I fitted Continental All Season tyres to all 4 corners of my 2018 NX. They have been on for 18 months now.
The interior of the car is so much quieter, both in the wet and the dry. I have driven the car over sloping wet grass, where the original tyres gave up, and they never lost traction once.
I had considered changing the car, but with these new tyres on it really does feel like a new car, so has potentially saved me quite a bit of money 😃
