The 555R has a tread wear rating of 100..and only 5/32" of initial tread depth. On paper, it's supposed to be good for 10K miles. Folks around town see typ 10K...and several get 15K, but that's very minimal strip use. If you spend 2 full days at the strip, they are done.
The NT-05R has a tread wear rating of zero ! 6.3 / 32" of initial tread depth. Not wet friendly.
if you are getting 17K miles from them, then why switch ? How many miles a year do you put on the car ??

When I ran them I got almost 17K miles. No track use. Have a set for the strip.
