street tires at the track - any tips?

Hi Guys,

next weekend i´ll go to the racetrack for the first time with my new engine. Since i don´t have some better suited tires for now i have to use the street tires 225/70-15 that i already have (they are near new).

Is it recommended to lower the air pressure also with street tires? Do a little, big or no burnout with street tires?

I´m new to this, been once to the track with my valiant - with the slant six.....now it´s a 408 with some serious torque. I know that´s not the best combination, just want to have some fun, hope for some 12 sec. runs. Rear is 3.73 with suregrip.

Thanks for info!

Michael
