How to Convert Your E-Bike to Tubeless (And Why You Should)
If you're still running tubes in your e-bike tires, you're making every ride harder than it needs to be.
Tubeless lets you run 5-8 PSI lower than you could safely run with a tube. Lower PSI means better traction, a smoother ride, and fewer pinch flats. You also eliminate the friction loss from the tube rubbing inside the tire, which adds up over thousands of miles.
Here's exactly what you need to convert and how to do it right.
What You Need
For the tire itself:
- A tubeless-ready or tubeless-compatible tire (check the sidewall — it will say "TR" or "Tubeless Ready" or "Tubeless Compatible")
- Most new e-bike tires from Maxxis, Schwalbe, WTB, and Vittoria are tubeless-ready
- Budget tires that come stock on many e-bikes are usually NOT tubeless compatible
For the conversion:
- Tubeless valve stems (one per wheel) — usually $8-15 for a pair
- Tubeless sealant (Tommy Sealant, Stan's, Orange Seal are common brands) — one 16oz bottle does 4-6 tires
- Tire levers (plastic, not metal — metal can damage the tubeless bead)
- A floor pump or, ideally, an air compressor with a tank for initial inflation
Optional but recommended:
- Tire boot (a strip of material to patch a large cut if you get a bad gash)
- Core remover tool for adding sealant later
Step 1: Check If Your Rims Are Tubeless Ready
Not all rims work with tubeless. You need a rim that:
- Has a tubeless-compatible rim bed (no spoke holes exposed to the interior)
- Has the valve hole already drilled (most do)
If your rim has exposed spoke holes on the interior, you can add tubeless tape to seal them, but it's a more involved setup.
Step 2: Install the Valve Stems
Insert the valve through the rim hole from the inside. Screw the locking nut on the outside finger-tight — don't over-tighten.
Step 3: Apply Tubeless Tape
Wrap the rim bed with tubeless tape, starting just inside the flange on one side and going all the way around, overlapping by about 30% each wrap. The tape should be tight and wrinkle-free. Two wraps for extra security.
Poke the valve through the tape at the valve hole.
Step 4: Mount the Tire
This is the hardest part. Slide one bead over the rim starting at the opposite side from the valve. Work your way around both sides until the tire is seated on both beads.
This often requires a tire lever. Go slowly — don't use a metal lever on a tubeless tire as you can damage the bead.
Step 5: Add Sealant
Before mounting the last section of tire, inject 2-3 ounces of sealant into the tire through the partially mounted opening. Then finish seating the tire.
Step 6: Inflate
This is where an air compressor with a tank helps. You need a strong burst of air to seat the tubeless beads against the rim.
If using a floor pump, use a tubeless inflator (the lever-style that creates a vacuum seal) or pump rapidly with a second person holding the beads in place.
The tire should pop onto the rim with an audible "thunk." If it doesn't, check that the beads are centered in the rim channel.
Step 7: Spin and Check
Spin the wheel to spread the sealant around the inside. Check for bubbles at the beads — a few small seeps are normal on first setup and usually seal within a few minutes of spinning.
Let it sit for 30 minutes, re-check, and inflate to your target PSI.
Running PSI After Tubeless Conversion
Now that you don't have tubes, you can safely run lower:
| Tire Size | With Tubes (PSI) | Tubeless (PSI) |
|---|---|---|
| 2.0-2.4" | 40-50 | 35-45 |
| 2.5-3.0" | 30-40 | 25-35 |
| 3.0-4.0" | 18-24 | 12-20 |
The exact number depends on your weight and terrain — use our calculator to find your target.
When to Add More Sealant
Sealant dries out over time. In warm climates, check every 2-3 months. In cold climates, check every 3-4 months. If the tire has less liquid movement when you spin it, add more — usually 1-2 ounces per tire.
Bottom Line
Tubeless conversion costs about $30-50 in parts (valves + sealant + tape) and takes 30-60 minutes per wheel the first time. The payoff is fewer flats, better traction, and a more efficient ride.
