I'm currently running Nitto NT05R Drag radials on the streets, and I'm not really happy with the traction I get with them. In my car, you really have to do a full burn-out to get them to heat-up before I can get the needed traction to hook in 2nd gear.

I need a sticky tire that I don't need to heat up as much. I'm not concerned with wear. I run 60-120+ a lot, so I need the traction on the streets.

Before, I get a 1000 comments that say, these are race tires made for the race track, blah, blah, blah...I know. But, I have tried all "street tires" and I need more traction.

I won't be running them much...no rain, etc. I'm looking for traction on the streets. I'm making a true 620hp+ at the wheels.

Any helpful comments are welcome about running Hoosier's A6 345/30-19's on the streets.

Thanks, DB

how are the nt05r's up top? like the stability? any sway?

I don't think an autocross tire is going to be what you want. They do get better traction at lower tire temps (130s) but they may not be able to handle the torque you apply to them on a shift from first to second at WOT at max rpm. With a stock car I have trouble getting sticky tires to hook up on a shift from first to second on the second lap (tires warm) of a run on a Go Kart track with a 200 ft straight if I run up close to the rev limiter. Even had trouble doing this with a stock C5 Z06.

Not great for stability. You have to run low tire pressures for them to work better off the line, plus the sidewalls are softer. I would not push them over 150.

LS9Drew

Well like how you say you do alot of 60-120 pulls does it feel fine up to that fast? And driving on the freeway does it ever feel like it will come out from you very easy? I know the sidewalls are softer than a typical tire but they are suppose to be better than other DR's

I have run R6's daily. I make 594rwhp all motor. From 60mph that will put you in second gear. The R6 will hold that with ease. The A6 will be even better. Frequently do 40 from first gear to 170-180 on the R6 no big problems. I have raced on NOS making 700rwhp and hooked fairly well, may get some wheelspin but it will then hook. The A6 I suspect will hook great on that situation. If I use progressive control it will hook with ease from second gear.

DaddyBarlow

Good info. What sizes do you run up front and rear?

For what I want to do, do you think the A6 is better choice for me than the R6? I'm in Michigan.

DaddyBarlow

Yes, I think they are fine up to those speeds. They feel a little unstable if you switching lanes a lot at high speeds. But, I do think they are fine up to 140 or so. They don't feel like you are going lose control...unless you break them loose under power at 80mph, like I do...lol.

Overall, I think they are fine tire. But the compound is not soft enough for my car...unless you heat them up (burn-outs). On hot days, the traction is also pretty good. Living in Cali, I think you should be good.

And they will get you home in light rain (at least when they are new).

Thanks for the info!

I also have the Hoosier R6 and 600RWHP all motor. I can go wide open in second gear without spinning. I have a C5 with 3.73 rear gears, so with a 3.42 you should hook even better. I had planned to try the NT05R next, maybe I'll consider the A6. I'm running 345s in the rear and 275s up front.

DaddyBarlow

Good info! I think the A6 tire should be better for the cooler temps here.

Black_Mamba

295 fronts 345 rears. R6 all corners.

A6 is a better choice for what you want IMO.

0Anthony @ LGMotorsports

I would say for what you are wanting the A6 is a better tire hands down. Doesn't take hardly any temp to get them to hook at all.

Now the only downside from this is that the more you drive on them, the more they are going to work harden so if you put a lot of miles and time on them and a lot of heat cycles they are going to probably wear out quicker grip wise before they wear out tread wise. That is true of any race tire though.

What's the difference between A6 and R6? The specs look identical.

I am really interested in all this too cause my car came with NT-05s which I though were fantastic in stock form but now my car has 563/472 on a mustang dyno so Im thinkin that they are not going to work near as well.

The Hoosiers look and sound awesome but in looking at them I would just worry about getting stuck on a trip in the rain. In which case they look not soo good I may have to stick with the NT-05s and try the NT-05Rs that at least have some water channeling.

Thank you for the info guys!!

0Anthony @ LGMotorsports

As far as lap times go, on a 1.7 to 2 mile road course the A6 will be roughly 1 second quicker given all other specs the same, but will fall off quicker and wear out quicker.

Little story/anecdote... Track day, Solo1, drove 44 miles to and from track. I had the R6 all four corners. On the way back home a huge torrential rain pours. I was scared ******** at first. Slowed down to a 30mph crawl at the most. Surprisingly the car behaved very well. I had time to recall how badly, and with less water on the road, the MH racemaster DR on my old Supra hydroplaned at 15-20mph even with all the lines cut into it. Thing is. Friend of mine on another Z06 did same drive but he had two INVO up front and two NT05R rears, obviously he was not there to race. Guess who did not make it home in one piece and now has a new vette?

I know there are many other variables at play and that luck may in fact be involved. Point is, don't judge a book by it's cover. The number of grooves or lack thereof may not be the greatest indicator as to ultimate safety or performance.

VetteVinnie

Your friend's problem can easily be attributed to the fact that the Invos channel water very well and have decent wet traction and the NT-05Rs don't. Thus, see here:

Never a good idea to mix tire types. Unpredictable handling can result.

BlackMamba,

How long do these tires last? I don't daily drive my car and I found out this last weekend that I really need sticky tires. I was looking at the MT DR but haven't read anything about them. The A6 may grip better but the R6 will last a longer. Is that a correct statement? I don't drive in the rain either and won't DD my car either. Just a weekend toy.

I was planning on getting the INVO's up front and a DR out back, but after reading that, I'll be going with the same tire in all 4 corners.

LS9Drew

just get NT05 up front and NT05R outback
