I've had these tires on my Opel Vectra C station wagon for about 4 years now.
The tire might be good for lighter cars, but since Vectra weighs about 1600 kg unloaded, these tires had a tough job keeping the car rolling... They are too weak for this car. It felt like the car was floating on water while on dry road. I tried different air pressures and in the end I had to get them up to 3.3 bar to keep the car from giving me sea-sickness.
Wet grip is also one of the issues these tires don't seem to handle well. Aquaplaning happened quite often, even at lower speeds (70 km/h).
They don't have a rim-protection edge.
In "sporty" or spirited moments, the tire gives very little feedback about what is going on with the wheels. The sides are soft and car seems to tilt a lot (even after going -30 mm + stiffer shocks on all four corners last year).
On the other hand, they were cheap, so this is a plus. Also, they wear quite slow (on our cra**y roads in Slovenia).
Would I buy them again? No. Specially not for a heavy car like my Vectra.
p.s. Father in law has these on a Citroen Picasso mk1 and is quite satisfied. Lighter, softer car. And a lighter right foot, too :)
