| Are not ( unsure here ), tires used on specific cars that show maximum gains and based on there specifications and horsepower rating of the car / vehicle there mounted on? Clarification: You can hurt your performance by overmatching the car with to much contact patch of a tire or to much massive based on the cars TQ curve. Like putting 315 slicks on a 450rwhp turbo car. Rotating that mass one would think would absorb more TQ and power and result in a slower time. I guess case in point would be this running 8.54@169.44 on BFG drag radials 325/50R15's with only 10.4" of contact pre tire. Which like all dragracing tires, looses patch width on launch. So less than 20" total inches of tire to transfer 1200rwhp. 
When they could have used 345/55R15.
