They weren't
COMPLETELY useless like that guys Camaro but it was a front wheel drive car which has better traction. What would happen is they would "drift" sideways in snow/ice at anything over 25-30 mph.
VERY disconcerting and unsafe!
Problem was the off-lease Hyundai was a Florida-car (lol) and down there believe it or not those tires would have been completely fine even if they wore out fairly fast... Ling-Long is a (relatively!) legit tire company these days.
In a harsh New England winter however they proved insufficient.
