someone please tell me why the hell my nittos wont hook for ****! i was on the highway, and almost got sideways in 3rd gear cause they wouldnt stick ill spin thru 1st 2nd and 3rd, and then i stop in 4th. and no im not at wot either, id say b/t 1/2 to 3/4 throttle. and yes, i do heat them up first. i dont drive like a madman all the time, but when i wanna go....i wanna go. and do it safely, not sliding into a divider

What air pressure are you running? When I ran 16" nittos;
street=23psi, track=15psi

My Yokomamas are the same way.. I hate them. Came on the car. Sure glad I didn't buy them. Just don't know what to replace them with. Without spending an arm and a leg.

it was cold outside. but the thing is...theyve never hooked since i had them.

Start at about 15 psi cold and see how that does on a warm day. You probrably still won't be able to dead hook from a dead stop on the street but a low roll should be no problem.

I bet it was the temp, i smoked my tires going 30mph yesterday with 18psi in them on the street. normaly i might bark them or have minimal spin but they went up in smoke, didnt even try & hook. it was in the 30*-40* range here.
mine are 275/40/17's as well good luck.

ill try 15 psi. is that what you always run on the street? thay cant be good for gas mileage...

GM Muscle

I actually run my 315s as low as 12psi cold on the street, that's usually what I run at the track so alot of the time I just leave them at that. I have no idea about gas mileage but the tires are wearing nice and evenly and I've never had any other problems other than spinning them on the rim alittle at the track.

BTW: I also ran my old 275s at around 15-20psi all the time and those held up well too.

spinning them on the rim? ouch. that cant be good. ill try 15 and see if that helps. but its really cold out so i doubt itll have much of a diff now.

Seans Ws6

run ur air pressure at 15psi

jammon46

how long have you had them? mine took a while to break in before they started to hook up.

99FormulaM6

iTrader: (21)

well theres almost no tread left now. but even when i first had them, they didnt hook well. and since i need new tires now, i dont want to buy them again if i dont think theyll work for me. i might just pick up some more, and try 15 psi on them

What kind of nittos are they? Im looking at the street radials, 555r I think. I might look at something else if thats a problem.
Thanks

mine are 555r's. whats the big diff b/t the 555 and the 555r's? i know a guy selling some barely used 555's that i might pick up

jammon46

555's are the "extreme performance" road racing tire. 555r's are drag radials. I have 555's and they hook pretty good on a good clean surface.

99FormulaM6

iTrader: (21)

do the 555's last longer than the 555r's? or do you know?

GM Muscle

It depends what 555 you talking about. There is the regular original 555, which is a true street tire and would never really hook in my opinion but it should last like a regular radial. Then there is the road racing 555RII, which I believe jammon46 is talking about, then of course the 555R. The 555RII and 555R are the exact same compound and tread design, the only differance is that the 555RII has a stiff sidewall instead of the soft sidewall that the 555R has. So basicly the RII and the R will probrably last about the same amount of time.
