I'm running the Ad08R and love them. HIGHLY recommend. I drive mine around 5000/year and they've lasted almost 4 years now. The inner edge of the fronts is just now worn smooth so I'm about to replace those. The backs still have some life left. Amazing wear for a 140 tire wear rating! They stick like GLUE, assuming it's above 70 degrees. Below that the grip dies down drastically. I run a 235/35 and 275/30

FYI: Wet grip is good, but I don't drive it in the wet anyways. Dry grip was my focus for buying. They're predictable and hard to break loose if it's hot out.

I've run these street and autocross and they're just awesome grip

I don't think you could go wrong with the RE11A or the AD08R. Both are great for dual use. The RE11A is better in the wet (grip and hydroplane resistance) and is quieter while the AD08R has a tad more dry grip at the limit. Both are predictable and provide audible feedback. The NT05 is a step below these tires, it compromises wet and dry grip and will wear faster, in my experience. Also I feel like the NT05 grip drops off a lot quicker with wear. The main benefit of the NT05 is that it can be found cheaper. I currently run RE11As as my dual use tire FYI, it is currently my favorite since it performs so well as a DD tire, has awesome wear and I don't have to deal with as many of those "sketchy" moments in the rain. The only other tires I would recommend for dual use is the RS4 or Falken RT615K+ but those do not come in sizes you need.

^ Not trying to derail the thread, but could you tell us more about the RT615K+? I seem to remember the original RT615 wasn't that great, and I didn't think the K improved it all that much. Haven't heard much about the K+. I still have fond memories of the old 215, it seemed like all of the bigger manufacturers were blindsided by that tire.

I had the same feeling as you, I felt like the RT615 was an "old in the tooth" tire and just meh, but then my friend who races in similar endurance races and recently was rookie of the year in Pirelli world challenge (not to name drop) said he was highly impressed with the K+. This guy is my mentor on car dynamics and is a way better driver so I gave them a try on my 240sx for my 2 day race at Road Atlanta. Keep in mind my first 2 hours in the car was in icy and snowy conditions. I found the tire to be extremely forgivable with moderate to good grip. What really surprised me was the grip in the wet/cold, especially braking down hill, even in the dry. My previous tire, BFG Rivals, would lock up all the time in similar situations . Also the wear was outstanding, after 5 relatively fast drivers, 2 days of varying weather, no ABS or TC and approx 18 hours, I still have enough tread to probably do another full race. Is it the best tire I have every tried, no, that goes to the RS3 but for the price it can't be beat. Since I never tried it on a DD I can't fully give feedback on that experience other than to say it's handling of non ideal weather was acceptable.

Not sure about the others, but I ran NT05's for quite sometime until I switched to Venuts RS3's and never looked back at Nitto's. NT05's weren't that bad to be honest, the longevity of the tire was great and if the weather was right all was perfect, once it started to drizzle/rain they performed worse than RS3's.

I have since switched to R888's, awesome grip, but man what a sucky treadwear (not taking anything away from the weight of ISF). I started avoiding short configuration tracks as last time I went through brand new R888's in one day, but I'm still sticking to that rubber at least for this season.

I use NT05s on my Corvette track car. They're cheap, durable, and reasonably fast. One thing I like about them is that they tend to make noise progressively as they approach the point of breaking away; NT01s are pretty quiet, by the time they're making noise, they've lost traction. NT05s, especially in big sizes (I run 315 square), are sketchy in the rain (not a concern in Southern California). If I wasn't driving 100 miles each way to the track, I'd go with something stickier, but these strike a good balance of wear and performance.

I ran the RE11 last year (on Piston1047's recommendation), and I think they're a fine dual duty tire. The wear rate was impressive. After 8 months of near daily driving, and 6 track days, they still had quite a bit of life in them (see pics here). I don't drive in the rain much, but the few times I did, they felt as stable as the Michelin PSS did. For me, the only downside was the really stiff sidewall, which made them a bit harsh on rough/bumpy roads.
