The tread has a contact face intended to come into contact with ground during rolling and comprising at least one primary groove having depth D and being delimited by groove sidewalls. The groove sidewalls are axially connected by a groove bottom. The primary groove is provided with a closing device including at least two flexible fences. A first flexible fence has a thickness t1 extending from the groove bottom, and a second flexible fence has a thickness t2 extending from one of groove sidewalls toward the other. The flexible fences are distant each other in an orientation the primary groove extends with a gap g and overlap partly in sectional view of the primary groove. The gap g is at most equal to 1.0 mm. This tread provides further satisfactory reduction on groove resonance and productivity for manufacturing such tread.
