1. A seed press wheel for sowing units for precision seeders, comprising a solid tire in the shape of a disc that has a predetermined axis for mounting the solid tire on a hub, the hub having a protrusion and the solid tire including an untapered first portion extending radially from the axis and having a groove engaging the protrusion to constrain the solid tire on the hub, and a tapered second portion extending radially from the first portion, wherein the first portion is made of a first material having a first modulus of elasticity value, and the second portion is made of a second material having a second modulus of elasticity value, the first modulus of elasticity value being greater than the second modulus of elasticity value, wherein the second portion and the hub are connected only through the first portion, and wherein the second portion defines a tread of the solid tire.
