So You’re Going Tubeless – What You Need to Know
Now that you’ve decided to make the switch to tubeless bike tires, it’s important to understand the setup process, compatibility requirements, and ongoing maintenance to get the most out of your new system. A key part of this transition is ensuring that your wheels are tubeless-ready (TLR)—designed with a sealed rim bed to support an airtight system. Tubeless-ready wheels can come in two designs: hooked or hookless, and selecting the right tires for your rim type is critical for both performance and safety.
From choosing compatible tires to setting up your tubeless system correctly, this guide will walk you through everything you need to know before you ride.
Hooked Rims
Hooked rims, also called bead-lock rims, have a small hook on the inner edge that helps secure the tire bead in placewhen inflated. This has been the traditional standard for road, gravel, and MTB wheels and remains widely used today.
Key Benefits of Hooked Rims:
✅ Greater Tire Compatibility – Works with both tubeless-ready tires and standard clincher tires (with inner tubes).
✅ Supports Higher Pressures – Can safely handle higher PSI (90-120 PSI for road tires), making them suitable for both road cyclists and triathletes.
✅ More Tire Options – Since they accommodate both tubeless and traditional clinchers, hooked rims give you more choices when selecting tires.
Important Considerations for Hooked Rims:
⚠️ More Effort to Mount Certain Tires – Some tubeless tires have tighter beads due to the bead hook, making installation slightly more challenging.
⚠️ Slightly Higher Rolling Resistance – The bead hook affects how the tire sits on the rim, potentially increasing rolling resistance compared to hookless designs.
⚠️ Less Common in New Aero & Gravel Designs – Many modern wheelsets (especially aero road and gravel) are moving toward hookless designs for improved efficiency.
📌 Best for riders who want the flexibility of using both tubeless and clincher tires, or who frequently ride at higher pressures.
Hookless Rims
Hookless rims eliminate the bead hook, relying on tire bead tension and air pressure to create an airtight seal. They are becoming increasingly popular in road, aero, and gravel wheels due to their weight savings and improved tire interface.
Key Benefits of Hookless Rims:
✅ Easier Tire Installation – Without the bead hook, tubeless tires slide onto the rim more easily, reducing the struggle of mounting.
✅ Lighter & More Aerodynamic – Hookless rims allow for a wider, more structurally efficient rim shape, improving aerodynamics and reducing weight.
✅ Lower Rolling Resistance – The smooth interface between the tire and rim reduces rolling resistance, improving efficiency. Designed to run at lower PSI (typically 72 and under)
Important Considerations for Hookless Rims:
⚠️ Tire Compatibility is Critical – Hookless rims require tubeless-specific tires that meet ETRTO safety standards—you cannot use standard clincher tires.
⚠️ Lower Max Pressure Limits – Most hookless rims should not be inflated above 72 PSI, making them less ideal for riders who prefer high-pressure road setups.
⚠️ Can Be Difficult to Seat Initially – While installation is easier, seating the bead may require a high-pressure pump or compressor to achieve an airtight seal.
📌 Best for riders who prioritize ease of tire installation, lower rolling resistance, and improved aerodynamics—especially for gravel, endurance, and high-performance road cycling & triathlon.
Coach’s Perspective: Hooked vs. Hookless:
A Balanced Take
As a coach and rider, I use both hooked and hookless wheel setups, and each has its own advantages depending on the type of riding I’m doing. My triathlon and gravel bikes are hookless, which allows me to take advantage of lower rolling resistance, wider tire profiles, and a smoother ride on mixed surfaces. On the other hand, my road bike is hooked, giving me the flexibility to run both tubeless and traditional clincher tires, as well as allowing for higher pressures when needed.
There’s no universal ‘better’ option—what works best depends on your riding style, terrain, and personal preferences.If you prioritize versatility and tire choice, a hooked setup might be the right fit. If you’re looking for a more optimized tubeless system with lower rolling resistance and improved aerodynamics, hookless could be the way to go. Understanding the pros and cons of each will help you make the best choice for your riding needs.

required tools & supplies for Tubeless tires
Tubeless-Ready Wheels & Tires
- Confirm that your wheels are tubeless-ready (TLR)—not all rims support tubeless setups.
- Select tubeless-specific tires that match your rim type (hooked or hookless).
✅ Tubeless Rim Tape
- Used to seal the spoke holes in tubeless-ready rims.
- Choose a width that matches your rim’s internal width (e.g., 21mm for a 21mm rim).
- Some wheels come pre-taped from the manufacturer, but it's best to check for any gaps or weak spots.
✅ Tubeless Valve Stems
- These allow air to enter the tire and seal the system without an inner tube.
- Make sure the valve length is long enough for deep-section rims (e.g., 60mm+ for aero wheels).
✅ Tubeless Sealant
- A latex-based liquid that seals small punctures automatically.
- Typically 2-4 oz. per tire for road and gravel, more for MTB.
- Replace every 2-6 months to ensure effectiveness.
✅ Air Inflation System
- Best option: Air compressor or tubeless booster pump – Provides a quick burst of air to seat the tire bead.
- Alternative: High-volume floor pump (like a Joe Blow Booster) – May require multiple attempts.
✅ Tire Levers (Optional)
- Helps install tight-fitting tires, but use with caution to avoid damaging the bead.
✅ Soapy Water or Tire Mounting Lubricant
- Helps the tire slide onto the rim more easily and improves bead sealing.
Install or Validate Tubeless Rim Tape
Before installing your tubeless tires, ensure your wheels have properly applied tubeless rim tape to create an airtight seal. Some wheels come pre-installed with rim tape, but it’s always good to inspect for gaps, bubbles, or weak spots.
How to Check Your Rim Tape
- Look for tubeless tape covering all spoke holes—if missing or damaged, replace it.
- Press down on the tape to check for air bubbles or lifting edges.
- If in doubt, reapply fresh tape for a reliable seal.
Installing Tubeless Rim Tape
1️⃣ Choose tape that matches your rim’s internal width.
2️⃣ Start one spoke hole before the valve hole, keeping tension as you apply.
3️⃣ Overlap 1-2 inches past the starting point and smooth out air bubbles.
4️⃣ Use a sharp tool to poke a clean hole at the valve hole.
📌 Pro Tip: Two layers of tape improve sealing on some rims, especially for high-pressure road setups.
📌 Next Step: With the rim properly sealed, it’s time to install your tubeless valve stems.
install Tubeless Valve Stems
With your rim tape securely in place, the next step is installing your tubeless valve stems, which allow air to enter and maintain an airtight seal. A proper valve installation prevents air leaks and ensures smooth inflation.
How to Install Tubeless Valve Stems
1️⃣ Locate the valve hole and check that the rim tape covers it completely.
2️⃣ Poke a small hole in the tape at the valve hole—just enough to push the valve through without tearing the tape.
3️⃣ Insert the valve stem through the hole, ensuring the rubber base sits flush against the tape.
4️⃣ Hand-tighten the valve nut on the outside of the rim, securing the valve in place.
📌 Pro Tip: If air leaks around the valve, remove it and apply a small drop of sealant or rubber o-ring grease to improve the seal before reinserting.
Do You Need a Valve Extension?
For deep-section aero wheels (50mm+ rims), a valve extension may be required to ensure easy inflation.
✅ Check Your Valve Length:
- Standard 40mm valves work for most road and gravel rims.
- 60mm+ valves or extensions are needed for deep-section wheels.
✅ Choosing the Right Extension:
- Threaded extensions (best for removable valve cores) allow easy inflation and sealant injection.
- Smooth extensions require a separate inline adapter to remove the valve core for sealant access.
📌 Next Step: With the valves installed, it's time to mount the tubeless tires onto your rims.
mounting the tire onto the rim
With your tubeless valve stems installed, the next step is mounting the tire onto the rim. Proper technique ensures a secure fit, making it easier to seat the bead and prevent air leaks during inflation.
How to Mount a Tubeless Tire
1️⃣ Start with One Side – Place one side of the tire bead onto the rim, working evenly around the wheel.
2️⃣ Work the Second Bead On – Starting at the opposite side of the valve, push the second bead over the rim edge, finishing at the valve.
3️⃣ Use Soapy Water for a Smoother Fit – Lightly apply soapy water or tire mounting lubricant along the tire bead to help it slide into place more easily.
📌 Pro Tip: If the tire is especially tight, avoid using metal tire levers, as they can damage the bead or rim tape—instead, use plastic levers if absolutely necessary.
Common Mounting Challenges & Fixes
❌ The tire won’t go over the rim edge.
✔️ Ensure the opposite bead is sitting in the center channel of the rim, allowing more slack.
❌ The tire is loose or uneven on the rim.
✔️ Double-check that both beads are fully seated inside the rim’s channel before inflation.
📌 Next Step: With the tire mounted, it's time to add sealant and seat the tire properly.
Add sealant to the tire
How to Add Tubeless Sealant
1️⃣ Remove the Valve Core – Use a valve core remover tool to take out the core, allowing for easy sealant injection.
2️⃣ Shake the Sealant Bottle – This ensures the sealing particles are evenly mixed.
3️⃣ Inject Sealant Through the Valve or Bead – Use a sealant injector to add 2-4 oz. (road/gravel) or 4-6 oz. (MTB)directly through the valve stem.
4️⃣ Reinstall the Valve Core – Tighten it snugly to prevent air leaks.
📌 Pro Tip: If your valve stem is clogged with sealant over time, soak it in warm water and blow compressed air through it to clear the blockage.
Seating the Tire (Inflating for a Proper Seal)
1️⃣ Use a High-Pressure Air Source
- Best option: Air compressor or tubeless booster pump (provides an instant high-volume burst).
- Alternative: High-pressure floor pump (like a Joe Blow Booster)—may require rapid pumping.
2️⃣ Inflate Quickly – This helps snap the beads into place on the rim.
- Listen for popping sounds—this means the beads are locking into the rim bed.
- If the tire won’t seat, remove the valve core and try again for increased airflow.
3️⃣ Check for Air Leaks – If air is escaping:
- Rotate the wheel to spread sealant evenly inside the tire.
- Re-inflate and check for small gaps between the tire bead and rim.
📌 Pro Tip: If the tire isn’t holding air overnight, add more sealant, shake the wheel, and reinflate to help coat any small gaps.
🚀 Key Takeaways
✔ Sealant is critical for puncture protection and air retention—refresh every 2-6 months.
✔ A high-pressure air source makes seating easier—use a compressor or tubeless booster pump.
✔ If the tire isn’t sealing properly, reapply sealant and check for leaks before reattempting inflation.
📌 Next Step: With your tubeless tire seated and sealed, it’s time for final checks and ongoing maintenance tips.
Final checks & maintenance
Now that your tubeless tires are installed and inflated, it’s important to run through a few final checks to ensure a proper seal and maintain your system for long-term performance.
Final Installation Checks
✔ Check for Air Leaks – Spin the wheel and listen for hissing sounds that could indicate small leaks. If needed, rotate the tire to help sealant reach any unsealed areas.
✔ Inspect the Tire Bead – Ensure both tire beads are fully seated in the rim channel. If there are any gaps, deflate slightly and reinflate.
✔ Confirm Proper Tire Pressure – After seating, adjust PSI to match your riding style:
- Road: 60-90 PSI (hooked rims), ≤72 PSI (hookless rims)
- Gravel: 35-55 PSI
- MTB: 18-35 PSI
📌 Pro Tip: Leave the bike stationary for a few hours to allow sealant to fully distribute and seal any small imperfections.
Routine Tubeless Tire Maintenance
✅ Check & Refresh Sealant Every 2-6 Months
- Over time, sealant dries out, reducing its ability to seal punctures.
- Check by shaking the wheel—if you don’t hear liquid inside, it’s time to add more sealant.
✅ Inspect Tires for Punctures
- Small punctures often self-seal, but large cuts may require a tubeless plug kit.
- If the tire fails to hold air, add more sealant or consider replacing the tire.
✅ Clean & Maintain Valve Stems
- Sealant buildup can clog valves, making inflation difficult.
- Remove and clean valve cores periodically to ensure proper airflow.
✅ Carry a Backup Plan
- Always carry a CO2 cartridge, mini-pump, and a spare tube in case of a major puncture that sealant can’t fix.
📌 Pro Tip: If a puncture is too large for sealant to seal, use a tubeless tire plug before resorting to inserting an inner tube.
🚀 Key Takeaways
✔ Monitor sealant levels regularly to maintain puncture protection.
✔ Keep valves clean and clear to prevent inflation issues.
✔ Carry a repair kit on rides in case of a major puncture.
✔ Proper tire pressure optimizes performance—adjust based on your riding style and terrain.
📌 Final Step: With your tubeless tires fully set up and tested, you’re ready to enjoy a smoother, more reliable ride with fewer flats!
