Tyre: Grandtrek ST30 ASY


Straight from the Dunlop Tyres ‘all - weather’ range of tyres, the Dunlop Grandtrek ST30 ASY tyres are known for beating any kind of weather and performing admirably in dry or wet conditions. Known for Dunlop Tyres’ signature attributes of comfort, manoeuvrability and precision, the Dunlop Grandtrek ST30 ASY tyres bring a touch of class with an enticing design. A part of the Dunlop Grandtrek ST tyre range, which includes ultra high performance tyres such as the Dunlop Grandtrek ST20 tyres, the Dunlop Grandtrek ST30 ASY tyres are high load bearing tyres with superior traction & grip. The perfect fit for 4WD vehicles, the Dunlop Grandtrek ST30 ASY tyres are the original equipment for several trucks and SUVs, including certain latest models of the Toyota Highlander.‘ASY’ in the Dunlop Grandtrek ST30 ASY tyres stands for “Asymmetric” and refers to the tyre’s asymmetric tread pattern, which provides enhanced performance in wet and dry conditions.

Jointless band technology: The Jointless band technology of the Dunlop Grantrek ST30 ASY tyres provides improved handling and tread life cycle, while reducing vibrations. This is achieved by placing spiral wound nylon at crucial places which gives perfect shape and longer life to the tread. This enhances stability, enabling you with better control and minimal disruptions.
Pitch tread design technology: This technology comprises carefully designed tread blocks which create the optimum frequency to counter- react with and reduce noise. As a result you experience such a quiet drive that you can barely believe you are driving. 

This tread pattern is in fact one of the major factors that allow the Dunlop Grandtrek ST30 ASY tyres to showcase highest standards of control, comfort, precision and safety.As part of the asymmetric tread pattern the tyres exhibit circumferential grooves in the inner shoulder. These grooves help in expulsing excess water from the treads and deliver strong wet traction and grip so you can drive like you always have, rain or not.Along with efficient steering response and manoeuvrability in any weather, never again will you have to buy an extra set for a different season.

I have not had any occasion to drive in snow yet so cannot tell whether they work well in bad conditions.
