What is the difference between 18-inch and 19-inch tires?
1 Answers
18-inch and 19-inch tires have similar tire widths, and the rolling radius error is less than 0.4%, which means they should have almost the same footprint. The specific differences are as follows: 1. From the perspective of braking performance: There is almost no difference in dry braking performance between 18-inch and 19-inch tires, and the dry handling performance of 18-inch tires is faster than that of 19-inch tires. From the perspective of wet braking performance, 18-inch tires perform the best. Cornering hydroplaning is also best with 18-inch tires. So based on current objective data, there is almost no substantial difference between these two tire specifications. 2. From the perspective of subjective handling: During dry handling tests, the subjective feel of the tires shortens as the size increases. The fastest lap time with 19-inch tires is not because the larger wheel size provides more grip, but because these tires offer sharper and more responsive turning, while 18-inch tires make the car feel softer and less precise. 19-inch tires give the driver confidence and stability. 3. From the perspective of comfort and noise: 18-inch tires transmit more road bumps to the driver, especially in the rear of the car. The noise level of 18-inch tires is acceptable, but it can still be felt inside the cabin. When equipped with 19-inch tires, the car's comfort deteriorates significantly, and the ride becomes much harsher.
