? about tread design on BF KD's
 

you are looking at a 275/40/75 bf goodrich g-force KD tire...i was studying the tread for a minute, and i was wondering why there isnt an extra groove in the other center of the tire?...

because they are left and right specific tires.

right, and they are directional....what are the benefits of having more tread towards the outside of the car?

cornering?

asemetrical tires typically raise cornering ablility.

correct on the cornering.
