S&M Speedball Tire (20″, 22″, 26″, 29″)

The S&M Speedball is a multi-size tire series featuring a distinctive multi-edged "S&M" shoulder tread design engineered for cornering traction. The tread pattern varies by size to match intended use—20″ versions prioritize street riding with a smooth center strip for reduced rolling resistance, while 22″, 26″, and 29″ models use a broken center tread for improved grip across dirt, street, and park terrain. Available in multiple widths and diameters to suit different frame geometries and riding styles.

Key Features

• Multi-edged shoulder tread – Aggressive "S&M" pattern on tire shoulders digs in during cornering, providing grip when the bike is leaned over without sacrificing center tread efficiency
• Size-specific tread design – 20″ models use smooth center strip for street-focused speed; larger sizes use broken center knobs for multi-terrain traction
• Multiple width options – 2.25″ and 2.40″ widths allow riders to choose between clearance-friendly sizing or increased contact patch and stability
• High-pressure capability (20″) – 20″ versions rated to 110 PSI for firm, responsive feel and durability on street obstacles
• Optimized pressure range (22″-29″) – Larger sizes rated to 70 PSI, appropriate for the increased volume and intended multi-terrain use

Compatibility and Ideal Use Cases

The Speedball fits standard BMX rims in corresponding sizes (20″, 22″, 26″, 29″). Verify frame and fork clearance for your chosen width—2.25″ models work in tighter clearance situations including frames with minimal chainstay space or during grinds and spine transfers, while 2.40″ versions require more clearance but provide increased stability. The 20″ versions are optimized for street riding with fast rolling and grind clearance. The 22″, 26″, and 29″ models with broken center tread perform well across dirt, street, and park, making them suitable for riders who move between different terrain types. Both widths work effectively on front or rear, allowing matched pairs or mixed setups based on preference.
