Can Chinese tires compete with high-end tires such as Michelin PS4? At first, it was hard to believe it, until I saw the tire test of pacific auto network.
Good Luck No. 1 is one of the high-end series products of Zhongce Rubber's "Four Big No. 1", which is positioned as a quieter high-end tire, focusing on silent and comfortable performance.
Pacific Auto Network compared this tire with the original tire of Tesla Model 3 - the famous Michelin Racing Pilot Sport 4 (referred to as PS4), through static and dynamic testing, so that everyone can have a comprehensive understanding of the two tires.
It is reported that the test was carried out on a professional closed road, the test model is Tesla Model 3, and the tire specification is 235/45 R18.
Static testing
Luck No. 1 adopts an asymmetrical pattern design to improve traction and wet grip; continuous center ribs provide a better handling experience; longitudinal pattern grooves are optimally arranged to improve traction performance, and noise reduction steps are added at the bottom of the groove to improve the silent performance of tires.
The tread of Good Luck No. 1 has 2 layers of steel wire + two layers of fiber + 1 layer of nylon; the tire wall has 2 layers of fiber, which is in line with its high-end positioning in the number of tire curtains. The shoulder half groove has better grip in wet and slippery road conditions, and the four gutters provide perfect drainage.
After measurement, the average hardness of the tread of the Good Luck No. 1 is 64HA, and the hardness of the side is 56HA, which means that the tire has excellent performance in wear resistance.
The Michelin PS4 focuses on grip and handling, especially in the wet state, and the grip performance is very prominent.
The average hardness of the Michelin PS4 tread is 65HA and the sidewall hardness is 58HA.
Overall, the hardness difference between the two tires is not large, and the materials and design have their own advantages. The Michelin tread and sidewall are harder and more wear-resistant; good luck No. 1 is softer and the overall grip will be better.
Dynamic testing
In the dynamic test session, Pacific Auto Network tested the 0-100km/h acceleration and 100-0km/h braking performance of the two tires on dry and wetland roads, and also carried out 60/80/100 (km/h) tire noise test, pile winding test and rolling resistance test.
1. Dry land test results
After testing, the original Michelin PS4 has an acceleration time of 5.71 seconds at 0-100km/h in dry land and a braking distance of 36.8 meters at 100-0km/h.
The 0-100km/h acceleration time of Good Luck No. 1 dryland is 5.72 seconds, and the braking distance of 100-0km/h is 36.3 meters.
As can be seen from the dry ground results, there is only a slight difference in the acceleration performance of the two tires by 0.01 seconds; in terms of braking distance, the braking distance of the Good Luck 1 is better than that of the Michelin PS4, and the safety is higher.
2. Wetland test results
In the case of wetlands, the Michelin PS4 has an acceleration time of 0-100 km/h of 6.93 seconds and a braking distance of 41.6 meters for 100-0 km/h.
The acceleration time of 0-100km/h in The Good Luck No. 1 Wetland is 7.01 seconds, and the braking distance of 100-0km/h is 42.2 meters.
In contrast, the wetland performance of The Good Luck No. 1 lags behind the Michelin PS4, but it is understandable that the Michelin PS4 is the sports tire with the best performance in the wetland, and as a silent comfort tire, it is very difficult for the Good Luck No. 1 to have such a close performance.
3. Tire noise test results
After testing, the Michelin PS4 achieved an interior noise score of 62.5dB, 64.0dB and 65.2dB at a constant speed of 60/80/100 (km/h), respectively.
The Good Luck 1 achieved an interior noise score of 61.6dB, 62.7dB and 64.4dB at a constant speed of 60/80/100 (km/h). It is not difficult to see that in terms of silence, the domestic good luck No. 1 has comprehensively crushed the original Michelin PS4, which is more in line with the low noise characteristics of electric vehicles and creates a more comfortable riding experience.
It is reported that the reason why Good Luck No. 1 has achieved such good tire noise results is the use of a variable pitch pattern design and the noise reduction steps mentioned above.
The lateral pattern and diamond angle treatment make the tire perform quite well in acceleration and braking.
4. Test results around the pile
The pile winding test tests the grip of the tires and their stability at their limits, with the higher the score, the better.
After testing, the top speed of michelin PS4 is 52km/h, and the top speed of Good Luck 1 is 57km/h.
Lucky 1 won the pile-winding test, with the tire having no noticeable drop in grip and traction after continuous steering.
5. Rolling resistance test results
The Michelin PS4 has a neutral sliding distance of 288 meters and Good Luck 1 at 298 meters in the dry land case of 40 km/h-0, and a neutral taxi distance of 301 meters in the 40 km/h-0 wetland case and 311 meters at Good Luck 1.
In the rolling resistance test, the Good Luck 1 has a longer sliding distance, so it is more energy-efficient.
Mountain road experience
Pacific Auto Network replaced the original Michelin PS4 of tesla Model 3 with a Good Luck 1 and went to the mountain road for a driving experience.
The media said that Good Luck No. 1 is worthy of its high-end positioning, stepping on the brakes when entering a sharp bend, the driver can get good brake feedback, can judge the bend in advance, and make a higher speed into the corner.
The strong grip of the tires makes the car accelerate very smart when cornering, and the high-strength tire wall reduces the tilt of the car body when cornering, so that the driver has more confidence.
Even in the Tesla Model 3 electric car, the noise emitted by the tires is not felt, the quiet is excellent, and when passing uneven roads, the tires can provide good shock absorption, and the riding comfort is superb.
Overall, Good Luck No. 1 in this showdown, a number of test results beat Michelin PS4, and even some of the results are quite close, to know that Michelin PS4 in the circle is very well-known, is the first choice for high-performance car owners to upgrade tires.
The Good Luck 1 takes into account the handling performance under the premise of ensuring silent comfort, and it is completely worthy of being a quieter, more durable and safer high-performance tire.
