Are Rims really the bigger the better
TIME:2020.01.10
When we buy a car now, we find that the hub of a high-profile car is usually larger than that of a low-profile car, and in many cases low-profile cars do not allow high-profile wheels, for those who like high-matching wheels and shy friends in the pocket will choose vice factory wheels, so when to choose wheels is the bigger the better? Advantages of large wheels 1. GOOD-LOOKING: No matter what brand the concept car has one thing in common, that is, the wheel hub has a sky-high size, no matter the details are good-looking or not, with a pair of big feet, the whole car is good-looking, so for many drivers, the main goal of changing the hub is to look good. 2. Can fit into a larger braking system: A car's braking performance is as important as its acceleration, which in turn is related to the performance of the brake Caliper, the performance of the Tyre and the weight of the car. If the rims are too small, you can't even replace the high-performance brakes. So in some cases this is a hard requirement to improve performance. But most of the time you don't get a more powerful braking system with bigger rims (or bigger rims because of the size of the brows) . Not only does it not look good, it also has a negative effect. 3. Road sense is stronger: This is important for performance control, but can also affect relative comfort. Disadvantages of large wheels 1. Poor Comfort: We all know that it's impossible for a car to have both extreme performance and comfort, so we have to choose a balance point that suits us. Generally replaced with a larger wheel tire size, in order to further increase the aesthetic degree, but also choose a flat lower (that is, thinner) tire, so that the comfort will be greatly reduced. After all, the thickness of the tyres is part of the shock absorption, which is why many comfort-conscious family cars choose thicker tyres. 2. IMPACT PERFORMANCE: right, increase the size of the wheel will not improve performance but will reduce, the size of the tire and wheel directly affect the rotation momentum and linear motion momentum, the popular saying is the cause of inertia. This includes the moment of inertia of the wheel and the inertia of the up and down motion of the wheel. The Tire Inertia directly affects the acceleration performance. Because the greater the inertia, the slower the number of revolutions, the slower the car will accelerate. If inertia increases, it affects both acceleration and braking. And reduce the wheel inertia is to consider reducing the weight of the first wheel, so that the choice of lightweight hub is the most direct way. So how do you choose the hub? 1. Start with the lighter stuff: Forging for the money, no money -- no money, no money. 2. Choose a center of mass distribution: something like this is definitely better, because most of the mass is near the center and has less of an effect on inertia. 3. Although the spokes less performance is better, but because of domestic road conditions, or choose more spokes hub, otherwise . . 4. Think the main reason for changing the wheel is to look good like a! (provided the quality is guaranteed)
