The NT555 G2 is Nitto's next-generation Ultra High Performance Summer tire, developed for drivers of muscle cars, sports cars, performance coupes and sedans, seeking optimal dry and wet traction in a true grip-focused tire. Like all summer tires, the NT555 G2 is not intended to be driven, stored, or serviced in near- or below-freezing temperatures, through snow, or on ice.

The Nitto NT555 G2's silica-reinforced high stiffness compound is molded into a directional tread pattern, featuring large, tapered tread blocks for optimum dry grip. Two circumferential solid ribs at the tire's center provide rigidity for straight-line stability during hard braking and acceleration, while reinforced shoulder blocks offer satisfying grip and cornering in both dry and wet conditions. Four wide circumferential grooves allow water to flow through the tread to lateral notches for water evacuation and hydroplaning resistance.

The internal construction of the Nitto NT555 G2 consists of a two-ply polyester casing for flexibility and stability. Its two wide steel belts are reinforced by 2 nylon cap plies for added durability and high-speed support.

Note: Ultra High Performance Summer tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.

Flexing of the specialized rubber compounds used in Ultra High Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage. Tires exhibiting compound cracking must be replaced.

...We have even had an unexpected fair amount of rain here in the desert, and an unexpected pleasure is that these summer Nittos perform excellently in wet conditions.

I initially bought these tires because the camber on my car is out and my tires were burning through on the inside. I was tired of buying expensive tires that only lasted 20,000. Figured when these cheaper tires suffered the same fate I would just buy more. Turns out I love these tires. They are good to excellent in every category. We have even had an unexpected fair amount of rain here in the desert, and an unexpected pleasure is that these summer Nittos perform excellently in wet conditions.

...these tires grip a lot better in the rain than I expected. Was able to do a lot better in the rain on the highway than expected and was pretty much passing everyone with ease...

The 96 mustang gt doesn’t come factory with a whole lot of power so grip in acceleration or from a stop on most tires won’t break traction but I will say these tires grip a lot better in the rain than I expected. Was able to do a lot better in the rain on the highway than expected and was pretty much passing everyone with ease. I would assume having a car with more power would be a better test of its performance but I was mainly going for the aggressive look rather than grip. Over all I love the performance and look of the tires and would recommend them to anyone with a staggered setup. They sit flush with the wheels that I have on the rear and may stick out past the lip of the wheel itself just a tad and I believe I have 10.5” wide wheels on the rear. The tires were also delivered on time and together.

Customers overwhelmingly rate dry traction as excellent, with most scoring 9s and 10s. High marks highlight strong grip and responsive handling in dry conditions, aligning perfectly with its Ultra High Performance Summer design. A few 7-8s suggest minor variability, but overall performance impresses.

I’m very impressed with their performance in dry conditions. They provide excellent grip and feel stable even under aggressive driving. Treadwear has been better than expected for a tire in this performance category, which is a big plus.

As for wet traction, it’s about average—not bad, but nothing I’d rely on in heavy rain. Personally, I avoid driving in the rain with these.

...Dry grip is very good both on the strip and canyon carving.

These tires look mean, not to noisy on the highway, they handle pretty well in the rain given that they are a high performance summer tire. Dry grip is very good both on the strip and canyon carving.

...The Nitto's provide excellent ride quality and give greater driver's confidence (stability) compared to the Goodyear's...

Replaced factory equipped Goodyear Supercar 3 tires for a set of Nitto NT555 G2's. Have not "pushed" Nitto's to the limit or driven in the rain with them (Weekend Cruise / Show Car), but can say that there is a night and day difference between the different sets. The Nitto's provide excellent ride quality and give greater driver's confidence (stability) compared to the Goodyear's. Yes, I would recommend.

I went though 2 set of these tires... I feel for the price you will not find a beater tire as i did autocross on them at lest 1 time a month... I will note these tires are not competitive vs some of the new compounds out there. but for what they are they are a great tire a good mix of milage and performance...

I went though 2 set of these tires. They were my daily tire and autocross tire and track tire. I only had one set of rim so changing out tire was not passible I feel for the price you will not find a beater tire as i did autocross on them at lest 1 time a month. They held to the Texas heat very well went though 10 plus runs in 100 degree heat before them gating greasy would highly recommend to any one on a budget that enjoys spirited drive are autocross are even track.

I will note these tires are not competitive vs some of the new compounds out there. but for what they are they are a great tire a good mix of milage and performance. Nitto need to update the nt555 2.

looking at maybe getting them for my new ride. no long have my 2017 Golf R

...Tire wear has been much better than I anticipated. Ive had these tires on for 1 year and will be buying another set when its time.

I doubled the factory power on my car and was very worried about being able to keep traction especially from a stop. These tires do pretty decent and warm up quick. Ive held 160 mph+ for a few minutes plenty of times and it was smooth. They are above average in the rain for normal driving but cant cant hold traction under load to save its life. Tire wear has been much better than I anticipated. Ive had these tires on for 1 year and will be buying another set when its time.
