German brand MC5 tires are said to have strong grip, but aren't all tires made of rubber? How can the grip be different?

the rubber used as a tire is not just pure rubber! In fact, a lot of additives are thrown into the rubber! For example, why is rubber black? This is because carbon black is added! After carbon black is mixed into rubber, it can effectively improve the hardness, wear resistance, strength and other indicators of rubber, making the tire wear-resistant, durable and strong, but adding too much carbon black will also reduce the friction coefficient of rubber, which makes it easy to slip on the road. However, in order to increase the friction coefficient with the ground, some tires specially add silicon material (white carbon black). However, improper addition will also cause problems such as insufficient strength of tires. Therefore, the tire formula itself is the secret of the enterprise, the same specifications, even the same pattern modeling, because the rubber formula is different, the grip may be completely different, not to mention different tire patterns are not the same! Mapai MC5 is a classic product that balances grip and quietness. Soft active silicon tread rubber formula, typical asymmetric pattern and lateral shoulder pattern are all designed for grasping the ground. At the same time, the 3D active noise reduction pattern system patented by Mapai, together with the diagonal transverse grooves, works together to weaken the impact of the road surface and weaken the noise continuously, giving it a quiet feature. The "ultra-high turnup" carcass structure is strong and rigid, and the positioning of MC5 in the continental brand series itself is "the master of silence in motion control tires".
