inch inch tires in the end what is the difference?

2017 nian 10 9, tire commercial networks today and we discuss a common but difficult to answer a question:17 inch, 18 inch, 19 inch tires in the end so what's different? an obvious fact is that more than 17-inch tire share is rapidly increasing, whether it is from michelin, ma card, goodyear, hankook, rounds of jinyu data show that more and more depots and users prefer to use larger specifications the tires.smaller tires such as 13-inch, 14-inch, or even 15-inch tires in addition to low profits, the price is very low retailers are reluctant to sell.usually the more advanced the size of the car's tires, the more expensive, of course, the more expensive the price.

is a 17"wheel more comfortable than the 18"wheel? is a 19"wheel more sporty than its 18"little brother? as usual tire business network to explore-experiment speak! to see exactly what 17-inch, 18-inch, 19-inch tires in the end what is the difference? in order to answer the question of what happens when the user changes the wheel size, we use three different sizes of tires from the eagle f1 asymmetric 3 product of goodyear goodyear and tested the field test using the volkswagen golf gti.this objective test includes dry ground handling, dry ground braking and wetland control and wetland braking as well as cornering water skiing.let's take a look at the different results of straight and curved dry and wet water driving.we also conducted a professional nvh(noise, vibration and roughness) test to see if it was really possible to make the car more comfortable by changing the wheel size.

the selected tires are very simple, they are three oe of golf select the product.225/45 r17, 225/40r18 and 225/35r19 all have the same tire width, and the roll radius error is less than 0.4%, meaning they should have almost the same footprint.therefore, the measured performance difference will be attributed to the tire structure, rather than any other factors.

objective data

each of the three tires sizes are almost identical in size, and the original number of tire performance will be different? yes, but few.

braking performance is almost no difference, dry ground handling performance 19-inch tires faster.but the wetland control performance point of view, but is 17"tires the fastest, and wetland development performance look 18"tires best.curved water skiing is also the best 18-inch tires.so the current objective data, these three specifications of the tires almost no substantial differences.at least objectively speaking, the three tires are very similar in size to almost the same size.

degree.objective data is very close, we turn to the subjective treatment of tires and feel the real difference.

during the test, the subjective feel of the tire is shortened as the size becomes larger.19"is not the fastest lap because the maximum wheel size provides more grip, but because the tire turns more sharp and sensitive, and the 17"tires make the car feel soft and vague, 19"to the driver confidence and stability, the difference between 18"and 19"is much smaller than the difference from 17"to 18"but is still somewhat different.

in order to prove that there is no simple formula to follow, the subjective wetland control test[/p]

the results are exactly the opposite.the greater confidence and predictability of the greater tires in the dry land is replaced by tension and faster loss of grip in the wetlands.17"tires but the best performance, when the replacement of the wheel to 18", the control of this model is more concentrated in the front, which means that you have to be more careful behind, and 19"tires began to appear at this time due to uncertainty.the difference between 18"and 19"wheels is much less than 17"and 18"tires compared to dry ground control.

3"comfort and noise

is this nvh(noise, vibration and roughness) test results better explain the comfort problem? of course, let's take a look at the conclusion.

18"tires are still quite comfortable.but the 19"tires, the car completely different began to collapse(poor comfort).

this is the result of this test.
