摘要： A tire 2 includes a reinforcing layer 20 located between a tread 4 and a carcass 12. The reinforcing layer 20 includes a band 38 and a belt 40. The band 38 includes a full band 42 and a pair of edge bands 44. The full band 42 has an end 42e located axially outward of a shoulder circumferential groove 28s. The belt 40 includes a third belt ply 46C located radially inward of the pair of edge bands 44. A distance Y between each edge band 44 and the full band 42 or the third belt ply 46C is not less than 2.2 mm and not greater than 4.0 mm. A ratio of a tire thickness E at an end PE of a tread surface 22 to a tire thickness D at an equator plane is not less than 1.2 and not greater than 2.0.

摘要： Agricultural vehicle tire having tread (1) with bearing surface (10) on which main lugs (3) and shorter secondary lugs (3) are formed on each side of the equatorial mid-plane (XX′), each secondary lug (3) interposed between two main lugs (2). The main lugs (2) and secondary lugs (3) make up, in the radial direction, a lens (21, 31) of a first material, each lens (21, 31) surmounted by a second material extending to the contact face of the main lugs and the secondary lugs. The viscous modulus G′1 of the first material is at most 60% of the viscous modulus G′2 of the second material. The complex modulus G′1 of the first material differs from the complex modulus G′2 of the second material, the difference between these complex moduli being at most 30% of the complex modulus G′2 of the second material.
