A tyre’s casing is made up of threads, the thickness of which varies according to the tyre range, makes it robust, flexible, efficient and lightweight. The more threads there are, the finer they are, making the tyre lighter. On the contrary, the less threads there are, the bigger they are, making the tyre stronger. TPI (Threads Per Inch) refers to the density of threads per inch.
High density reinforcement in the tyre casing to provide strength at the crown and minimise punctures. Aramid is stronger than traditional materials and is much more cut resistant and is the material used for manufacturing body armor.
