The Most Durable Sport Touring Tires: 100% Italian Gran Turismo (GT)
It is an ideal tire for riders who use their own vehicle for long distance touring with side bags or tandem riding, in order to require wet safety and long distance stability.
It evolved the previous Angel ST and extended the concept to Gran Turismo. Even over long distances, its sporty character does not change in a wide range of usage environments.
It is in a sport touring tire and has set a whole new endurance standard.
Extremely good wet performance and grip.
As in PIRELLI DNA, it has the highest level of handling ability.
Demonstrates stable performance. Until the end of the tire life.
It is made by the bi-compound method (using two different compounds).

The Ultimate Gran Turismo

•From [ST (Sport Touring)] to [GT (Gran Turismo)]
In Europe and the United States, a large trip with long-distance travel, such as an image of [Transcontinental] or [Over the Alps], is called [Gran Turismo].

•Technical Explanation
1-1) Adoption of the new profile
[ANGEL GT] has newly adopted [Round Shape] at the tire center. [Round Shape] provides excellent straight-line stability, while reducing the difference in reduction with the shoulder and minimizing the performance change during wear. In addition, the edge of the tire has a shape that secures a bank angle of +5% compared to the ANGEL ST, and while adopting [Round Shape] at the center, it achieves [Sporty Handling] that is a feature of PIRELLI tires.

1-2) Adoption of the new carcass
Pirelli has been a single tire supplier for World Super motorcycle since 2004 and developing tires for the highest race of commercial motorcycles.
Through activities on this world super motorcycle, a new method has been developed that [it reduces the twist and increases the overall carcass strength by increasing the number of fibers].
[ANGEL GT] adopts a new carcass with the number of fibers + 32%: twist number -20% → tensile strength + 60%, and the tire expansion and deformation caused by the centrifugal force when the tire rotates at high speed Minimized, ensuring excellent straight-line stability and comfort.

2-1) Optimization of contact surface shape
< The center part of the tire is [Shorter] [Wider] [Larger]>
The center part of the tire is the most wearable part.
When analyzing the process that causes wear, It is known that the tire starts to slip immediately after the difference between the force transmitted from the road surface (tire outer part) and the force applied in the rotational direction of the tire (tire
inner part) becomes large and wear occurs.
Therefore, in [ANGEL GT], in order to shorten the time for the tire to slip and reduce wear, it is a contact surface type that has a short back and forth direction.
Form adopted.
On the other hand, by increasing the [Width] of the ground plane, It enlarges the whole area and secures a high grip.

< Tire Center Part → Shoulder Part → Edge Part [Vertical] >
While widening the contact surface shape of the center part of the tire and improving the straight running stability, it is also wide even in the process of banking
With the shape of the ground contact area, the handling becomes heavy.
So, in [ANGEL GT], the internal structure is tuned so that the ground contact area becomes [Longitudinal] as you bank.
This reduces lateral resistance and achieves sporty handling.
In addition, by extending the ground contact area in the vertical direction, the ground area is secured and high grip is exhibited.

2-2) Adoption of new the compound
While maintaining high wear resistance, it has developed a new compound before and after to exert its grip under all conditions such as rain and low temperature days.
The front tire is a 100% silica compound that emphasizes wet grip.
The rear tire features a 70% compound that emphasizes abrasion resistance at the center and a 100% silica compound that emphasizes wet grip at the shoulder, which further enhances wet grip and abrasion resistance.

3) Optimization of the groove
Optimized groove design according to changes in profile and contact area shape.
While inheriting high drainage [long groove] which has a reputation in ANGEL ST, It adopts a design corresponding to the higher speed.
Also, with the adoption of [Round Profile], the parts that were in charge of drainage in two grooves were integrated into one. The groove area is smaller (the seal and ratio is reduced), and the grip and wear resistance are improved.

•Thorough running test
Any good performance can be said that it is suitable for [Gran Turismo] only when it is demonstrated on all road conditions while traveling long distances.
Pirelli has a test headquarters in Sicily, Italy, and is conducting actual driving tests in a blessed environment with various road conditions, such as around volcanic rocky Mount Etna, concreted northwest road, and smooth southeast road.

The track where the World Super motorcycle was held [PERGUSA] circuit and the road race [Targa Florio] was also used as a test course, and it was a severe test to show the best trackability even in the presence of intense gaps and swells. In addition, Vizzola near Milan and Brazil Sumare 'have the same layout test course and set up an environment to test in different seasons of [Midsummer] and [Midwinter] at the same time. Being trained in such an environment, the [ANGEL GT] will perform well even in situations such as [the temperature dropped extremely from the Pacific side to the Japan Sea side and through the tunnel].

1) A new profile, which should be called tire skeleton, and a new material carcass developed on the World Super motorcycle.
2) Reviewing the internal structure, optimize the contact surface shape, and adopt a new compound
3) While inheriting the long groove that produced a wet performance that was well-received in ANGEL ST, It optimized the groove design according to changes in profile and internal structure

In this way, all of the tires are newly designed, trained through actual driving tests, and the tires [ANGEL GT] that travel safely and comfortably while maintaining performance such as sportiness and wet performance to a longer distance. Create and support [Gran Turismo = Grand Tour] from your feet.
