These are a solid wet weather tyre with excellent wear properties over standard OEM (Bridgestone Re040) tyres. They are a little skidish during hard cornering on dry services and lack a fair amount of dry grip. I'm a little gun shy after unpredicted drift into a bend. I will opt for a more grippy tyre to enjoy more spirited driving. As a daily drive its a good value tyre though, particularly for your grandmothers car.
