CASING-REINFORCEMENTS A tires casing is made up of threads, the thickness of which varies according to the tire range, makes it robust, flexible, efficient and lightweight. The more threads there are, the finer they are, making the tire lighter. On the contrary, the less threads there are, the bigger they are, making the tire stronger. TPI (Threads Per Inch) refers to the density of threads per inch. Thanks to its additional protective ply running from one bead to the other, Michelin SHIELD CASING improves resistance to external attack on the sidewalls and reduces punctures due to impact or pinching. 3x60 TPI casing which is lightweight, durable and robust with a very high-density reinforcement ply. Tubeless Ready tires can be fitted without an inner tube provided that a tubeless wheel is used, the maximum pressure is not exceeded, sealant is added and the tire pressure is checked before each ride. Tires with the E-Bike Ready label can be fitted on electric bikes (maximum 25km/h).
