Tires are designed specifically for different vehicles and wheel sizes. Tell us about your vehicle or the specific size you want so we can help find the right tires for you.

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.

Toyo Reviews

Feedback consistently shows the Toyo Celsius II delivers excellent comfort with smooth ride quality and low noise levels. Treadwear receives strong praise (8-10 range), though some note earlier-than-expected wear. Winter traction stands out with confident performance in snow and slush, supported by reliable wet grip and hydroplaning resistance. Dry handling is responsive, fitting its grand touring role. While most categories score highly, a few reports of uneven treadwear suggest monitoring alignment and rotation practices for optimal longevity.

...Giving these a shot, I've not had any issues with dry, wet, or snow handling... Steering is good in the winter and the tires overall feel very predictable in inclement weather...

I grew up with my parent's always buying Toyo tires for their vehicles. Dad always purchased Toyo M-55s for his truck and my Mom always had a variant of the Toyo Open Country ATs on her Suburban. We never had any wear issues or compromises from these tires so I figured I'd try the Celsius II on my Mazda CX50. Tires are expensive for the 20" wheels that come on these and while I've previously purchased Michelin CCs for my other vehicles, I couldn't stomach over $300 a tire. Giving these a shot, I've not had any issues with dry, wet, or snow handling. We get a lot less snow in my area than we used to so a decent set of all weather tires with AWD is more than enough to get me through the handful of snowy and icy days. I feel these tires do well on ice and I never had any issues in deep, slushy snow. Light snow it's like the snow isn't there. Steering is good in the winter too and the tires overall feel very predictable in inclement weather. Road noise is somewhere in the middle of a little noisy and not too bad. Overall, happy with my choice. At 10,000 miles all tires have roughly 8-9/32nds of tread remaining.

...The tires handle and maintain traction well under wet conditions...

I picked this tire when my wife's Audi A3 convertible needed new tires and she's very happy with them for highway trips and errands. The tires are very quiet. They make her feel secure because the tires grip well while turning and when braking. The tires handle and maintain traction well under wet conditions. They're a good value as well. These tires have impressed us to the point that I will buy the same tire (or the sport version) for my VW when I need new all-season tires.

...performed better on snow and ice than my last set of dedicated snow tires...

These tires are unreal!
Purchased these tires prior to winter as they were said to be good on snow and ice. I was tired of switching between all-seasons and snows every year. So far these tires have performed better on snow and ice than my last set of dedicated snow tires. If treadware holds up these will be my go to tire for everything going forward.

...Amazing traction in light to medium snow. It's nearly as good as a dedicated snow tire. The tires feel grippy and predictable when sliding in snow, not scary at all...

Biggest pro: Amazing traction in light to medium snow. It’s nearly as good as a dedicated snow tire. The tires feel grippy and predictable when sliding in snow, not scary at all. They do well on wet roads too. Perfect year-round tire here in Utah. It’ll make your 2WD car outperform any AWD car equipped with regular all-seasons.

Biggest con: the soft compound combined with the tall tread blocks (like 12/32”) hurt the dry handling characteristics a bit. Quick steering inputs feel a bit numb. The tire squirms a lot when cornering aggressively. But this gets better over time as the tread blocks wear down and get shorter. This is to be expected though, out of this type of tire.

...I have driven on them in dry conditions, and they have performed well in those situations too...

Bought these tires in October in preparation for driving in cold, long, snowy, Wisconsin winters. I drive a SS Camaro in the summer and store it in winter. I got these tires for the 98 Buick I had just bought as my winter driver. These tires have performed very well in all of the snow we have gotten so far this year. I have driven on them in dry conditions, and they have also performed well in those situations too. There is a bit of tire harmonics that are not as quiet as I would prefer, but it is not over whelming. As far as tire wear goes, I have not put enough miles on them to determine how well they will do in that category. Overall, I would recommend these tires, especially for the price, to anyone who asked me.

...I had these tires on a Subaru Legacy sedan, and it plowed through any weather conditions.

This tire is a game changer because I use them year round, so no need to store and swap tires every six months in NE Ohio. Best part is, the traction on snow and ice does not deminish as the tread wears. I had these tires on a Subaru Legacy sedan, and it plowed through any weather conditions.

...The ones I have on now are significantly quieter and more comfortable than the stock tires...

I wasn't certain how I wanted to rate these. All I can say is, these All-Weather tires are far better in the winter than your regular All-Seasons and they can stay on your car all year. I bought the same tires for another car I had many years ago. The ones I have on now are significantly quieter and more comfortable than the stock tires. You do sacrifice some tread life, and they're not as good as dedicated winter tires in the winter, but they work really well, and you don't have to change them out at the end of the season. Minnesota has extreme temperature fluctuations in the winter so having tires that work well on either an icy winter's day or a warm winter's day is nice to have.

excellent traction under all conditions, particularly in the cold with a tradeoff for noise. The carcass isn't afraid to resonate and hum to road defects, it's noticeable but not objectionable. On smooth roads, the tread noise is subdued (but not silent) to match. Ride is controlled but sidewalls are on the soft side when it comes to steering response and rebound under cornering. It's a balanced all-season snow-performing tourer.
