Any feedback compared to the nt01 for street use?? Nt01 quieter?

 

The NT01s don't come to the correct size for the 991tts. If they did that would be th tire of choice for many, including myself.

 

 

I asked on the other forum and the track guys told me no. You have about .5 inch difference in diameter which is acceptable, but unfortunately it is backwards. The front Nittos are larger instead of the rear ones.

I have used the Nittos on my old 997.2 4s on 18s. The traction was ridiculous and road manners very decent when new. I wish Nittos produced more sizes.
