Both tires are mainly designed for use in competition on race, drag, street, or dirt tracks in the summer season. Both contenders have a directional tread pattern. Both contenders are best suited for high-performance sports cars.
Comp 2 is equipped with the features of silica-infused racing technology, the internal structure of the performance racing core, and a high-performance sport tread design. And due to these features, it is superior in the dry pavement grip, produces less noise, and is also a very economical tire.
The unique features of NT555 are its wider circumferential grooves, reinforced shoulder tread blocks, and high stiffness of silica compounds. The benefits of these features are described as follows.
- It has a superior grip on wet pavements.
- It has the most reliable handling on dry and wet paths.
- It possesses supremacy in the factor of hydroplaning resistivity.
- It is more durable, fuel-efficient, and comfortable than its competitor. And thus, it is slightly expensive too.
Compared to Sport Comp 2, NT555 has superior handling performance, better wet grip, enhanced hydroplaning resistivity, higher durability & fuel efficiency, and provides a more comfortable journey. But lacks behind its competitor when it comes to dry grip, noise production, and cost.

Tread Design
Comp 2 has a directional tread pattern with four circumferential grooves and three ribs; one in the center and two are g-Hook intermediate ribs. The central rib is sliced with a longitudinal sipe. There are g-Hook intermediate grooves inside the g-Hook intermediate ribs providing biting edges for a firm grip. There are no notches and siping patterns all over the surface of Comp 2. All of these grooves have varied width, which means it has a slightly inconsistent contact patch. But overall its contact patch is comparatively more than its competitor because it has relatively narrower circumferential grooves. Likewise, it has comparatively narrower shoulder blocks.
G2 also comes with a directional tread pattern but with five circumferential grooves and four ribs. It also has an inconsistent contact patch because of the varied width of all grooves. But overall its contact patch is comparatively lesser because it has relatively wider circumferential grooves. Its central twin ribs are not having any notches or sipes. But its adjacent ribs have sipes of moderate depth and narrower lateral grooves. Its shoulder blocks and shoulder grooves are wider than its competitor. And there are also slight notches on shoulder lugs.
Road Grip
Comp 2 has a comparatively more contact patch. So its grip on dry pavements would be better than its competitor. There is only one longitudinal sipe on it which is not enough for Comp 2 to have a better grip on wet roads.
Similarly, G2 would give a comparatively inferior grip on dry pavements because of having a comparatively less contact patch. But on wet roads, it would have a comparatively better-wet grip because of the lengthy siping pattern on its adjacent ribs.
| Parameters | Comp 2 | NT555 |
| Dry Grip | High | Moderate |
| Wet Grip | Low | High |
Road Handling
Comp 2 has comparatively shorter shoulder lugs which give its drivers an inferior handling experience on dry roads. And it will also provide a relatively inferior handling on wet paths. Because it has relatively narrower lateral grooves on its shoulders compared to its rival.
NT555 has comparatively large shoulder blocks which enable it to provide superior handling on dry roads. It would also give superior handling ability on wet roads because it has wider lateral grooves and slight notches on its shoulder blocks as well.
| Parameters | Comp 2 | NT555 |
| Dry handling | Moderate | Higher |
| Wet handling | Moderate | Higher |
Hydroplaning Resistivity
NT555 has higher void ratio and therefore it provides more space for the water to pass, the water is thrown backwards and tire can easily move forward without slipping. Comp 2 has a relatively lower void ratio so it isn’t able to beat its competitor as narrower grooves allow lower volume of water to pass from them.
Durability and Tread Wear
Both tires are made from durable material and provide a longer tread life. The major parameter to consider while comparing their durability is tread depth. Since the tread depth of NT555 is more than its competitor, we can state that it would last longer than its competitor. As due to deep tread it will take longer time to level up with the grooves. And thus, it is going to be a better choice in terms of durability.
| Contenders | Tread wear rating | Tread depth |
| Comp 2 | 340 AA A | 9/32” |
| NT555 | 320 AA A | 11/32” |
Comfort and Noise
For evaluating better comfort factors we need to analyze which of these contenders has more tread depth as it will provide more cushion on bumpy roads. So we can say that NT555 will lead in this competition due to having more tread depth than its competitor.
Noise is mostly produced because of having a high void ratio. More groove space can allow more air particles to be encapsulated, they would collide inside the grooves at high-speed driving which will result in more noise factor. Comp 2 will lead in this sector because it has relatively lesser void ratio than its competitor.
Hence, NT555 would provide comfort but at the cost of more noise during high-speed driving.
Rolling Resistance and Fuel Efficiency
Fuel efficiency is linked with lesser rolling resistance. And rolling resistance is directly proportional to the amount of the contact patch.
NT555 has a less contact patch as compared to its competitor. So it would be a more fuel-efficient tire and the winner in this competition.
Load and Speed
Comp 2 (245/45R20) has 726 revolutions per mile. It became 168 miles per hour when calculated. This means its speed lies in the W rating. And its load index is 103. Which means it can carry 1930 pounds ideally.
G2 (245/45R20) has 725 revolutions per mile. Hence its speed lies in the W category with a maximum of 168 miles per hour. It can carry 1929 pounds at max as it also lies in the 103 load index category.
Both competitors are tied in this competition since their load-carrying capacity and maximum speed rating are equivalent.
| Contenders | Speed Rating | Max Speed (mph) | Load Index | Max Load (lbs.) |
| Comp 2 | W | 168 | 103 | 1929 |
| NT555 | W | 168 | 103 | 1929 |
Price
Due to the fact that NT555 has superior wet grip, better handling on dry and wet roads, enhanced hydroplaning resistivity, and better fuel efficiency, it is relatively costlier than its competitor. The prices of Comp 2 (245/45R20) and NT555 (245/45R20) are $190.79 and $211 respectively.
