Does a Smaller Wheel ET Value Result in More Concave Wheels?

[LeBradley]

ET value determines the inner space of the wheel. A smaller ET value results in more inner space, while a larger ET value causes the wheel to retract further into the wheel arch. Here are the details: 1. Introduction to ET: ET stands for 'EinpressTiefe' in German, meaning 'insertion depth.' The ET value, or Off-set value, indicates the deviation of the wheel's mounting surface from the centerline of the rim, categorized into positive, zero, and negative. 2. Impact of ET value: Changing the ET value alters the vehicle's track width, influencing the tire's structure to some extent. The choice between a larger or smaller ET value depends on the driver's preferences. If the goal is to enhance the vehicle's cornering limit speed and reduce weight transfer during turns, opting for rims with a smaller positive ET value is recommended, as it widens the track width to meet the driver's needs. However, a smaller ET value also has drawbacks, such as increased steering difficulty, added load on the steering mechanism, and greater deformation of the steering gear.
