True, but if we say "all other things being equal", it's a mixed bag. Please be aware that the definition of "handling" is not the same as traction or grip. Handling means the "feel" - AND - if the tires are otherwise the same, a bias tire has a softer transition at the peak traction point.

False. Toe-in is not the thing that determines how predicable the handling is - except to say that toe-out leads to a more unpredictable condition.

I think vehicles need negative caster for straight line stability regardless of the type of tire.

True, but that particular property has been dialed out of modern radial tires, so it isn't as true as it once was.
