Nitto NT 555R review
I wanted to post my experience with my new nitto nt555r drag radials so others might get the same benefit. Long story short i went to lucas oil last night and disappointed myself in racing, but i haven't done it in years, and never in a stick car. On to the nittos- First i will say i screwed up in my rim choice by not getting a little wider rim ( drag 7.5) but whats done is done. I purchased the rims and Nitto 245-45-17's for my sportline equipped 09 tc, after checking with others, got them through discount tire direct, heat cycled. I can say the 17" drag rims cleared the front brembo's with no issues. I also had no clearance ( or rubbing ) issues with the tires, they are taller by about an inch then my 225 V12 evo's.
First time out yesterday on the street, was the first time i have gotten traction for any length of time in 2nd. I am fully bolted and trifecta tuned to 25psi. I shifted to second, got the revs to 3,000 and eased into full boost with just chirping only, and it was awesome. I stopped and gave it hell from about 2,000 in 1st, and it only spun for just a bit before biting and going, never been able to do that. At the track after bypassing the water box and doing a short burnout, they hooked right out of the gate. I cant say enough about the grip, and it was fun driving around knowing i could actually get traction if i wanted. I put approx 80 miles on them yesterday with no visible signs of wear, but know they wont last long term if i ran them everyday. They are very sticky after heating up, and will pick up small stones easily, so stay off of newly sealed roads. With the rims being a little narrow it did hunt around a little on the top end at the track, but no worse than i had experienced before with slicks. Hope this helps someone. Posting a couple of pics.

Never wanted slicks as i don't want to have to deal with taking them off and on at the track. Don't have a zfr so i really don't need them. I have a set for the nova, as it does need them, but not the Cobalt. The cobalt is my DD and i have to keep it that way. If i went with slicks, it would make me want to put a bigger turbo on, due to being able to get traction, and that's too tempting.

Yeah, its home to the U.S. Nationals. Honestly i have actually seen people get out of their cars at the starting line, and stick their shoe to the track, and pull their foot right out of it. Its usually pretty sticky, but not as much as when im going full boost in 2nd gear, thats why i got them. Not for starting line so much, unless the track is cold.

Sure they do there are quite a few people on here running m&H 17 in slicks and they fit over the brembos also. I got mine from Buschur racing After a cpl people on here said they worked well for them. They made them for evo they have same problem with brakes being to big for 15's and 16 in rims. They also have m&h drag radials I would not mind trying also. They fit nicely on a 7.5 in 17 in rim I wouldn't really try on a 7" wheel though would bulge I bet.

In the past, many racers tried to “heat cycle” their own tires with mixed results. In addition to the inconsistency, there was the inconvenience of mounting and dismounting the tires before using them to race (after the first heat cycle, a competition tire must be rested 24 to 48 hours to reform the molecular bonds).

Interesting post /\
Just chirping in to say i just got my nt555s put on about a week ago and they are really good tires. They dont hook in first gear that good but better than my last. They corner nicely and the tread is pretty soft feeling

A competition tire is built with a highly sophisticated tread compound. This compound is capable of sustaining traction throughout a much wider temperature range, but is also extremely sensitive to the first heat cycle of its use. During this cycle, if controlled precisely, the tread compound stretches as it heats, breaking the weaker, shorter molecular bonds within the rubber. The benefit of this process is a tread compound that lasts longer and provides better traction. However, if the first cycle is not performed correctly, the tread may develop irregular compounding, leading to poor wear and inconsistent traction.

As far as the NT01's, im sure they are a good tire, but their primary design is for road racing. The biggest differences in them that i saw were the sidewall is stiffer ( for cornering) and the tread on them really isn't designed for rain. I wanted something i could bolton at home, drive to the track, and could make it home in light rain, if needed. The 555r's wouldn't be the best tire for a wet road, but they would get me home. The 01's i would be afraid of in wet conditions.
