Tyre IRC SIREN COMP 20x1-3/8

The tyre IRC Siren Comp is directly inspired by the high-end profile used by Elite riders on the world circuit. Developed by the renowned Japanese brand IRC, this model from the Comp range is designed to offer an excellent balance between grip, performance and durability, all at a particularly attractive price-to-quality ratio.

It shares the clever tread design of the Pro version: an ultra-fast-rolling centre section that eliminates friction when pedalling to promote top speed, combined with micro side knobs to secure cornering lines. Its reinforced wire bead structure provides excellent impact resistance and long service life, making it the ideal companion for clocking up training laps or lining up for first competitions.

What is the difference between the Siren Pro version and this Siren Comp version? The Pro version uses an ultra-lightweight carcass with folding beads and a soft compound that maximises chemical grip for pure competition. The Siren Comp version uses wire beads and a slightly more robust compound. It is marginally heavier, but offers superior longevity and a much more affordable price, making it ideal for daily training.

Is this tyre suitable for riding on a wet or muddy track? The Siren Comp has a low-profile, speed-focused tread pattern. Its grooves disperse light water on the tarmac sections of corners, but it is not designed for very muddy tracks or loose terrain where deep knobs are required.

How should I set up my Siren Comp tyres on my BMX? You can fit it front and rear without any issue. For optimal handling, it is recommended to choose a wider size at the front (e.g. 20x1.75 or 20x1.90) to ensure precise and confident steering in corners, and a narrower size at the rear (e.g. 20x1.60) to promote responsiveness when pedalling.
