A newish set of these came with my Suzuki SX4.
They accentuated the cars hard ride, and the steering had a `sticky` feel in the straight ahead position.
They grip well on a warm dry road, but are very poor in the wet .It was very easy to spin the wheels pulling out into moving traffic on a wet road,(no traction control on the SX4).
I am no expert, but the tread design seems little more than slicks with longitudinal grooves, as the lateral grooves very quickly wear away from new.
I know this is contrary to the vast majority of opinion on here, but it is what I have experienced, and I guess the test comparisons are done on brand new tires
I threw them out at 5mm, and fitted a set of cross climates, which provided the same kind of huge improvement they had done on my Saab 9-3.
Improved steering, wet grip, and ride, and much, much quieter
