Default Nitto RIIs

I read several interesting post when I did a search on the Nitto RIIs. I didn't realy see any direct comparisons to the Goodyear GS-D3s
I have an A4 with a little over 400hp and a SY3500. I presently have Kumhos and am thinking of going to the Nittos 555RIIs. I have basically no traction off the line now, so I thought the RIIs might do a little better.
The problem is, I drive the car on long trips occasionally, and I don't want to give up the handling. Because of that I have been also looking at the Goodyears. Some say the dry traction is just as good, but the wet weather and handling is better. (The price is pretty close)
I also read in my search, that the Nittos only hook good after they're "warmed up", which you don't always have time to do if you know what I mean.
Am I making a mistake with the Nittos? Should I just go with a full thread tire like the GSD3s?
Thanks

Wrong choice of tire, you want the original "R", the drag radial. The RII has a stiff sidewall to hold corners.

Also, they may call it a "drag radial" but I don't agree. It is basically a soft compound radial (street tire). On the street it will act like a real good radial, but if you heat them up it can stick like a drag tire.

Compared to the other drag radials, it is the best on the street but the worst with traction. Compared to other street tires, it is worse on the street (but I like them, there are no problems running them), but the best in terms of traction. I consider it a middle of the road tire that is decent in all areas. The things they don't do well are hard cornering (sidewall flex) and rain when the tread is low.

But they are no Mickey Thompson.

I may have to reconsider my direction with tires then. I don't want to sacrifice any handling ability. I picked the RIIs because they were supposed to give improved traction over a regular radial, while giving great corning ability. The DR had been discribed as "loose" because of their soft sidewall, and that is definitly not what I'm after.
I love to take the car to the mountains for some spirited driving, and use every on ramp as an excuse to test my driving skills. I rarely visit the drag strip (80 miles away) but need great straight line traction VERY often.
I may have to consider the Goodyears after all

You may then, because as you said the R can be a little soft. I run mine at 25psi for best wear, and I can feel it when I corner. I was told the RII is going to be harsh on the street (more so than a normal tire) because of the stiff construction.

Not true in my case. I've been running the RII's in the back for awhile now. I hook good from a stop (At most, I'll chirp the tires) and I didn't have to sacrifice any handling either. Having the RIIs in the back feels like I'm running any other street tire. I personally think the RII is an awesome tire.

That's great to hear Redline.
I wouldn't really expect any of these tires to ride too smooth; after all, with a 35 aspect ratio and performance suspension, mine doesn't ride too smooth over rough roads now.
I realize there are very few tires that will provide everything in one package, so my priorties are;
Great dry traction
Great handling
I'm not as concerned with;
Great wet weather handling (I don't want dangerous though!!)
Long life

They would probably affect your ride more if they were on the front.

Also how are you only chirping the tires? With your mods you should be annihilating them. At least I do, with a similar car, on the 555R's. I can light em up just hitting the gas.

The biggest reason? Im a mile high above sea level. I'm sure if I lived in better air I wouldn't have a problem lighting them up. I also should have mentioned they hook after warming the tires up. I'll get some pretty good tire spin from a stop if they're cold.

I tend to forget I live in CO and others have a lot more power than me lol. I should have specified that.

As for wet traction, I've never had a problem with that either. I'm also very careful driving in the rain, regardless of the tires I have on but I have never had the car come out from under me unexpectedly.

Then to summarize the original question, how will they compare in straight line accereration WITHOUT WARMING THEM UP (read; burn out) to the 295 Kumhos I have now, and the Goodyear GS-D3?

Hmmm...I've never had the Kumhos or goodyears but I can say I completely destroy the street tires i have used, IE: I fishtail like a mother regardless of launch techniques, where the RIIs will spin but its not nerely as bad. When I launch on the street I just don't go ***** out with the RIIs like I would on the track.

You also have to keep in mind your 400hp isnt going to be easy to tame. A GS-D3 isnt going to give you anymore traction than a drag radial at those power levels. Regardless of tire choice you're going to have to sacrifice something. For ME, the RII is an excellent tire choice, for you you're probably going to encounter traction problems unless you run a stickier tire than both. At that point you're going to sacrifice handling.

Thanks for the input; That's the type of feedback I had gotten in the past. Nothing short of a warmed up slick is going to eliminate all tire spin, I'm just looking for somthing to "control it" without sacrificing handling or dependability (Call me greedy) Personally, I've always considered a little spin desirable. The tire spin is the "fusable link" that keeps things from breaking
The 295 Kumhos were a decent tire before my latest round of mods. I had prefected a launch technique of loading against the brake, then "driving" off of the line and easing in hard on the throttle to control spin. With the latest mods, however, I just can't keep from loosing traction. The 0-60mph times with my G-tech pro, are worse now than they were with less power.
I may have to give the RIIs a try. If I don't like them, I guess you will see them in the For Sale section
Thanks

Without warming them up, again, its like a soft street tire. They don't hook, but will do better than just about any street tire.
