Best 20 x 2.35 Bicycle Inner Tubes for Tricycles
Two 32mm Schrader tubes built for the wide 20 x 2.125 to 2.40 band, with 2.35 near the top of the range.
Updated · 2 min read · 2 products evaluated
A 20 x 2.35 tire is a broad, high-volume profile, about 60 millimeters wide on a 406 bead seat, and it brings real cushion to a compact trike wheel. Because 2.35 sits near the upper end of the 2.125 to 2.40 tube band, it stretches the rubber more than a 2.125 tire would.
Both tubes here are YunSCM butyl builds with a regular 32mm Schrader valve, differing mainly in pack count and a stated ETRTO code. The choice is simple, but the fitting detail matters on a wide tire where a pinched tube is easy to cause.
Short answer
The YunSCM two-pack is the better pick because it prints the ETRTO 54/64-406 band, which places 2.35 comfortably inside, and gives you a spare tube for the next flat. The YunSCM single suits a rider who only needs one emergency tube and wants the smallest bulk in a basket.

Best Overall1 of 2
YunSCM 20 x 2.125-2.40 (54/64-406) Bike Tubes, 2-PCS
A two-tube pack with a printed 54/64-406 band that places a 2.35 tire inside its range.
Best for
Wide 2.35 trike tires needing a spare
Why we like it
This pack covers 20 x 2.125, 2.20, 2.25, 2.30, 2.35 and 2.40 with an ETRTO code of 54/64-406 and a regular 32mm Schrader valve. The butyl compound is described as sealing well and resisting ozone and aging, and the maker advises adding a little air before installation to avoid a pinch flat.
Against the single YunSCM tube it doubles the count and prints a clearer ETRTO code. A 2.35 tire sits in the upper half of that band, so the tube is stretched moderately, which is fine for steady paved use but less ideal under heavy cargo.

Best Single Spare2 of 2
YunSCM 20 x 2.125-2.40 Schrader Tube, 1-Pack
A single 32mm Schrader tube for riders who only need one emergency tube in a basket.
Best for
One compact spare
Why we like it
This single tube names 20 x 2.125, 2.25, 2.30, 2.35 and 2.40 with a regular 32mm Schrader valve. The maker suggests dunking the tube in water before use, because bubbles show a defect, and checking the valve sits straight after fitting.
It prints no ETRTO code, unlike the two-pack, and covers only one flat. It suits a rider with fresh tires who wants the least bulk and accepts a single spare.

How We Chose These 20 X 2.35 Bicycle Inner Tubes for Tricycles
- 2.35 inside the band
- A tube had to name 20 x 2.35 or a band containing it. We noted that 2.35 sits in the upper half of a 2.125 to 2.40 range.
- ETRTO code
- A printed 54/64-406 band lets you verify fit against your sidewall. The two-pack states it, and the single does not.
- Valve fit
- Both use a regular 32mm Schrader, which clears most small rims and fender stays. We confirmed the valve type on each.
- Pack count
- Two tubes give a spare for the next flat, while a single is the lightest kit. We ranked the pack higher at the same fit.
What to Look for in a 20 X 2.35 Bicycle Inner Tubes for Tricycles
Upper-band stretch
A 2.35 tire is about 60 millimeters wide, inside the 54 to 64 millimeter ETRTO band, but in its upper half where the tube stretches more.
More stretch thins the wall, so a rider with cargo should keep pressure correct and check the tire for debris. Light paved use is easy on a stretched tube.
Reading 54/64-406
The code gives tire widths from 54 to 64 millimeters on a 406 millimeter bead seat, which is a true 20 inch rim.
Compare it with the code on your tire sidewall, ideally 60-406 for a 2.35. If your tire reads narrower, step down to a 1.75 to 2.125 band.
Fitting a wide tire
A wide high-volume tire has a lot of air space, so a tube can fold or twist inside it during fitting.
Add a little air first so the tube holds shape, seat the bead evenly on both sides, then inflate slowly. Check the valve sits straight in the rim hole.
Spare strategy
A wide tube is bulkier than a slim one, so a single spare takes more basket room than you might expect.
A two-pack covers the next flat and leaves one for another day. If space is tight, a single and a small pump can be enough for local rides.
How to Choose
By Spare Strategy
| Situation | Our pick | Why |
|---|---|---|
| Regular rides with cargo room | YunSCM 20 x 2.125-2.40 (54/64-406) Bike Tubes, 2-PCS | Two tubes and a printed ETRTO band |
| Minimal basket space | YunSCM 20 x 2.125-2.40 Schrader Tube, 1-Pack | One compact tube for emergencies |
| Want to check fit by code | YunSCM 20 x 2.125-2.40 (54/64-406) Bike Tubes, 2-PCS | Prints 54/64-406 to match your sidewall |
| Fresh tires, short local loops | YunSCM 20 x 2.125-2.40 Schrader Tube, 1-Pack | A single spare is enough for short rides |
Two-Pack vs Single Tube
- Two-pack
- The 54/64-406 pack gives a spare for the next flat and a printed code to verify fit. It takes more basket room, and costs a little more up front.
- Single tube
- The one-pack is the lightest kit and names 2.35 directly. It covers one flat only, and prints no ETRTO code, so you must trust the width list.
Most riders of a wide-tire trike should default to the two-pack unless basket space is tight.
For High-Volume Cushion Trikes Specifically
- Look for
- A band that covers 2.35, a short 32mm valve, and a printed ETRTO code to match your sidewall.
- In this comparison
- The 54/64-406 two-pack matches all three. Fit it with a little air first and an even bead to avoid a pinch.
When to Spend More
- Spend more if
- You carry cargo on a wide tire or ride rough paths often. Neither tube states a thicker wall, so pair them with correct pressure and a rim strip check.
- Save if
- You ride short paved loops. The single YunSCM tube covers a flat for the lowest outlay, and the two-pack adds only a small premium.
Frequently Asked Questions
Does a 20 x 2.35 tire fit a 2.125 to 2.40 tube?
Yes. 2.35 sits in the upper half of that band, so the tube stretches a little more than for a 2.125 tire. Both YunSCM tubes here name 2.35 directly.
What is 60-406?
It is the ETRTO code for a 2.35 tire: about 60 millimeters wide on a 406 millimeter bead seat. The tube band of 54/64-406 contains it, so the codes match.
Can I use a 1.75 to 2.125 tube in a 2.35 tire?
No. That tube is too narrow for a 2.35 casing and would stretch past its range and thin out. Use a 2.125 to 2.40 band instead.
How do I stop the tube folding in a wide tire?
Add a little air before seating the tire so the tube holds shape. Then work the bead on evenly and inflate slowly while checking the tire sits centered on the rim.
What pressure suits a 2.35 tire?
Follow the range printed on the tire sidewall, since wide casings run lower than slim ones. Lower pressure gives cushion, but cargo needs a higher setting to avoid rim strikes.
Bottom Line
For a 20 x 2.35 trike tire, the YunSCM two-pack is the better default thanks to its printed 54/64-406 code and a spare tube included. The single YunSCM tube suits a minimal basket. Add a little air before fitting, and check the sidewall code against the tube first.
