Nitto NT01 305/35 R18 Toyota Aristo V300 6,000 miles September 18, 2024
Dry grip: handles 750nm torque on an almost 2-ton car very well. Sometimes a light spin in first gear. Still, it is not the fastest nor the grippiest semi-slick tire.
Wet grip: drizzle is fine, light rain is okay (just be smart about it), anything more and it’s skating on ice.
Road Noise: on par with others in the category.
Wear: this is the best part; it doesn’t. You can expect 16x 15-minute sessions when rotated on a square setup.
Handling: not the best communicator, but warnings are audible and traction does break predictably.

Pros: wears like iron, has good dry grip even down to 15C, but not so good where you get away with bad driving. Cons: hydroplanes on standing water, is a bit noisy, One of the best values in track day tires that can be driven on the street.
