The term describes tires characterized by a short sidewall relative to their width. This dimensional relationship affects the overall diameter and appearance of the wheel and tire assembly. For instance, a tire designated 225/45R17 has a sidewall height that is 45% of its section width (225mm), making it a lower profile than a 225/60R17 tire.
Adopting this design offers performance advantages such as enhanced handling, increased stability during cornering, and improved responsiveness. The shorter sidewall reduces flex, leading to a more direct connection between the steering input and the vehicle’s movement. Historically, these tires were primarily found on performance vehicles; however, their usage has expanded to include a wider range of passenger cars for aesthetic and performance reasons. Conversely, the reduced sidewall height can diminish ride comfort and increase the risk of damage from road hazards.
