This is pro-line's tire glue. Pro-line knows tires and understands that the strongest bond possible between the tire and wheel is a critical aspect of performance and tire longevity. Pro-line engineers have developed the best tire gluing system ever devised with the specific needs of RC users in mind – pro-line tire glue. The first challenge was developing the strongest glue possible while also having the correct flow characteristics and dry time that RC racers and bashers desire. Pro-line's new tire glue has a hold strength of 3,200 psi (test method: steel on steel in tensile shear) which is the highest strength of any tire glue available. Pro-line's unique glue formula also provides the fastest drying glue possible while drying crystal clear with no yellowing or whitening found when gluing tires with other glues. The pro-line development team did not just stop with improving the glue. Pro-line engineers began the design process with the clear goal of revolutionizing the glue delivery system (bottle and applicator tip).
