My friend that owned the 07 in my avatar before me had 555s on the car for awhile. I drove it at one wet & cool track day, they were terrible ... no traction for turn-in or corner exit.
NT-555's..and 555 G2's are summer use only. Traction drops when temps drop. I only use mine from end of april /may to end of oct.
Then use Nitto motivo's for the fall /winter on oem rims, good rain tire..semi useless in snow.
The new G2's are a lot better in the wet vs the older 555 ( 5 rain grooves vs 3). But they were never intended for road course use. 555 / 555-G2 is just a cheaper version of a 300 tread wear tire vs a MPSS in the same 300 tread wear rating.
