What Are The Differences Between Asymmetrical And Directional Tires?

 I have examples here of two different types of tires and two different distinct tread patterns the tire is a Pure Performance summer tire that is considered unidirectional that means that the tire is designed to roll in One Direction of rotation each sidewall would be indicated with an arrow for a rot if on right side of the car or a rotation if on left side of the car now this tire has a center rib a solid Center rib and

 the purpose of a solid Center rib is to provide a continuous contact patch at the center of the tire to improve wet and dry braking and handling and basically to improve steering response on directional changes water evacuation takes place circumferentially on the tire even though some people are of the opinion that directional tires are superior in the Rain the largest percentage of water evacuation on any Tire takes place circumferentially on the left we have an asymmetrical tread Tire an asymmetrical tread tire has different tread features you'll notice that the tread blocks on the left of this tire are  larger than the ones on the right asymmetrical tires are designed to be mounted specifically with the certain shoulder or certain pattern to the outside in fact the sidewall will be branded with outside so that they're properly installed on the wheels the purpose of having larger tread blocks on the outside shoulder is to

 improve the handling of the tire whenever a car turns in a corner there's a weight transfer to the outside shoulder of the outside Tire when the weight is transferred to the larger block on this shoulder there's less deformation therefore Cris crisper steering response you'll notice even the isometrical tire has large circumferential grooves and this is to improve wet tracks both these tires would be quite efficient on wet surfaces the type of Tire chosen depends to a degree on the consumer's preference for tread pattern and for certain ride attributes.
