[0004] Although the above-mentioned prior art solution can achieve the effect of stable travel of the tire on land and use as an impeller when traveling in water by providing a strip-shaped groove, a circular arc surface and a second inclined surface on the crown, the crown is only provided on the outer side of the tread, and the sidewall cannot achieve the energy supply effect, thereby providing poor travel ability for the tire.

[0005] In view of this, we propose an amphibious tire. CONTENT OF THE UTILITY MODEL

[0018] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0019] The present application effectively solves the problem of poor driving ability of the tire by arranging the tire side on both sides of the tire tread and extending both ends of the tire crown to the outside of the tire side, increasing the contact area of the tire crown with water when acting as an impeller, and enabling the tire crown to provide more energy when rotating at a certain speed in water, thereby improving the driving ability and stability of the tire in water.

[0020] The present application increases the width and height of the tire cross section by forming the tire side from a circular arc segment A and a circular arc segment B, thereby forming a more stable buoyancy in the waterway and ensuring the stability of the tire driving in the waterway.

[0021] The present application sets the tire crown outside the tire tread to ensure stable grip when the tire drives on land, and sets the steel wire layer inside the tire tread and the tire side, so that the tire tread and the tire side in the tire can maintain a certain strength when driving on the road, thereby achieving the effect of water and land use.
