Imo the 555r2's are the best tire out there that offer the least amount of compromise.

Pros- Quiet, handle relatively well, no rear end wag at high speed, and night/day better traction vs any high performance street tire without giving up much tread life.

Cons- Not going to handle like a Super Car tire for high speed cornering.

I’m thinking these might be the ticket for street duty for the reasons you listed. Torn between those or the R888R.

Happy Thanksgiving gents. Keep these things on the pavement!

Same to you! Cheers!

Thanks King, great information. I kinda ruined the high speed cornering when I bumped to this stage 5, I definitely respect this power in the corners now, much more than I did when she was stock. Nittos prolly the way to go...

Honestly I wouldn't be surprised if the 555r2's hook better at higher speed then your drag pack with MT's. The MT's are probably the best there is at the track on a prepped surface but on the street they seem to do weird stuff...like act like they are hooked up then break loose. Also the street tears them up like a cheese shredder and when the tread starts to ball up they lose a lot of grip.

I wish Nitto made a 17" tire that was closer in size to the OD and Width of my stock tire/wheel combo...

[KingLT1]

Yea the only thing some what close to those specs is their 345/30/19 which should fit your stock wheels.

So, now running Mickey Thompson Street ET SS's 325/30R19. Still struggling to get traction from a dig and at highway speeds when applying power the ass ends tends to sway back and forth. Wondering if the softer sidewall is causing this instability...

So now what, Nitto 555R2? Michelin Pilot Sport Cup 2's to maintain the highway stability?

Smaller wheels with a larger tire to gain some sidewall flex? Any concerns with this combo yielding similar highway instability issues?

Yeah, I won't run ET Streets on the street. R888R or NT555R2 are much more stable IMO. My Smoothboost electronic boost controller made street use so much better too. You can dial it back for street use at the turn of a dial or crank it back up the track. Just something to think about.

I see they make one for the Magnason line as well, did you install this yourself? Does anything have to happen to your tune for this controller to work?

No, I had the shop I use put it in. Didn’t look bad though. Actuator is cake to mount in place of the vacuum one. We mounted the control box under the dash, going through the grommet where the air tube used to be (or at least I thought that was the plan lol). They bent up a small bracket to put the boost dial in the glovebox since I wanted to keep the interior uncluttered. I have not made any tuning changes for the Smoothboost and don’t feel I will need to since you don’t need to retune turning the boost down, it’s usually if you go up past where you were last tuned at. I’ll have my tuner double check it when I see him on 7/11.
