Spoked Hollow-Tread Flat-Free Wheels
Tread
Pattern
Also known as semi-pneumatic wheels, these have a tough, puncture-resistant tread surrounding a nonpressurized pocket of air to cushion like a pneumatic wheel without going flat. Their spoked hub keeps them lightweight at larger sizes. Ball bearings in the wheel provide easy rolling. They have center-mount hubs for equal clearance on both sides of the wheel.

Band Saw Wheel Tires
Also known as band saw rubbers, these tires provide a cushion between the blade and wheel to preserve tooth shape by reducing vibration and blade slippage. All are approximately 20% smaller than the compatible wheel diameter listed for a stretched fit. Secure them with adhesive and trim the width with a razor blade.
Polyurethane tires last longer than rubber tires.
