So this winter i have experienced alot of traction issues. So i checked my tires, the studs are pretty much gone and i have huge problems in snow. The bigger question is why my car feels like (swimming) i dont know how to pronounce this phenomen. It happens mostly at 80+ km/h and on turns. It just doesnt feel right. May it be also because my winter tires are like 4 years old somekinda hankook ones?
