Plus sizing is one of the easiest ways to achieve an improved performance and appearance of your vehicle. However, it is important to note that although the wheel diameter can be increased, the overall diameter of the tyre should remain consistent.
Two things happen to the tyre when moving into plus sizes. First, the tyre becomes wider due to an increase in section width. This provides a larger footprint and more contact with the driving surface. Second, the aspect ratio is lower, resulting in a shorter sidewall. The combination of these changes offers better lateral stability and increased steering response.
