This is not saying anything bad about anyone in particular......but MOST racers don't understand tire pressure.

Brief rundown, although I have done it before in other threads. Lower pressure lets the tire "cup" in the middle at launch. Basically just using the edges of the tire. This is beneficial almost all of the time, because 99% of cars are overtired for the power they have and it makes it tough to get the car "on the tire" early. The more air you put in the tire, it flattens the tire out early and actually puts MORE rubber on the ground early, where VERY few cars actually need it.

Lets look at this from a realistic standpoint. Many bracket guys and or heads up guys run a tire nearly as big on their low horsepowered door cars and pipe racks, as you see on fuel funny cars and dragsters. Think about that a minute..............So if that is the case, do you really think your 800 N/A hp bracket car with 15x33s is "blowing the tire off" at the hit?............hardly. As with MOST cars, it crushes the tire at the hit as it is trying to drive the rims into the pavement. After flattening the tire, it and the suspension rebound, hopping the rear of the car and spinning the tire. This happens SO fast, guys think they blew the tires off at the hit. This NEVER happens
