OK this might not be the ideal car to test such tires on but bare with me on this one. Because the Beetle is an old and - by today's standards - quite unusual vehicle, small changes like a tire change make a huge difference on the car.
I have to say, I'm very impressed with these Contis. I had them for almost 3 years and their wear is slow and even.
In terms of comfort and refinement they are well above average, on par with the Brdigestone Turanzas I had before.
Handling-wise they are very progressive and offer decent responsiveness and grip for a tire of this type.
More importantly though their Bionic design (which increases the tire's contact with the road by ~10% under hard braking/acceleration) was very much appreciated on a couple of emergency brakings, something best avoided with an old Beetle! But nevertheless they performed impeccably in these conditions as well as in a couple of high speed manoeuvres on wet roads.
I was also happy to notice a considerable decrease in fuel consumption especially during motorway cruising.
I would definitely recommend them and I'm more than likely to replace them with the same ones.
