Ya,if its a 10 or 11 sec car,there's no need to run a 14 X 32 tire. In reality its probably slowing the car down.



Definitely, I know this SS/KA car shaved off considerable ET by simply going from a 14x32 radial slick to a 10.5x30 radial slick





This could be because he went to a smaller diameter tire. But, I would agree if the tire is lighter it will help.
