The invention discloses an off-road tyre with low tyre noise. According to the design principle of a low-noise tyre, pitches of tyre patterns are optimized, and are enlarged or narrowed so as to form five kinds of different pattern pitches, and specific permutation and specific combination are performed, so that the purpose of reducing the tyre noise is achieved; besides, pattern blocks are arrayed on the tyre in a stagger manner in the width direction and arranged on the tyre in an interlocked manner, so that an excellent edge effect can be realized, and pattern noise is reduced; five kinds of the different pattern pitches, namely a first pattern pitch a, a second pattern pitch b, a third pattern pitch c, a fourth pattern pitch d and a fifth pattern pitch e, are arranged in the circumferential direction of the tyre, ,are in a relationship that a/b is greater than or equal to 0.91 and smaller than or equal to1.28, b/c is greater than or equal to 0.94 and smaller than or equal to1.37, c/d is greater than or equal to 0.93 and smaller than or equal to 1.43, and d/e is greater than or equal to 0.85 and smaller than or equal to1.37; tyre crown pattern blocks and tyre shoulder pattern blocks are arrayed on the tyre in the stagger manner in the width direction, and the tyre shoulder pattern blocks and the adjacent tyre crown pattern blocks are arranged in the interlocked manner.
