i want to get the most out of my launches, but my tires are a bit worn out, not a crazy amount but fair and i want to know whats the lowest i can go in psi on them, the 195s it comes with....

 

"0"

You shouldnt need to go any lower than 20psi on street tires. I personally never went below 22-24 on drag radials.

 

Running lower pressure will make you spin your tires more wont it?
I thought lower pressure only works for slicks. With street tires, you will lose the center section of the contact patch.

 

On stock tires it is pointless to even consider being consistant with drag launches. Get drag radials or slicks. But to answer your question 22-23 psi is about as low as I would go on stock tires. You might hit low 2.2's 60's sometimes.

 

22 psi sounds good thx guys

 

Just to add, when I go to the track, I run mine at 17 psi +/- 1 , that's on Potenza 910's 205/50
