The GRAVINE was developed to push the limits of a gravel tire even further: Excellent for rough terrain, it opens up completely new paths and adventures!
Its raised, open-profile lugs ensure better grip on muddy surfaces - efficiently evacuating mud and dirt for better self-cleaning. Combined with the excellent lateral support for increased cornering control and an optimized tread for easy rolling behavior, the result is reliable, high-performance driving behavior at all times.
Features:
Pro Handmade Tubeless Ready with Superpoly casing
Handcrafted tires combine a variety of outstanding features to provide maximum comfort and lowest rolling resistance. Carefully selected materials are used in different tire levels depending on usage performance requirements. Soft, supple carcasses quickly adapt to the shape of the surface when rolling and cornering. This increases ground contact and grip and improves shock absorption on poor roads. Soft, natural rubber profiles are combined with lightweight, flexible puncture protection.
Polyester is the cheapest of all hand-made casings. It is a synthetic fabric that is very strong and waterproof and offers significantly more flexibility and durability than comparable nylon materials. Challenge uses high quality polyester or SuperPoly (higher TPI polyester) to produce cost-effective Pro Level tires.
Perfect for use with tubeless systems: no tube, strong puncture protection and high efficiency.
Challenge's handcrafted natural rubber treads are compounded to provide the perfect level of durability without compromising performance, comfort and control. Although Challenge tires wear 10 - 20% faster than the competition, they offer significantly improved performance and a noticeably better driving experience throughout their lifespan. Depending on the requirements, the tires are equipped with rubber compounds of different softness.
The SMARTplus Compound is a slightly harder natural rubber mixture specially designed for high mileage. The formulation effectively reduces wear and makes the tire even more resistant and durable.
Puncture Protection System (PPS)
The PPS (Puncture Protection System) puncture protection system consists of one or more layers of fabric between the tread and the tire carcass. PPS significantly increases the tire's resistance to punctures and therefore offers maximum reliability.
Corazza Armor
Corazza Armor Silver: The first step with the gravel tires was to improve the side protection. The carcass is extended around the bead to the tread. This ensures longer durability and additional protection for the most stressed parts of the tire. In addition, the flexibility of the tire center is excellently complemented by the reinforced sidewalls - and in addition to improved puncture protection, it offers a smooth, soft ride.
Protective strips
The Gravine is equipped with a protective strip that increases the longevity of the tire by reducing the effects of scuffing or rubbing against the rim. In addition, it serves as a precise control option for ensuring that the tire sits evenly on the rim.
