I need two new front tyres on my s3, i was going to go for avon zz3's as they are already on the car and they seem a good tyre, however my local tyre supplier said they have been dicontinued. They said that they stock kumho ecsta tyres and that they are on a par with the avon. I have had a look and i think the model is a ku3194y. My mate who is a mechanic said that kumho are now as good as any of the other leading companies!? I would be gratefull if anybody could help.
