Hoosier R6 ????
Looking for feed back on guys running the Hoosier R6. I'm making 625ish rwhp and looking for a great all around tire (except the rain). I've tried NT-05's and R888's with not much luck(295's and 305's). I've since installed 2010 GS 18x9.5 & 19x12 so I'm looking for the 345 version of the R6. I'm not worried about tread wear as long as they hook up, from a dig on the street. I'm in to 0-60, like getting on the highway and such without spinning wildly.
Any info on these tire is greatly appreciated. Thanks....

I ran the NT-05's not the radials. They were hit or miss, it was almost like the more I ran them the less effective they became. I'm interested in the NT-05R's as long as the top end stability is there. Most radials are squirrely at highway speeds, especially in a curve. And thats why the R6's keep coming to the top the conversation, sticky+stable. My only concern is when they are not up to temp yet how slippery are they ??

I ran an A6 tire for a long time, its the same as an R6 but the rubber is "sticky" at a lower temperature, so it's good for street use over the R6 which will take some heating up before its ready.
275/35 a6s in 750whp mode (different car) I had full traction around 80 when they were new, and lower on good surfaces.
They aren't really THAT great at "hooking" from a low speed dig, mickey thompsons did better at that for me. But if you are starting from a roll they are excellent tires, they are good for keeping traction more then absorbing a sudden throttle input like drag radials can sometimes.

The A6/R6 tires are not meant to be a straight line tire. They are road course tires with the emphasis on cornering. I sometimes drive our Z06 to and from local Auto X events on the A6's and they do not hook any better then my PS2's in a straight line unless very warm. They will however out corner the PS2's even if they are fairly cold.

The R6 and A6 are great road course tires. The A6 gets up to temp a bit faster than the R6. The R6 takes a couple of laps before it sticks. The A6's wear a bit faster than the R6, but the road race trend is that the A6 is the preferred tire.
The Toyo 888's are a very good road course tire and have the added benefit of decent rain grooves so they can be run on the street easier than the Hoosiers. They still take a couple of laps to get up to temp. These tires also like a higher pressure than the Hoosier's. The 888's really grip well when warm with 41-43 tire pressures.
None of the tires mentioned are going to grip as well at the drag strip (as compared to the road course) as a drag radial will because they do not get heated up enough, but they will certainly be better than "street" tires.
Hope this helps!

So my next question would be is it the rubber compound or the tire design(that makes them different) ?? Why can't they come up with a tire that has a drag radial's bite from a dig but top end stability of the R6's or PSC ??
Or whats the closest thing to the best of both worlds ??

More sidewall & ET streets. I am currently running Nitto 555RIIs and switching to ET streets.

The Nitto NT-05R is avaliable in 345/30R19. With a 4" sidewall how stable are the guys saying this tire is, at speed. Or would you even notice ??
And do you guys think these will hold 625rwhp from a stop, on the street ?? Just some insight; 3.42, 2970lbs, 6speed, and the power adder is N2O. So she hits real hard

Yes, I'm looking for some great street tires that will laydown the power but will still handle well on the highway. About my torque level; N/A is 410ish at the wheel but at 4K it jumps to 670ish at the wheel, intantly 
. Of course I speaking about when I'm spraying her.

I run the R6's and they work well for me. They are a huge improvement over the pilot sports they replaced. I wish I had gotten 18's for the rear and may eventually. At 600 rwhp I can go wide open in 2nd, but thats off the bottle so with less tq than you're making. I'll try the NT-05R next.
Between the R6 and the NT05R, one has a tread wear of 40, the other 0. If you don't like one you'll get a chance to try the other soon enough.

This is all great feed back. Does anyone have first hand experiance with the NT-05R's ?? Traction compared to other DR's and how well they handle ?? We are all aware of the high speed handleing issues of DR's.
And also about the Hoosiers, from what I've read the A6's can get "heat soaked" quickly, so Im worried about them getting greasy on a road outing. And thats why I was leaning towards the R6's but they do take longer to put the heat in them. Which could be a little scary for the first part of the drive

.Alot of track driving is experimentation. Your driving style and track temps will have an impact on your tire temps since the tires are going to be heated by friction, track surface temperature and heat from the brakes.
Try starting at 30 lbs and make note of how the car handles and what the tire pressure are immediately after exiting the track. If the tires performed to your satifaction, try increasing the starting pressures until they get greasy. Make note of your findings and use the information for future reference.
It is important to note that different tire compounds perform best at different temps. For example, the Toyo 888's seem to prefer higher pressures and perform very well at 41-43 psi.
