These tyres constantly change shape as they warm up and cool down with speed changes. The vibration in the steering and noise when this happens is quite bad, though it goes away with more time driving. These tyres are probably fine for low speed town driving, as this problem occurs when transitioning between motorway/freeway speeds and town speeds.

Bought 4 of these for S60 D4 VOLVO.All in under £200 just over a year ago.
They replaced used set of PZEROs that were on there. And I tell you what, I cant spot the difference.....

Wet and dry handling is just as good. Never felt scared of as if they are going to give way or break away.
Wear also looks good for a 10,000m after a year.

Only one problem was the front nearside developed a puncture in the sidewall which was the only downside to these.

Brand snobbery has gone a long way.
