A tire’s filler is the part that rests along its inner supporting wires. These components are responsible for reinforcing the exterior rubber casing of the tire, and they also make the material harder to puncture. This is essential for increasing a model’s overall lifespan and ensuring maximum performance when driving.

Carbon black, Silica, and amorphous precipitated silica are used as tyre fillers to reinforce the rubber tube & improve vehicle performance. To improve tyre properties such as tear resistance, abrasion resistance, and tensile strength, a filler is employed. Silica's main purpose is to boost the tire's rolling capacity.
