3.2 TL

Ok i read before that when you go to the track it is a good idea to deflate your tires a little bit. How many psi should i deflate the tires if i were to take my car to the drag strip. Is it the same amount regardless of tire (I have the stock tires)? Has anybody heard about bleach burnouts, where you soak your tires in bleach and then do a couple of burnouts. That is supposed to make your tires stick really good. I haven't tried it though.
