The present invention relates to a method of retreading a tire and a retread tire (10) made by this method. The method comprises the steps of providing a tread layer (40) having a tread side (44) and a sole side (46) wherein the surface of the sole side (46) includes a plurality of tread elements (48) such as sipes and/or grooves or other void. Each tread element (48) has a first edge (64) and a second edge (66) at the surface of the sole side (46) of the tread layer (40). At least one of the first edge (64) and second edge (66) is formed to have a break edge (84) such as a rounded edge or a chamfered edge of 0.4 mm or more. The break edge (84) removes the sharp corner and provides increased endurance for the retreaded tire (10).
