I was informed that it helps in cruising in rains too . but i dont belive the source through which i got this
Asymmetrical tyres are those which have a tread pattern that is different from one side to another. (OK, sorry for stating the obvious!!)
Tread patterns vary, some giving particularly good dry grip, some have characteristics designed to enhance wet performance. An asymmetrical tyre offers the best of both worlds by combining the two patterns across the width of the tread, unlike symmetrical tyres, which do their job adequately, but not spectacularly. Symmetrical tyres are popular though, since they are typically cheaper, and don't give you headaches while rotating the tyre.
Regarding the construction, The outside of the tread pattern consists usually of larger stiffer tread blocks that help with cornering performance by increasing cornering stability on dry roads by offering greater contact area. This also helps to reduce tread squirm and heat buildup on the outside shoulder.
The inboard side usually features smaller independent tread blocks to aid wet and/or winter traction when driving straight ahead.
And yes, your source was right!!
