The invention provides an all-road-condition tire. A circumferential main groove is sequentially divided into a first circumferential main groove body, a second circumferential main groove body, a third circumferential main groove body and a fourth circumferential main groove body in the tire width direction; according to crown pattern blocks, a plurality of first crown pattern block bodies are defined through the first circumferential main groove body and the second circumferential main groove body, a plurality of second crown pattern block bodies are defined through the second circumferential main groove body and the third circumferential main groove body, and a plurality of third crown pattern block bodies are defined through the third circumferential main groove body and the fourth circumferential main groove body; and the second crown pattern block bodies are zigzag, and the adjacent second crown pattern block bodies are connected through strengthening ribs. The middle crown pattern block bodies of a crown are designed to be zigzag, the strengthening ribs are additionally arranged between adjacent block bodies, and therefore the main aims of improving the rigidity of the middle crown pattern block bodies and improving the linear walking stability are achieved; and the contact faces between the tire and snowfields and between the tire and mud fields can be increased, the interlocking manner is formed, and the tire can provide sufficient road holding force on the snowfields and the mud fields.
