• a tread having a circumferential direction, an axial direction, and a radial direction,
• the tread having at least one circumferential groove which extends in the circumferential direction,
• the at least one circumferential groove having a groove base, and at least one groove sidewall;
• a plurality of traction elements in the circumferential groove connected to the at least one groove sidewall and the groove base;
• wherein at least one of the traction elements has at least one indentation formed on a radially outermost edge between the base portion and the at least one sidewall portion;
• wherein the radially outermost edge has a length L;
• wherein the at least one indentation has a length Li that is between about 0.2 and about 0.8 times the length L;
• and
• wherein the radially outermost edge has an angle of inclination θ relative to the radial direction.

• a tread having a circumferential direction, an axial direction, and a radial direction,
• the tread having two axially outer shoulder portions,
• at least one of the shoulder portions having a shoulder sidewall which extends at least partially in the radial direction;
• a plurality of traction elements on at least one of the shoulder portions, wherein the traction elements are connected to the shoulder sidewall;
