Car flying less than 10,000 kilometers, upgrade 195 wide tires, and finally compromise comfort!

Manual GK5 has been in operation for one year and three months, with a distance of 9800 kilometers. After finding the naturally aspirated engine again, the feeling of low speed and softness came back. I have to say that Fit is very suitable for urban road conditions, and it drives smoothly. . The disadvantage is that the vibration filtering performance is average, and there are more trivial vibrations of the car when encountering potholes and gravel on the road, and the tire noise is also relatively large.

Original Deng Lupu EC300 positioning is fuel-efficient and practical, with good wear resistance, which fits the positioning of Fit and frugal home. And this kind of tire with wide adaptability has no characteristics and general comfort.

As a family car, the third generation Fit deviated from Honda's original intention as soon as it went on the market, and kept running in the direction of track performance and extreme modification. GK5 seems to be a car where everything is possible, and everyone can make it look and feel what they want. I use Fit mainly for local traffic and slight modification, so I have higher requirements for comfort. After adding a lot of configurations in the car, I plan to start with the tires in the walking part.

My request is to reduce tire noise and bumps. Choose from several big brands, just in time for the promotion of Ma brand CC5, and this tire is quiet and comfortable. Judging from the reaction of second-hand car friends, the mute is good, and the tire quality is soft, which can isolate the trivial vibration of the road surface, but the disadvantage is that the wear resistance is not as good as that of the original tire.

But I don't care much about this shortcoming. Can't run in a year 1000 km. It is not a problem for big brands in the market to run more than100000 kilometers. More wear-resistant tires don't mean much to me, but the comfort I can always feel is what I need.

GK5 original tire is 185? 60R 15, since I'm going to change the tire, I'll upgrade the tire size within the bearing range of the hub and go directly to 195? 60R 15, wider tires can bring better grip and driving stability.

In fact, the tire with a leakage rate of 55 is selected, the wheel diameter is closer to the original factory and the speedometer is more accurate. However, due to the difficulty of parking near the unit and sometimes going on the road, the thicker 60 flat rate was chosen.

I changed it at a horse brand authorized store.

195 tires have no feeling in themselves, but when the old and new tires are put together, they are obviously a little wider than the tires of the original car 185, and they can feel a little softer than the EC300 tires of the original car by pressing the tire wall by hand. The pattern design of CC5 is also more complicated than that of EC300. The staggered patterns and holes in the middle are said to interfere with tire vibration, which is the so-called "3D active noise reduction" technology claimed by the manufacturer.

The tire DOT date is the 24th week of 2020.

Four tires were carefully inspected before loading.

Remove the wheels and lift the frame with four jacks.

The equipment was very professional, and four tires were dismantled in a short time.

After changing the tire, I did dynamic balance, and the master specially asked me to install the tire pressure monitoring sensor before doing it, which was more accurate.

The new tire is on the upper body and I feel very fat. After all, it's one size bigger and quite plump.

Ask the master to wrap the four original tires with plastic wrap.

The original tires were taken home, and the trunk was full.

It took a few days to change the tire. Let me talk about my feelings below: noise: the main appeal of tire change is to reduce noise. The reason why the three-generation Fit is dubbed as "Super Run GK5" is not only the strongest driving force at the same level, but also the poor sound insulation effect. The roar of the engine is pleasant to some people, but no one likes the noise of the tires. The rubber of the original tire is hard and the road noise is loud, which may be the common fault of wear-resistant tires.

The subjective auditory feeling after tire changing is that the car is much quieter and the engine sound is more obvious and pure. Before, the engine noise mixed with tire noise was very uncomfortable. For car fans, reducing tire noise means hearing a purer engine roar, which really improves a lot. The original road surface was slightly rough and the tire noise was relatively loud. Now, softer tire quality has a wider adaptability to noise. If you are on a smooth road, it is simply a quiet enjoyment. Only the sound of the engine controlled by the depth of the throttle will make people feel that money is not wasted at this moment, hehe.

Shock absorption: It is also because the tires are hard, and the comfort of the original tires is very general. If the road conditions are slightly worse, you will feel bumpy. The tire quality of CC5 is soft, so I chose size 60. Thick and soft tires have a good cushioning effect and can filter out many trivial feelings on the road. When crossing potholes, the original tires are thumping, and CC5 is thumping. It is more comfortable physically and audibly.

It is estimated that many people will ask what the speed bump feels like, and they can only say that it has not improved much. After all, for shock absorption, the role of shock absorbers is far greater than that of tires. Soft tires can better cope with small bumps such as gravel and asphalt joints, but it is difficult to cope with poor road conditions and large potholes by tires alone. The new tires improve the driving quality of Fit, reduce the cheapness of previous suspension, and make the rear passengers feel more comfortable than before.

Acceleration: Generally speaking, changing wide tires will affect the horsepower on the wheels, but the power of GK5 is surplus for family cars, so I don't feel any attenuation of power. Of course, I am not a professional cyclist. I haven't measured the difference between 0 1 and track lap speed before tire change, but from my own sense of acceleration, I don't feel any impact on power.

Grab the ground: wide tires will naturally improve the grip and have a large contact area with the road. This is the principle of physics, there is nothing to say.

Maneuverability: The softer tire texture makes the tire feel more sticky, and the wider tread can also provide better support and friction, and the handling is more confident after changing the tire. Especially when turning at a faster speed, the feeling of slipping out in the past is gone, and the car can firmly grasp the road surface and better perform the driver's operation, that is, the handling limit of the whole car has been slightly improved.

In short, as some riders say, changing tires is just like changing cars. Although it's not so exaggerated, the noise and shock absorption have been obviously improved after the Fit has changed the silent tires, which makes this 70,000 car feel a bit upscale, and at the same time, the handling and grip have also increased the driver's confidence. Perhaps the soft tire quality makes the wear resistance of CC5 insufficient, but for people with short mileage, better driving texture and driving comfort may be more meaningful.
