Changed to winter/all weather tires, car handles like a boat
I've just changed from my Michelin Pilot Super Sport to Kumho Solus KH21 225/47/R17 (all weather tires, which are really winter tires, I had almost identical tires on my Honda, they were fine)
I am driving on the highway and I notice that the car feels like a boat, I've never experienced worse handling than this, even on my Toyota Echo
Is this really due to the tires? Steel rims can not be to blame?
Can the slightly larger profile be the culprit?
Or is this normal for all winter tires? Although I've had winter tires before, and no such thing.
