CASING-REINFORCEMENTS
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 cross-laid reinforcement protecting the whole tyre casing. The crown and sidewalls are reinforced to provide maximum protection and durability.
RUBBERS
Rubber's characteristics give the tyre different performances. Rubbers can be either Mono-Compound or Bi-Compound.
Invented by Michelin in 1995, this is a mix of two rubber compounds in a tread providing central rolling efficiency and lateral grip (e.g. MICHELIN Power Endurance which combines Grip Compound and X-Miles Compound).
