Tires influence grip, damping, and handling – whether on concrete, ramps, or dirt. Depending on riding style and surface, the tread pattern, width, and casing construction vary. Street tires are usually wider (2.35"–2.4"), with a smooth tread for maximum contact. Park tires prioritize low weight and faster rolling. Trail tires offer a more aggressive tread pattern for traction on loose surfaces. Many models can be run at lower pressures for increased cushioning on landings. BMX tires are designed for 20" rims, and some are tubeless-compatible. Popular brands include Cult, BSD, Maxxis, Stranger, and WTP.
