What’s the difference between alloy wheels and steel alloys? Alloy wheels are primarily an aesthetic choice. Often they are purchased in larger sizes than those fitted in the first gear, and the car suffers from the benefits of inch-ups (eg. most roadholding, especially in curves). In many cases, alloy wheels also improve ventilation of the braking system. Negative aspects are related to the weight, often higher, and the caution to be used: pay attention to the sidewalks while parking, and bumps and holes if fitted with lowered tires, and don’t forget that wheels are part of the masses Suspended masses are very important because they are lighter components (tires, rims, brakes, suspensions …) plus they give benefits in handling performance in relation to saving weight .
