New from the straight line specialists at Pro-Line are the Reaction HP belted SC drag tires in a new compound, Ultra Blue. The super soft compound requires less break-in and conditioning than other compounds, extending tire life while also providing more traction throughout the life of the tread. Each tire is molded with a herringbone weave belt to eliminate tire growth and is supported by grey open cell foam inserts.
