Carefully selected materials are used to meet performance requirements at different tyre levels depending on the use. Soft, supple carcasses quickly adapt to the shape of the ground when rolling and in curves. This increases ground contact and grip and improves shock absorption on poor road surfaces. Soft, natural rubber treads are combined with light, flexible puncture protection. Polyester is the cheapest of all handmade carcasses. It is a synthetic material that is very strong and waterproof and offers much more flexibility and durability than comparable nylon materials.

Challenge tires wear 10 - 20% faster than the competition, but they score with significantly improved performance and feel throughout their life. Depending on the requirements, the tyres are equipped with different soft rubber compounds. The SMARTplus compound is a somewhat harder natural rubber compound specially designed for high mileage. The formulation effectively reduces wear, making the tyre even more resistant and durable.\u003c\/p\u003e\n\u003ch4\u003eGanzo \u0026amp; PPS2\u003c\/h4\u003e\n\u003cp\u003eSome tyres designed for use on rough roads, cobblestones and gravel are equipped with PPS2 (Puncture Protection System 2).

The Ganzo Puncture Protection System is a highly flexible, even tighter woven multi-component puncture protection system, which is incorporated between the tread and carcass.
