I am very happy to be one of the first batch of Raytheon tire evaluation users
Well, this driver cherishes this opportunity and takes it seriously. After evaluating 30,000 kilometers of travel, I came here to hand in my homework.
The general feeling is: very satisfied, it can be said that it is quite a surprise.
The most intuitive road noise suppression ability,Obviously, it crushed all the joint venture brands I have used before,Long-distance driving in both ears is geometrically reduced,Especially when dragging a tired body on the way back from a business trip,The noise reduction efficiency of Thor tires is really life-saving。 The attached tread and tread are optimized for domestic roads, with faster wet drainage, shorter braking distance, and lower chance of smashing nails. In everyday use, it can be described as a hexagonal warrior.
The only disadvantage in the body is that Jingyue's silent cotton is pasted in two sections, when driving at low speed in the quiet and smooth basement, the driver's seat will feel the pulse frequency of the two sections of silent cotton in the tire alternately on the ground, which is not disturbing, that is, at the beginning, you will always feel that something is stuck on the tire, and the speed is slightly faster.
First, after a year of new upgrades, continue to look at quietness first.
More than a year later, it finally ushered in a new upgrade of Thor Jingyue"silence pro", that is, the legendary Jingyue Pro. Then, I also ordered a set of Silence Pro to come back for early access to see if there were any bigger surprises in the upgrade of Jingyue Pro.
Unpacking and inspecting the goods, the materials are still sufficient from the original!The inner liner of the tire is made of a high proportion of butyl rubber formula, which brings the advantage of excellent pressure retention ability (no slow leakage), which I really have experienced in the use of Jingyue for more than a year.
The original tire should be weakly refilled at least once every other quarter when the temperature changes (the formula of individual special tires is reduced). Now I go back to the 4S shop for maintenance once a year, and the technician will check the tire pressure for me, I don't have to touch the tire at all, and the difference in the degree of worry is obvious!As a result, the emergency air pump I put in the car many years ago was about to swing into mold.
The sub-mouth glue is a high-quality styrene-butadiene material, with excellent tear resistance and tighter engagement with the rim.
The silent cotton is still a two-stage paste, but Leishen Jingyue Pro uses polyurethane foam with better physical properties, with greater thickness, higher density, larger volume, increased sound-absorbing area, and the theoretical sound-absorbing and noise-reducing effect will be further upgraded.
From the feel, you can also feel the change in the thickness and density of the polyurethane foam of Leishen Jingyue Pro.
After optimizing the arrangement of polyurethane foam, the density of the inner layer is smaller, and the density of the outer layer is larger, and the noise absorption effect of the step-by-step noise reduction is more ideal, and it is easier to isolate the tire cavity noise inside the tire.
Jingyue Pro compared with Jingyue, the tread design is obvious This time Jingyue Pro is more radical, both shoulders use open grooves, the displacement is larger and faster, and the main groove is also wider, providing better grip performance, but if you just do this tire according to this idea, the performance is definitely good, the silent effect may not be guaranteed, but through the multi-frequency pitch pattern of the computer, the noise is solved from the source, and then with the reinforced silent cotton, the tread design of Jingyue Pro can be more reversed!
The comparison between Jingyue Pro and Jingyue internal silent cotton, Jingyue is still firmly pasted inside the tire after 30,000 kilometers of use.
Jingyue Pro loading is completed!
Second, let's talk about the driving experience.
The first stop after Jingyue Pro got on the bus, it was surprisingly similar to a year ago, and it was back in the basement parking lot. The first feeling I have is that the rolling pulse feeling of the previous low speed on this smooth road surface has disappeared, and the thickened mute cotton is polished and cleaned by the 1000W high-power Han's laser machine, and then the new pre-sequence process of removing the oil film on the tread surface is pasted, and the effect of covering the pulse frequency of alternating landing is significant, and the working conditions that are easy to ignore are also fully covered, which is indeed admired.
After a simple dinner, I immediately went out to see the road noise and other data performance of Jingyue Pro, still running the same road and using the same equipment.
The decibel value of about 20 kilometers per hour is 581. The data is slightly better than Jingyue, but the impact of pressing through the joints of the road surface will be weakened.
At a speed of about 30 kilometers per hour, Jingyue Pro is also a slight improvement in data, but it is obviously more calm on the body shaking over speed bumps, and the harassment of rear passengers in and out of the community and around the school will be more gentle.
The speed is about 50 kilometers per hour, and the decibel value is 629,Basically the same as Jingyue,The difference is still in the physical sense,This speed is the most commonly used area of the main road in the city,Various pavement materials alternate and joints are the main sources of noise,Jingyue Pro In this case, rain and dew can be evenly wet,The high-frequency and sudden change of road noise is relatively gentle。
Starting at 80 km/h, there is a surprise!The decibel level drops significantly, and the sound pressure transmitted to both ears is greatly weakened (compared to loading tires), which is a speed area commonly used on general urban expressways, which effectively reduces the difficulty of communication between people in the car.
The speed is about 100 kilometers per hour, and the decibel value is 846, what kind of concept is this, it is already the cabin sound insulation performance of many intermediate cars, I really didn't expect to be able to achieve it on Leiling, this kind of calm and silky driving texture, for people like me who often have to travel across the Greater Bay Area is really rare.
At a speed of about 110 kilometers per hour, the performance continues to be outstanding, and the noise that can be perceived by the whole cabin is mainly wind noise, and the road noise is canceled by the polyurethane foam inside the tire and closed inside the tire. And compared with Jingyue, Jingyue Pro's noise reduction skills are more biased towards the performance of medium and high-speed states.
Attached is a comparison of several commonly used speed segments of loading tires, Jingyue, and Jingyue Pro.
The summary is: Thor Jingyue Pro compared with the old Thor Jingyue, the faster the speed, the quieter!
Next, it's time to examine the performance of Jingyue Pro.
Due to the influence of Typhoon Haikui's cloud system, the weather in the Pearl River Delta has been unstable, and it is difficult to wait until the evening when the rain stops, but it is difficult for the ground to dry out!There was no choice but to do the test in semi-wet and dry ground conditions.
Since 0-100 is meaningless for buying grocery cars (there is data in Jingyue in the past, you can read it), I will directly test 100-0 this time, after all, braking performance is the lifesaver in daily driving.
On a wet concrete test surface with 30% of the ground to dry, a 100-0 braking distance was measured at 39At 23 meters, the results maintained the high level of Jingyue, in addition to the use of open grooves on the shoulders to speed up the drainage, the raw material colloids optimized for the SIO content ratio also strengthened the wet performance and rolling resistance of the tires. It has stronger adaptability to the vast geographical and climatic environment in China.
The high-rigidity tread pattern design increases the ground contact area and improves the longitudinal grip. The reinforced ribs ensure the stability of lateral grip, and the actual cornering handling stability is not weakened by the mute orientation, and it is still possible to take a hand at Ono when encountering challenging sections in daily driving.
To sum it up in the end:
Under the condition that Jingyue ** remains unchanged, Jingyue Pro has further improved the mute performance under the optimization of polyurethane foam structure and the improvement of the pasting process, and it has been strengthened in the more necessary medium and high speed state.
It should be emphasized that from the original single pattern + 38 specifications to the current 5 patterns + 51 specifications, Thor Tire Jingyue Pro can be said to have been upgraded quite carefully. While achieving the above goals, the high adaptability of Jingyue Pro is still there, and it has not been lost, and it is still all-round on the radar. Really pleasantly surprised!
