Street driving nitto's 555r's..psi?

[Chuckie B]

Have a set of Nitto 555r's waiting to go on after i supercharge my car... what psi should i run on the street? not going 2 drive the car as much as i use to if everything works out with the kennebell kit.

you can do 25psi for good grip on the street, for the track you'll want to do lower then that.

I ran 20-25 street and 15 for the track, this was 555R. I got 1.9 60ft track and hooked alot harder on the street, enough where and AWD car would have all it could do to take me.

My friend was making 460/490 in his 04 Cobra with 275/40 555R and spun only in 1st dead hook in 2nd gear. What so you have for suspension right now?

BTW..when did you SC your car??? I totally missed that LOL.

i have 245/45/17's on rite now. way to small anyways.... s/c was installed a couple weeks ago. suspension - eibach prokit, j&m upper/lower control arms

yah i have 275-40-17's... but from what ur saying doesnt seem like that will make much of a difference lol.. but i'll only be around 390-405 hp so that close to a 100hp difference between me and you could make the diff in hooking or not.
