Higher is better. The Relative Score follows your weights below; category scores do not change.
Weight the categories that matter to you
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Proxes R888R
Not enough owner reviews yet to extract themes.
Tire B NT555 G2
Pros
- Aggressive, visually appealing tread pattern and sidewall design
- Exceptional value and lower price point compared to premium brands like Michelin or Pirelli
- Long-lasting tread life and slow wear rates for a summer performance tire
Cons
- Poor wet-weather traction, with multiple users reporting hydroplaning and a slippery feel in the rain
- Lack of straight-line traction and wheel spin under heavy acceleration, especially on high-horsepower RWD vehicles
- Subpar performance in cooler temperatures or cold conditions, requiring heat to grip properly

Nitto NT555 G2
Owners praise the NT555 G2 for its low price, quiet and smooth ride, good dry grip for street use, and long tread life (often 20k–50k+ miles). Many others report weak performance in cold and wet conditions, poor traction off the line on powerful cars (easy wheelspin), and flat-spotting after sitting. Some report quality issues such as balance problems, cracking and belt failure. It is often judged a budget or mid-tier performance tire that falls short of Michelin PS4S and Continental alternatives.
“I can't compare Nitto to Conti directly. I replaced my OEM GY supercars with NT555 G2. Here's what I see: Above say 60 degrees, tires warm, Nittos lose probably 15-20% of the grip of the GYs. 40-60 degrees, tires warm, the Nittos start to equal out the GY's as you get closer to 40. Below 40 degrees, Nittos grip better, without question, mostly because it gets hard to get enough heat in the GYs unless you drive like an idiot. Below 30 degrees the GY's are hockey pucks, don't even try it. Just my unscientific observation. Your mileage may vary. I will say going from the runflat GYs to the Nittos was a great improvement in harshness of ride. I only have a few thousand miles on them so I can't speak to longevity, but anything has to be better than the GY's in that area. If someone can compare Contis to GYs, it should tell you the rest of the story.”
“I bought some because they are one of the few available in 315/35R17. At first I didn't like them, too easy to spin and the back end kicked to the left. Then I discovered they worked great at 38psi. I've never had problems with flat spots even after setting for several months. I would buy them again.”
“Staggered tire recommendations? Title. I have 17x9 rims up front and 17x10.5 rims in the rear. Currently running 245/45R17 on the front and 275/40R17 in the rear. Ideally I’d like to keep these tire sizes. Tires all around are Nitto NT555 G2 tires, and I’m just not happy at all with the grip. They’re fine around corners, but if I even breathe on the throttle at all in 1st gear, I’m instantly spinning. It’s sketchy as fuck in the rain, too. I wanted Continental DWS06 tires, but they don’t make those in a 275/40R17 for my rear tires. I’d only be able to get the fronts. Thinking about Michelin Pilot Sport A/S 4s, but not sure. I want to be able to handle well enough around corners, handle Ohio weather no matter what it’s doing, and I wanna be able to floor it in 1st gear and get very little wheel spin. Obviously not trying to drive the car in snow, it’s still mostly gonna see nice weather and occasional rain, I usually like to store the car over the winter and drive something else. But still, Ohio is Ohio, and our weather can absolutely never make up its damn mind. So, I come asking for tire recommendations. Don’t really mind price all too much, but my car is completely stock engine wise minus the exhaust, so it’s not like I’m pushing crazy power. I “daily” this car whenever the weather is nice, so I just need a streetable all season tire that won’t lose grip instantly whenever I try having a little fun. Thanks!”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
