The track is the environment to test the best handling performance of a car, and for a good car, the tires it matches are also particularly important. The entire BMW 3 Series is currently the most popular model in the luxury mid-size car camp, and BMW has always been equipped with run-flat tires. Such tire models must take into account both safety and performance, and the requirements are extremely high. Basically only the first-tier international brands can provide them. The tires we are experiencing this time are from an emerging brand that has withstood the experience of American competitions - TRI-ACE. Its CARRERA Carrera model belongs to the passenger car tire series and is specially designed to continue running due to lack of air like the BMW 3 Series. Developed to meet vehicle needs.
In order to explore the ultimate performance of this powerful new product, we specially chose the Fugang Circuit in Huizhou, Guangdong. This track is 1.6 kilometers long and has a longest straight of 400 meters. It is a low-speed and multi-turn track, which is very suitable for testing the tire support and grip performance. The test model is the entire BMW 3 Series 325Li, equipped with a 2.0T turbocharged engine, with a maximum horsepower of 184PS, a maximum torque of 300Nm, and an acceleration of 100 kilometers per hour in 8.1 seconds. BMW has always been adhering to the handling attributes and the body design of the front-wheel drive layout, which are very suitable for showing off its skills on this multi-turn track.
About TRI-ACE Carrera series tires
The TRI-ACE brand originated from American racing events and introduced tire technology from motor sports into civilian products. The Carrera series tires developed this time to meet the demand for running without air are equipped with three major innovative technologies, which can bring a safer, more comfortable and fuel-saving driving experience. Currently, this model is available in 17-22 inches for sedans and SUVs, with a total of more than 50 specifications, fully meeting the tire replacement requirements of luxury brand models. This time we chose the 225/45 R18 95Y XL for the BMW 3 Series, which is consistent with the original specifications. It supports a maximum speed of 300km/h and a maximum load of 690kg, meeting the needs of high-performance models.
Carrera run-flat tire track experience
During the test, the surface temperature of the Fugang track was as high as 35 degrees, so after just two warm-up laps, the tire temperature reached an ideal state. With the use of ST steel wire, TRI-ACE Carrera tires can provide stronger lateral support for the body that rolls in corners, thereby making the cornering faster. Although the tread is made of low rolling resistance material, the reasonable tread design ensures sufficient grip. Therefore, whether it is the acceleration phase on a long straight road or the forced braking phase before entering a corner, the tread has excellent grip and is fully The performance of the Series 3 appears to be calm and unhurried.
However, because the new generation 3 Series is more comfortable in terms of chassis settings, the body is prone to large rolls and even tail swings on multi-curved tracks. If replaced with tougher shock absorbers, this TRI-ACE Carrera tire can achieve better performance.
It is worth mentioning that after more than ten laps of track testing, the wear condition of the TRI-ACE Carrera tires was also satisfactory. The tread pattern on the front of the tire tread is clear and full, the grooves are complete, and the tread blocks have no peeling or cracking. There is only one ring of obvious wear on the outside of the tire, which fully demonstrates that this tire maximizes the handling of the BMW 3 Series.
Summarize:
The launch of the TRI-ACE Carrera series of run-flat tires broke the monopoly of first-tier tire brands on the luxury mid-size car market and provided car owners with a more cost-effective tire replacement solution. TRI-ACE originated from American competitions and has a number of innovative technologies. Its products are also products after detailed market research and can better meet the needs of consumers in the Chinese market. The Carrera series tires I experienced this time not only take into account the characteristics of safety, comfort, and fuel economy, but can also show off their skills on the track. They are indeed the first choice for upgrading and replacing performance-class family cars.
