This tube features the TR179A valve, a heavy-duty bent metal stem designed specifically for OTR and grader rims. The valve’s sturdy construction and precise angle allow for easy access in deep-dish rims while ensuring it remains protected from debris and mechanical damage during operation. The high elasticity and thickness of the Nexen compound ensure that the tube fills the tyre casing perfectly, reducing the risk of friction-related failures and extending the overall life of the tyre assembly.
