I've had them for two summers and about 10k kms on a Ford Focus ST250. When I was buying them I was looking for good tires at a fair price and these were the newest model available at the time.
Dry: In the dry they have good traction, predictable handlings and good comfort for a UHP tire. Breakaway is communicated well and they don't surprise you out of nowhere. Lift of oversteer is easily achieved and controlled. They do wheelspin a bit in first gear if you are a bit more enthusiastic with the throttle but that's expected on a more powerful fwd car.
Wet: They have good and predictable grip in the wet, good aquaplaning resistance and stop quite well.
Others: Rim guard is somewhere in the middle, not as big as Bridgestone but better than Hankook. Sidewall design is good, comfort and noise are good for a uhp tire. Wear has also been good for me, I expect to change them due to age and not wear but then again I don't do that many miles a year.
It's a tire I like and would recommend. Price to performance is good. Would consider buying. I got their Wintrac Pro Plus to try this winter so I've been satisfied with Vredesteins as a whole.
