I am currently running a set of Nitto NT-05s in the 285/335 combination. My current tires are toast and I am in the process of getting new tires. I plan on doing one of 2 things:

1) Michelin PSS all around in the 285/345 combination.

2) Nitto NT-05R drag radial out back in the 345 and regular NT-05 in front in the 285 width.

If you have a H/C car in the 550-575 RWHP range how well do the Michelins grip from a 2nd gear roll at WOT? Will they hold or break traction? From what I hear the drag radials will most definitely hold and there is no comparison if you are talking about dry straight line traction only.

I did do a search. I am interested in H/C cars only.

Thanks in advance for any replies. I know there are already tons of tire threads.

Chonger,

I have 596 RWHP, with a 4.10:1 diff gear set and Michelin Pilot Sport PS2 tire. I have no traction in 1st or 2nd gear. I only gain traction in 3rd gear from a 70 mph roll.

I went from 335 NT05's to the 345 MPSS. Not positive what power level it's making. Still haven't gotten the girl to a dyno to finish WOT tuning. I'm guestimating 575'ish........ Anyway, traction is better, but it still break loose in 2nd when it hits about 5k. This is on asphalt roads, not a sticky track. The NT05's could not hang with these. I suggest you consider 19's for the front. I HATE the way the 18/285's feel. Too mushy and not all that responsive. So much that I have some 19's on order to swap out the 18's.

I just got my car back from the shop yesterday, tires and alignment today, I can give you some feedback in a couple days, supposed to get up to mid 50s (and we on the east coast will take it) and I may do a little spirited driving over the weekend... I, like you did a lot of research and these seem to be the tires for street and occassional track use...

I'm at 575rwhp. I had nt05's now pss. At 43° outside a new accord coupe v6 got me off the line. Cold temps suck. Neither tire can handle a stomp of the gas in 2nd. Rolling into the throttle helps. But once the cam gets strong at about 4500rpm's wheels get loose! I have no problems with the 18/19 combo. Why go to 19's in the front? You're just asking for pothole damage and a less forgiving platform at the limit.

For me, the incredible rain capabilities& massively long treadlife make me love the pss. But I'm hoping Michelin make the pilot sport cup 2's in Z06 sizes soon!

They probably won't do the PSC 2's in Z06 sizes as they already make the 19/20 PSC-ZP's specifically for the Z06/Zr1

I just checked and even though the MPS 2's are listed as streetable track tires their wear rating is 180. It seems much of the technology used in building the PSS has been put into the PSC-2. I still doubt they'll make it in Z06 sizes, but probably do 19/20 PSS-ZP's for the new C7 Z06 and say that's enough tire sizes f and models for the Z06/Zr1

I do. I have your #1 combo. And second gear roll starting at what MPH? At 40MPH, the Nitto Invos would hold pretty well and these MPSS tires grip better than the Invos did. Now first gear at 30-40MPH? Forget it. But I leave traction control and active handling on during highway rolls.

That said, the MPSS tires went on late last year. I haven't run them in the summer yet (these being summer tires).

I have a second set of wheels on the sidelines waiting for some R compound rubber. I'll either go NT-05 + NT-05R or go with Hoosiers all the way around. Most likely the latter.

Side note, asphalt is slick because it's infused with oil. I'm thankful that the major roads here are all concrete. I can break loose in third gear very easily on asphalt.

I am running 558rwhp/522rwtq and the ZR1 size Michelin PS2s in 19/20 combo. No traction in 1 and 2 if just putting it to the floor. Roll into it in 1st and you can hold about 3/4 most of the way and get the last 25% just before the shift. 2nd will get loose going in, but just roll into the throttle again and it will get it. 3rd is off and on. Sticks hard somedays and gets sideways others. I am running the Pfadt street alignment on mine. Moving to the performance street, not for traction issues.

Thanks guys for all who replied. It looks like I will probably go with the DR's out back. I want to be able to enjoy the full potential acceleration of the new H/C package. I did the H/C swap last year and can't fully enjoy the new power. Nothing but total spin in 1st and 2nd. I imagine the DR's will probably even hook in 1st. Car is now making 556 RWHP. It picked up almost 70 RWHP from a full bolt on setup after the H/C swap.

I have 555whp - they have limited grip in cold temps, but once they warm up good, they work pretty well. Of course, I don't push things to hard.

The 18/285's have a lot of side wall. It's like having balloons on the wheels. The 19/295 is a nice compromise. Still enough side wall, but not so much that the steering feels lazy. I suppose 18/275 would work OK, but with the added tread depth of the PSS tires, I have my doubts.

I am currently at 561/505, and definitely cannot hook 1st, in any weather. 2nd gear 5k rpm punch isn't an issue in 70 plus air temps or 60 plus but with putting some heat in the tires.

There in lies the issue....when the air is conducive to making power, the tires cannot hold it. I was at the dragstrip last Sept, and althought the low 60's temps were great for power, I could not hook rolling into it in 2nd gear. 1st was a joke, and even the 2nd-3rd shift caused the rear end to wiggle a bit.

Bottom line, you have to make a decision on whether straightline traction or carving ability is more important to you. In this case I don't believe "you can have your cake and eat it too" rings true.

the mich pss will last longer, the nt05r will hook harder.

AzDave47

The pss wil alsol go around corners much better, but you want the hookup so NT-05R's in the back and match with NT-05.s in the front would be what I'd recommend for you.
