all u guys running 255/50/16 ET street radials...

what is the best cold tire pressures?

 

Cold tire pressure for what?

 

for 255/50/16 et street radials... to hook at the track

 

I was running 17 psi cold when I ran those tires...Hooked 1.55s all day long with them with 16x8 stockers all around...

yea i was running 18 psi this past weekend... this upcoming weekend i think im gonna try 17 or 16 psi cold

 

nice aba what is your stall??

 

I run a Vig 3600...My current set up is Bogarts, 275 60 R15 M/T radials, QA1s, and 4.10s...we'll see if that whittles away at the 60'...

how is the 3600 vig on the street?

 

I run mine at 22lbs. cold, or there abouts. Dead hooks every time on test and tune nights. (no track prep) My 3600 drives just fine on the street with the 3.73 gears. Higher gears equals more gas pedal to get going.

 

20Psi for me. The pressure doesn't fluctuate too much from cold to hot in these tires. M6 fullweight, 16x8's all around low 1.70's consistantly. I actually do better with 20-22psi then lower pressures.

 

Its fantastic! I've never driven anything like it before...It drives like a stocker until you nail it, then it hits so hard its unreal...I could easily DD the car with this converter...

with that i decieded to go with a 3600 vig... f*ck that im not gonna be a pu$$y if im gonna spend $400 mineaswell go big or go home....

and i have heard around 16 psi cold in these tires are the best... i dn tho

 

You want as much air as possible and still have traction. To little air and you might screw up the footprint of the tire. My Nittos like low air pressure, the MT don't need to be run that low.

 

yea well i was running 18psi cold.... and they were spinning a little of the line...im gonna try 16psi cold sunday. and if it is worse i will up it to 17psi

 

If you stay in the teens with the air pressure you may never find the sweet spot. My bigger Hoosier DRs like 20-21 psi. And when I say like I mean wheels up 1.45 60's

Start at 22 or 21 make a couple of passes and if they spin then lower them one psi at a time 'till you find that they hook better or get worse.
