Pulse groove technology Pulse Groove technology contributes to a significant improvement in wet performance. The highly modern Pulse Groove Pattern Technology combines pulse-shaped grooves with small centre deflectors to optimise the water flow. This results in improved water drainage and, concomitantly, improved grip and optimised slip behaviour of the tyre in wet conditions. Technical optimisations T32 technical improvements in construction and rubber compound Convincing contact feeling More contact with the road - with optimised neutral and linear handling Special GT version Bridgestone has developed the tailor-made T32 GT with an optimised tread design and special construction. This produced improved handling in the wet, better grip and a 10% longer tyre life compared to the previous model.
