Okay, I'm wanting a new set of kicks since my 2nd - 3rd gear Automatic shift nearly made be go into the wall. I want to make use of the extra 17x 8" factory wheels. Anyone out there have experience with the NT01 or the 555R's and what did you think about them?

I think the NT01 is a softer stickier tire but made for road course. The 555R is a drag radial. They are not going to be as sure footed through curves. The sidewall is more flexable than the nt01. I run the 555R's and they are GREAT! They are relatively cheap also. Im running 245 45 17's on the rear for the 1/4 and pulled a 1.74 60' without a hint of them giving up. Im sure the NT01's are great but probably not optimal for drag racing so it depends on what you want to do.

Hey RJ, What did it end up in the 1/4 mile and approx how much RWHP or mods have you done? Thanks for the info on the 555r's . Who'd thought it would be so overwhelming to pick out tires?

With a DA of about 2300' I ran a 12.3 @ 111 the last time i went. 390 rwhp is what the dynojet said. That is with the 224 cam and stall only.

Svede, the NT05 and the NT05R's were my first choice, but I want to retain use of the stock rims 17x8. They just didnt offer them in a size that would work.Unless I go with a 235/40-17. What do you think about that? below is a link to the sizes offered. Svede, tell me what you think. I'm hoping to get the tire before the weekend and hit the track again.

The NT05Rs would wear off before you could go around the block :D. Even the street NT05s are only 200AA but at least that's a little better. I've seen people comment they get 15,000-20,000 miles out of NT05s as they are a soft grippy rubber.

I see they have 235 and 255 in 17s. 235 wouldn't be horrible as the guys with 18"s came with 235s stock unless you autocross or something. I carve the corners but push the limits of the tires more in a straight line.

I know I've been thinking of what I'd do next and I vacillate between max performance and getting decent wear. Unfortunately you can usually only pick one.

I have nt05r's on my Chevelle. I have maybe 5k miles and 30 track passes all in the 12.2-12.3 range, crappy 1.80 60ft because Of the slammed circle track springs, but my car makes 376whp and the only way I could spin the tires on a roll would be to slam 1-2 shift and it would only spin a few feet.

They are light years better than my old m/t drag radial.

Now remember the R is the drag radial, the nt05 is the street radial.

Either way I don't think you'd be disappointed.

How do you plan to drive the car? Thats how you pick your tire. 555R and NT01 are really made for different purposes.

Also, if your 2-3 shift is kicking out on the A4 then it sounds like you need to have your tune looked at and adjust the trans settings.

Jpalamar, I'm not convinced there is anything wrong with the tune or trans settings. The tires I have on the car now are junk. Nexen Wal-mart specials that came on the car. I'm gonna try the car with some good tires and see how it handles. I will mention what happened to the tuner just to be safe. I appreciate the input. The tires I'm looking for are just for track day.

They Fit

Okay, thanks for all the input from everyone. I ended up going with a 255/40-17 Nitto NT05 drag radial. They fit like a glove. Hopefully I can get to the track this weekend. I am also having the tuner soften up the shifts just a tad. Can't wait to see what she does!

Funny this should come up but after crawling under my car after this last week I decided I really need tires myself. Oddly enough my back tires are totally bald :D but the fronts are pretty worn too. I'm really leaning towards the NT05. If I get the 275s for the 9"x17" wheels I have to decide if the 255s will fit in the front or if the 235s will be too different a diameter for the ABS.
