I've had a set of 165 Vredestein Sprint Classics on my 4/4 for 10 years now, flipping excellent tyres. They still provide all the grip I want, they let go under extreme abuse very gracefully and predictably, and they are still nice and black and sticky, no sign of going off - probably because they live in the dark in my garage when the car's not in use.
The only downside is the cost, currently around £160 per tyre. I think next time I'll switch to Vredestein T-Trac2, they have a good reputation among 4/4 owners.

I was an early adopter of the T-Trac2 here on the forum and today there are quite a few users of this tyre on the 4/4.
Last autumn I bought my third set of T-Trac2s. However, I was disturbed by how eggy the wheels ran, at 90 km/h the car shakes sideways even though I had the wheels rebalanced twice.
Then there was a discussion, even here in the forum, that the T-Trac2s come from India these days. I looked it up and yes, my new set comes from India. Nothing against India, you would think the workers are just as good as those in the Netherlands and the production machines were probably brought there and set up again. Anyway, it's definitely my last set of T-Trac2 because I'm already annoyed. With the first and second set, the 4/4 drove as smoothly as a billiard ball.
