This is my last review with these tires and I have reviewed them at various mileages on my A5 3.0 tdi Quattro sport.
After 32000 miles the fronts are down to 2.5 - 3mm but the inners of the tires are worn to almost slick but 75% of the tread across the tire is fine. The rears are worn down to 4-5mm so still have life in them, I should have rotated them at 10k intervals and I would easily have hit 40000 miles wear on these tires.
At the time I bought these tires money was a bit tight and I took a punt and to be fair these nankangs have been fine. The dry grip is acceptable and the wet grip is acceptable too, but this is down to the Quattro system on the car. Now that the fronts are almost shot in the wet the front end has very limited grip and slides easily when pushed gently on small roundabouts, so no high speed bends for me now. Even in the dry the front end is now skitterish at low speeds into bends and I know the tire is almost at the end of its life but in the dry a premium tire would not do this. I feel this is down to the very hard compound the tires have and it seems to be getting harder as they wear.
The tire noise from day 1 was loud and they have been getting progressively louder as the tires have worn, it's a deep humming sound which simply is not acceptable. I feel this tires would be great for lots of town driving at low speed and the noise is acceptable, but step into a motorway and it's a different ball game. My mum even commented on the tire noise on a recent trip to Southampton and that says it all.
I won't be buying budget tires again and will go for mid range to premium like Avon, hankook, vredestein etc.
