The N PRIZ SH9i have a pot hole and mileage guarantee which is very handy if you drive in area that is prone to pot holes. They have an improved block reliability and braking performance by way of a 3D section design. The N Priz SH9i has improved drainage performance for driving on wet roads by increasing the width of the three channel main groove and the shoulder lateral groove. It prevents abnormal wear and enhanced noise performance through applying the design of an equal division of block stiffness. With the asymmetric tread pattern design, the outside section enhances handling performance. The inside section enhances tyre grip by improving drainage performance for driving on wet roads. These tyres are ideal for drivers who have high performance vehicles and need a tyre to match.
