Sorry for another tire thread guys.......searched for a bit but really couldn't find the answer I'm looking for....

07z, supercharged with 590 to the wheels. Only 5,900 miles on the car so it's still on the stock runflats. They. Are. Worthless. All the way through 4th really. 1-2nd gear forget about it.

The car is used on sporadic weekends, DRY weather only. Don't plan on road racing but I do intend to drive the car if you know what I mean.

I'm looking for the best tire that will let me lay down most/all of the power. Car has Borla Stingers and ARH's so it's pretty loud already....little worried about the noise with the Nitto's.

I guess my real question is - will I be able to lay the power down with the MPSS's? Or is my better bet with the NT05's....Not looking to add to noise level or lose handling as much as possible, but I do need some traction. Badly.

Seems like a hard trade off. Any guidance you all can give?

Thanks

MP I had that on my last set up....

Im about same hp as you and i run mpss most of time but tbrow on nitto nt05R when i go to track or wanna have fun.

The nittos in straight line are waaaay better at first and second w just a bit of squirm at top of 3rd.

oh.... i dont notice any diff in road noise, but thats hard for me to hear anyway. Hope that helps.

The PSS have more grip than the NT-05s, but for straight-line the NT-05R rears have much better traction than the PSS.

Toyo R888s will have both cornering and straight line grip, but you will only get 5-6K miles on them. They also whine on the street due to the tread pattern, but a nice sounding exhaust covers most of that. I use PSS as my street tires, but change to R888s to drive to road course events. My PSS replaced my NT-05s which I liked but the PSS have better traction and much much more tread life (3X).

So, are the R888's close to NT05R's in straight line traction? But markedly better for corner carving?

I have the NT05R's now, and just miss the ability to slice and dice, like I was able to with the PSS...

Unreal

Not as good as nt05r in straight line but turn great. They are a road race/turning tire that is really sticky, but doesn't have the soft side wall of a drag radial.

Megatronss

thats helpful, thanks! How were the nittos grabbing corners?

Megatronss

Also, how well to the PSS's fair straight line with that amount of power?

sounds like a really tough call. I'm not going to get two separate tire sets either unfortunately.

ratomicZ06

I dont do corners, lol.

Actually the car will oversteer w mpss front and the nt05r rears, buts that ok bc i change them for a purpose. They dont wear well either, but thats ok too.

Megatronss

Lol ok...soooo still a little stuck here!

There is no perfect tire. You either give up turning, or life, or straight line. Rank those in order, then that will tell you what tire.

The best solution is multiple tires, but if you don't want that, then there are trade offs.

Drag radials drive fine on the street and can take any legal cornering just fine. If you are into rallying up canyons or road racing, they don't work well. So when people say they don't handle well, you need to figure out how hard you push tires in corners. Most people never come close to pushing a tire on the street besides straight line.

Megatronss

makes sense.

#1 straight line traction
#2 cornering

dont care about tire life. Car will get driven 500 miles a year MAYBE.

I guess the real question is how well will the MPSS's hold up to the power in 1st/2nd?

AzDave47

PSS won't hold in 1st and may hold in 2nd if it/they are warm. R888s won't have the straight line traction of NT-05Rs but should be fine for street pulls except they won't dead hook in 1st from a stop.

At 90* with 325 MPSS, my 602/490 HCI car hooked in 2nd at 40 MPH, hard throttle in 90* weather. It would have been different at 60-70* and may not have held with hard throttle at 60 MPH in 2nd.

Unreal

They don't at any serious power level.

When you say cornering, define that? Road course use? Auto x? Aggressive canyon? Would you be willing to trade better straight line for less cornering or the opposite?

NT05R is straight line is #1 concern and willing to give up some handling. No autox/road racing.
R888 is handling is more important but still hook decent in straight line. More ideal for autox/road racing/extreme street turning.

AzDave47

good, quick summary.

Megatronss

Thanks for all the help.

By cornering, I mean spirited street driving and carving canyon roads yes. Would the nittos's be that much of a drop off? I am more concerned with straight line traction yes, but not at the expense of a huge drop off in handling.

Hope that makes sense.

Unreal

Hard to say. Do you drive through canyons tires squealing? If so r888s.

I just got the super sports and really like them. I'm not at your power level but they grip really well. Like others have mentioned there is not a perfect tire. I had the NT05's on my 07 z06 and liked those as well but went w/ the Michelin this time for extended tread life.

AzDave47

I went from NT-05s to PSS. On the same roundabouts, the NT-05s generated 0.93-0.97Gs the PSS 1.12G so quite a bit more grip. I got 7K miles including track days out the the NT-05s and 23-26K miles including track days out of PSS, so performance, treadwear and value go to the PSS.

The michelins all the way..

Unless you step over to the NTO5r's.. They are a lot stickier and last about the same as the NTO5's. I've had them on a few of my rides. They work great for about 750hp or less.
