I recently bought a Mercedes C220 estate with Avon ZZ3 on the rear. When I got on the motorway after collecting the car I thought I'd bought a lemon with a worn diff or wheel bearings. The road noise from these tyres is awful.
Done over 500 miles and for the price they are a good tyre. Good amount of grip in the dry and they are fine in the wet (So far) I do lots of mixed driving and the wear rate is excellent
These were initially very good and provided good grip on wet/dry. After around 5000miles the noise started to increase but the performance remained. I have driven on different road conditions and the tyre kept up very well. I have used Michelins, Bridgestone & Pirellis prior. They are still better as I bought this due to unavailability of those at the time of purchase.
