You’re hearing about tubeless tires. Maybe at your bike shop, maybe from other riders, maybe in online reviews.
And you’re thinking: what’s the big deal? Why would I get rid of tubes? Isn’t that more complicated? Do I really need it?
Here’s the situation: tubeless tires are becoming the standard on mid-range and high-end bikes. They offer real advantages—fewer flats, better traction, smoother ride—but they also require more setup and maintenance.
The question isn’t “are tubeless tires better?” (they are, objectively, in most situations). The question is: are they worth the extra hassle for YOU?
This guide breaks down exactly how tubeless tires work, the pros and cons vs. traditional tubes, what the setup process involves, who should make the switch, and whether beginners should even bother.
Let’s figure out if tubeless is right for you.
The Quick Answer
Tubeless tires:
- No inner tube—tire seals directly to the rim with liquid sealant inside
- Fewer flats (sealant plugs small punctures automatically)
- Lower tire pressure = better traction and comfort
- More complex setup and maintenance than tubes
Traditional tubes:
- Inner tube holds air inside the tire
- Simple, cheap, easy to fix
- More prone to flats (especially pinch flats)
- Standard on most bikes
For most beginners: stick with tubes. Simple, reliable, cheap.
For serious riders (mountain, gravel, racing): tubeless is worth it. Performance advantages outweigh the hassle.
Still want details? Let’s break it down.
How Traditional Tubes Work
The system you probably have now:
- Inner tube sits inside the tire
- Tube holds the air (tire itself doesn’t hold air)
- Tire protects the tube from road/trail
- When you get a puncture: Air escapes through the hole, tire goes flat
Simple. Reliable. Been around for 100+ years.
How Tubeless Tires Work
No tube. Here’s what happens instead:
- Tubeless-ready tire seals directly to a tubeless-ready rim
- Rim tape creates an airtight seal (covers spoke holes)
- Tubeless valve allows air in, seals the valve hole
- Liquid sealant (1-4 oz) sloshes around inside the tire
- When you get a small puncture: Sealant rushes to the hole, plugs it, seals automatically
You keep riding. No stopping to fix a flat.
For bigger holes: Sealant might not seal it. You install a tube (yes, you can put a tube in a tubeless tire as backup).
Tubeless Pros
Fewer Flats
The #1 reason people go tubeless.
Sealant automatically plugs:
- Thorns
- Small glass shards
- Wire punctures
- Anything under 3-4mm
You hear a “psssst,” sealant seals it, you keep riding.
No more stopping every ride to fix flats.
No Pinch Flats
Pinch flats (snake bites) happen when you hit a hard edge (pothole, rock, curb) and the tube gets pinched between the tire and rim.
With tubeless, there’s no tube to pinch. Pinch flats are impossible.
This is huge for mountain bikers. Rocks and roots cause constant pinch flats with tubes.
Run Lower Tire Pressure
Without a tube, you can run 5-10 PSI lower.
Why this matters:
Lower pressure = more traction (tire conforms to the ground)
Lower pressure = more comfort (tire absorbs bumps better)
Lower pressure = better control (especially on loose or technical terrain)
For mountain biking and gravel riding, this is a game-changer.
Lighter Weight (Slightly)
No tube = less weight.
Typical savings: 50-100 grams per wheel.
Not huge, but racers care about every gram.
Smoother Ride
Tubeless tires feel smoother and more supple.
Why: Lower pressure + no tube friction = tires absorb vibrations better.
Tubeless Cons
More Complex Setup
Setting up tubeless is more involved than just slapping in a tube.
Steps:
- Install tubeless rim tape
- Install tubeless valve
- Mount tubeless tire
- Add sealant
- Inflate (sometimes requires an air compressor or special pump)
- Shake to distribute sealant
- Check for leaks
First time setup: 30-60 minutes (and possibly frustrating).
Once it’s set up, it’s fine. But initial setup is annoying.
Requires Maintenance
Sealant dries out over time.
You need to:
- Add fresh sealant every 3-6 months (depending on climate)
- Check tire pressure more often (tubeless can lose air slowly)
This is more work than tubes (which you just inflate and forget).
Messy
Sealant is liquid latex. It’s sticky and messy.
When you:
- Add sealant
- Fix a tire
- Remove a tire
- Get sealant everywhere
It’s not terrible, but it’s messier than tubes.
More Expensive Upfront
Tubeless setup costs more initially.
What you need:
- Tubeless-ready tires ($40-100 each)
- Tubeless-ready rims (most modern wheels are, but check)
- Tubeless rim tape ($10-20)
- Tubeless valves ($15-30 per pair)
- Sealant ($10-20 per bottle, lasts 2-4 tire setups)
- Possibly: tubeless pump or air compressor
Total: $100-200+ to convert both wheels.
Tubes: $10-20 total for two tubes.
Can Be Finicky
Sometimes tubeless just… doesn’t work.
Tire won’t seat properly. Sealant won’t seal a hole. Valve clogs. Rim tape leaks.
Experienced riders know how to troubleshoot. Beginners get frustrated.
Bigger Punctures Still Flat
Sealant works for small holes (under 3-4mm).
For bigger cuts or sidewall tears:
- Sealant won’t seal it
- You lose air
- You need to install a tube (carry one as backup)
- Or use a tire plug (requires practice)
Tubeless reduces flats, but doesn’t eliminate them.
Tubeless vs. Tubes: Head-to-Head
| Feature | Tubeless | Tubes |
|---|---|---|
| Flat resistance | Excellent (self-sealing) | Poor (any puncture = flat) |
| Pinch flats | Impossible | Common |
| Setup difficulty | Complex | Simple |
| Maintenance | Regular (add sealant every 3-6 months) | Minimal |
| Weight | Lighter (slightly) | Heavier (slightly) |
| Cost | Expensive upfront | Cheap |
| Ride quality | Smooth, supple | Slightly harsher |
| Traction | Better (lower pressure) | Good |
| Messiness | Messy (sealant) | Clean |
| Reliability | High (once set up) | Very high |
Who Should Go Tubeless?
Mountain Bikers
Tubeless is basically standard for mountain biking.
Why:
- No pinch flats on rocks and roots
- Lower pressure = more traction on loose terrain
- Self-sealing thorns and small punctures
- Better control and comfort
If you mountain bike regularly, go tubeless. It’s worth it.
Gravel Riders
Gravel riders benefit hugely from tubeless.
Why:
- Lower pressure = comfort on rough gravel roads
- Fewer flats from thorns, wire, glass
- Better traction on loose surfaces
Highly recommended for gravel riding.
Cyclocross Racers
Tubeless is standard in cyclocross.
Why:
- Lower pressure = traction in mud
- No pinch flats
- Lighter weight
Road Racers
Many road racers use tubeless now.
Why:
- Slightly lighter
- Lower pressure = more comfort without sacrificing speed
- Fewer flats during races
But: Road tubeless setup can be finicky. And road tires get fewer punctures than mountain/gravel, so the benefit is smaller.
Beginners
If you’re new to cycling, stick with tubes.
Why:
- Tubes are simple and reliable
- You’re already learning bike maintenance—don’t add complexity
- Tubes are cheaper
- You can always go tubeless later
Exception: If you bought a bike that came tubeless-ready, keep it tubeless. Don’t convert it back.
Casual Commuters
If you ride pavement casually, tubes are fine.
Why:
- Tubes work great on pavement
- Easier to maintain
- Cheaper
Tubeless benefits (lower pressure, traction) don’t matter much on pavement.
Touring Cyclists
Long-distance touring on tubes is often easier.
Why:
- Tubes are simple to fix anywhere in the world
- Sealant dries out (not ideal for months-long tours)
- Not every bike shop has tubeless supplies
Some tourers use tubeless, but most stick with tubes.
How to Set Up Tubeless (Overview)
This is a simplified overview. Full instructions vary by tire/rim combo.
Step 1: Check Compatibility
You need:
- Tubeless-ready (or tubeless-compatible) rims
- Tubeless-ready tires
- Tubeless rim tape
- Tubeless valves
- Sealant
Check your rim and tire. Look for “tubeless-ready,” “TLR,” “UST,” or “tubeless-compatible.”
If your rims aren’t tubeless-ready, you can sometimes make them work (with extra tape), but it’s not ideal.
Step 2: Install Rim Tape
Rim tape covers the spoke holes, creating an airtight seal.
- Remove old rim tape (if any)
- Clean the rim bed
- Apply tubeless rim tape in one continuous strip
- Press firmly, smooth out bubbles
- Cut excess, leaving a bit of overlap
Tape width matters. Measure your rim’s internal width and get tape slightly wider.
Step 3: Install Tubeless Valve
- Poke a hole in the tape at the valve hole
- Insert tubeless valve stem through the hole
- Tighten the valve nut (hand-tight, not over-tightened)
Step 4: Mount the Tire
- Install one side of the tire bead on the rim
- Pour sealant into the tire (1-4 oz depending on tire size)
- Or: Install tire completely, then add sealant through valve (requires sealant injector)
- Mount the second bead
This can be tight. Use tire levers if needed (but be careful not to damage the bead).
Step 5: Inflate the Tire
This is the tricky part.
Goal: Get the tire bead to “seat” (snap into place on the rim).
Methods:
Air compressor (easiest):
Blast of high-pressure air seats the bead instantly.
Tubeless floor pump:
Special pump with a chamber that releases a burst of air.
CO2 cartridge:
Quick burst of air. Works but uses CO2 (not ideal for sealant long-term).
Regular floor pump (hardest):
Pump fast and hard. Sometimes works, sometimes doesn’t.
You’ll hear a loud POP when the bead seats. That’s good.
Step 6: Shake and Check
- Shake the wheel (distributes sealant around the tire)
- Spin the wheel, look for leaks
- If sealant sprays out, let it sit—it should seal itself
- Inflate to desired pressure
- Let it sit overnight, check pressure in the morning
If it holds air, you’re done.
Step 7: Maintenance
Every 3-6 months:
- Add fresh sealant (old sealant dries into chunks)
- Check tire pressure regularly (tubeless can lose air slowly)
Common Tubeless Problems (And Solutions)
Problem: Tire Won’t Seat
Solution:
- Use an air compressor or tubeless pump (regular pumps often don’t work)
- Remove valve core, use compressor (more air flow)
- Add soapy water to bead (helps it slide into place)
Problem: Tire Leaks Air Slowly
Solution:
- Check rim tape (leaking through spoke holes?)
- Check valve (tighten or replace)
- Add more sealant
Problem: Sealant Won’t Seal a Puncture
Solution:
- Shake the wheel (distribute sealant)
- Inflate and ride (movement helps sealant find the hole)
- If it still won’t seal, use a tire plug or install a tube
Problem: Sealant Dried Out
Solution:
- Add fresh sealant every 3-6 months
- In hot climates, check more often
Problem: Valve Clogged with Sealant
Solution:
- Remove valve core, clean it
- Use a small wire or valve core tool
- Prevent: don’t over-tighten valve core (makes removal easier)
Tubeless Sealant Options
Popular brands:
- Stan’s NoTubes – Most popular, works well
- Orange Seal – Seals larger holes
- Muc-Off – Good performance, eco-friendly
- Finish Line – Budget option
- Slime – Cheap, works okay (not as good as bike-specific sealants)
How much to use:
- Road tires: 1-2 oz per tire
- Gravel tires: 2-3 oz per tire
- Mountain bike tires: 3-4 oz per tire
Can You Put a Tube in a Tubeless Tire?
Yes!
Carry a spare tube as backup. If you get a puncture too big for sealant to seal, install a tube and ride home.
How:
- Remove valve core (deflate tire)
- Break one bead
- Install tube (like normal)
- Inflate
Note: Sealant inside will coat the tube. Messy but harmless.
Should You Convert Your Current Bike to Tubeless?
Check if your rims and tires are tubeless-ready.
If yes:
Converting is fairly easy. Costs $50-100 (tape, valves, sealant, possibly new tires).
If no:
You’d need new wheels or tires. Expensive ($200-500+). Probably not worth it unless you’re upgrading anyway.
Easier: Just buy your next bike with tubeless already set up.
Final Thoughts
Tubeless tires are objectively better in most situations:
- Fewer flats
- Better traction
- More comfort
- Lighter weight
But they’re more complex and require maintenance.
Who should use tubeless:
- Mountain bikers (almost mandatory)
- Gravel riders (highly recommended)
- Serious road cyclists
- Anyone who hates fixing flats
Who should stick with tubes:
- Beginners
- Casual riders
- Commuters on pavement
- People who value simplicity
The good news: You can always switch later. Start with tubes, go tubeless when you’re ready.
