Why MST?

Taper design is superior to standard designed products
- Reduces moving or flexing of components
- Component life extended
- Reduced wear and fatigue = increased safety
Fully machined and truly round in critical areas
- Improved rim component and tire bead fit
Tire beads are secure and stable
- Air loss significantly reduced
- Helps tires run cooler and maintain consistent air pressure
- Increased tire life. Prevents wear and damage to sidewall
Knurless design
- Eliminates indexing or slippage between bead band and tire bead
MST lock rings have two engraved grooves
- Easily identifiable
- Only compatible with MST and WTR components
Fully compatible with 57″ and 63” Wedge Type Rim (WTR) components
