FAQs

Is the WTB Raddler suitable for all gravel conditions?

The Raddler is best suited for loose, mixed, and challenging gravel terrains where traction is a priority. It performs well but may not be the fastest on smooth, hard-packed surfaces.

What is the main difference between the Raddler and the Riddler?

The Raddler is a 'radder' version of the Riddler, featuring slightly taller center and intermediate knobs for increased tire lifespan and more aggressive outer knobs for enhanced cornering traction on loose terrain.

Can I use the WTB Raddler with tubes?

Yes, while designed for tubeless, the Raddler can be used with traditional inner tubes if preferred. However, tubeless setup generally offers better ride quality and puncture resistance.

How do I choose between the 700x40c and 700x44c sizes?

The 40c offers slightly quicker acceleration and less rolling resistance, while the 44c provides a larger contact patch for increased comfort and traction on rougher terrain. Consider your frame clearance and riding priorities.

What tire pressure should I use?

Tire pressure depends on rider weight, terrain, and tubeless or tube setup. Generally, lower pressures (25-40 PSI) are recommended for tubeless gravel tires to maximize grip and comfort, but always consult WTB's recommendations and your own experience.

How durable are the side knobs?

The side knobs are designed to be long and 'toothy' for aggressive cornering. While durable, they are part of the tire's aggressive tread pattern and can wear faster than center knobs if used frequently on pavement.

Troubleshooting

Tire won't seat on the rim

Ensure the rim strip and valve are correctly installed. Deflate the tire completely, apply soapy water to the bead and rim, and try inflating again. A compressor may be needed for stubborn tires.

Slow sealant leaks

Rotate the wheel to distribute sealant and allow it to seal the leak. If a small puncture is visible, add more sealant or use a tire plug.

Reduced traction after initial wear

While the Raddler is designed for durability, extreme wear can affect grip. Inspect knobs for excessive rounding or damage. Consider replacement if performance significantly degrades.

Pros and Cons

Pros

  • Excellent traction on loose and varied gravel surfaces.
  • Balanced performance: good rolling efficiency meets aggressive cornering grip.
  • Durable design with increased knob height for longer life.
  • Instills confidence on challenging descents and technical sections.
  • Suitable for riders prioritizing grip and control over pure speed on hardpack.

Cons

  • May not be the fastest option on smooth, hard-packed surfaces.
  • Semi-slick design prioritizes grip over pure speed in certain conditions.
  • Can be more aggressive than a true file tread or slick tire.
  • Performance may vary depending on specific tubeless setup and tire pressure.

Setup, Compatibility & Care

Setup: The WTB Raddler is designed for tubeless compatibility, offering the best performance and puncture resistance when set up with sealant. Ensure your rim is also tubeless-ready. Mount the tire following standard tubeless mounting procedures, using a floor pump or compressor to seat the bead.

Compatibility: Available in various sizes, including 700c with widths like 40mm and 44mm, the Raddler is compatible with most gravel bike wheelsets that accommodate these dimensions. Always check your frame and fork clearance to ensure proper fit.

Care: Regularly inspect the tire for wear, cuts, or embedded debris. Clean the tire surface with water and a mild soap if necessary. For tubeless setups, check sealant levels periodically (every 2-3 months) and top up as needed to maintain puncture protection.
