Very good tire,manufactured in Serbia with Mishelin supervising.
Overall I do not recommend them. He should stop manufacturing. Nice design, it has Michelin behind, but very cool tires. God forbid you, to put the emergency brake ... on a dry road, does not stop, you're still going. On the wet road or at the speed of 30-50 mph (50-70 km / h) you can not feel safe. In addition, very noisy, vibration, the tire shop told me to change them. They had a pretty long life, but no comfort. Lost money.
These was the cheapest tires for my car, and due the good Michelin reputation I´m trying a pair on my VW Polo front wheels. The aspect is somewhat wierd when on my rins. I use Michelins pilot sport on the back wheels and they are totally differet. The Syneris are taller and narrow when compared to Michelins. The confort is very good and it is silet, but the lateral walls are very weak, despiste it has an awesome rim protector. I tryed only for a 100 km, but is slightly understeerer on dry. On the rain its very good. It looks like a decent tire for the price. Structure is poor and its slightely tall, so your car can gain some height. Due the soft side wall it wont change direction as fast as a Michelin, but its confotable, grippy and cheap. Not so bad at all.
