I don't trust Sailuns. Two people I know, have had problems with these tires, both in the wet. A buddy of mine had them on his 95 m3. Bone stock car, he said they don't grip in the wet, as he spun his car at an intersection near work and all he was doing was turning with the advanced green light.
I have read up on them and some of the reviews from users say they fail in the wet compared to Michelins, Continentals. But for bang for buck sometimes you find a good tire at a cheap price. I use Hercules for winter. $325 for a set installed. Similar tread to the General winters, pretty good so far.
