scheme, 1, the high modulus low shrinkage polyester curtain cloth is used for manufacturing the tyres, the high modulus low shrinkage polyester curtain cloth is applied to manufacture the agricultural tyres, the motorcycle tyres or the electric car tyres; 2, the method for manufacturing tyres by using the high modulus low shrinkage polyester curtain cloth is the method for manufacturing the agricultural tyres, the motorcycle tyres or the electric car tyres by using the high modulus low shrinkage polyester curtain cloth, and the cutting angle of the high modulus low shrinkage polyester curtain cloth differs by 0.2-6 degrees from the cutting angle of the standard curtain cloth; and 3, the high modulus low shrinkage polyester curtain cloth tyre is used for manufacturing the agricultural tyres, the motorcycle tyres or the electric car tyres, and the cutting angle of the high modulus low shrinkage polyester curtain cloth differs by 0.2-6 degrees from the cutting angle of the standard curtain cloth.
