Best 20 x 4 Bicycle Tires for Tricycles
Two 20 x 4.0 tire packs fit this size, and the call is between a reinforced all-terrain pair and a foldable one.
Updated · 2 min read · 2 products evaluated
A 20 x 4.0 tire is the widest common size on a 406 mm rim, around 100 mm across, built for snow, sand and heavy electric adult trikes. That much air volume cushions bad pavement and spreads weight on soft ground, and it needs a rim wide enough to hold it.
Two packs in this group are real 20 x 4.0 tires, and both come as pairs, which suits a trike's rear axle. Focus on tread, folding bead and what each pack asks you to buy separately.
Short answer
The Ultraverse 20 x 4.0 pair is the pick for trikes that need a reinforced sidewall and all-terrain directional tread on a rear axle. The BALINGE 20 x 4.0 foldable pair is the alternative, with a bead that can fold for storage and levers in the box. Plan on a matching 4.0 tube for either.

Ultraverse 20 x 4.0 Fat Tire Pair
Two fat tires with a robust sidewall and directional all-terrain tread, sized for a trike's rear axle.
Best for
Trikes riding pavement and trail
Why we like it
Ultraverse packs two 20 x 4.0 fat tires with a reinforced sidewall and a directional herringbone-style tread meant for both street and trail. Matching tires in one box are the natural fit for a rear axle.
Against BALINGE's pair, it leans on sidewall strength and a front-or-rear label rather than a folding bead, so it is not the one to carry as a spare. It is also heavy to haul. It suits riders who want one durable set for mixed surfaces, with the caveat that no pressure range is given and the tread hums on smooth pavement.

Best Foldable Pair2 of 2
BALINGE E-Bike 20 x 4.0 Foldable Fat Tires
A pair of 20 x 4.0 tires with a foldable build and levers in the box.
Best for
Trikes needing a stowable spare pair
Why we like it
BALINGE sells two 20 x 4.0 e-bike tires with two tire levers in the pack, and the maker states the tire can fold without damage for storage. The tread is described for rolling speed and low drag on hard-pack or paved ground.
Compared with Ultraverse, the folding build and included levers make it easier to carry, while the tread is less aggressive. It also suggests replacing both tires at once, which suits a trike. It fits riders on mostly pavement and light trail. The caveat is that mountain and snow use are less clearly supported than with a lugged tread.

How We Chose These 20 X 4 Bicycle Tires for Tricycles
- True 4.0 tires
- Only tires labeled 20 x 4.0 qualified. Tubes are sold separately and cannot replace a worn tire, so match the tube size to the tire you choose.
- Matching pair
- Trikes with a two-wheel rear axle benefit from identical tires, so packs of two ranked above singles. Both picks arrive as pairs.
- Tread and use
- We judged tread against real trike surfaces, giving credit to lugs for soft ground and to low-drag patterns for pavement.
- What you still buy
- Neither pack includes tubes, so we noted this and pointed readers to matched 20 x 4.0 tubes instead of treating the tire as a complete swap.
What to Look for in a 20 X 4 Bicycle Tires for Tricycles
Rim width for a 4.0 tire
A 4.0 tire is about 102 mm wide, and it needs a rim wide enough to hold its bead without bulging. A narrow rim lets the casing roll under load, which hurts handling.
Look up your rim's inside width in the wheel's specs, or measure it with calipers, and check it against the tire maker's width guidance before buying.
Sidewall strength for trikes
A trike's rear tires carry constant load without leaning, so sidewalls flex the same way every revolution. Reinforced sidewalls resist scuffs from curbs and cracking from age.
Look for words like reinforced or robust, as Ultraverse uses, and inspect sidewalls for cracks when buying a stored spare.
Foldable bead and spare use
A foldable bead trades the stiff steel wire for a flexible one, so the tire folds into a loop. That is useful for carrying a spare in a car or bag.
For a 4.0 tire, the fold is still bulky, so measure your storage space. A steel bead holds its shape but cannot be stowed.
Tube match and levers
A 4.0 tire needs a tube that stretches to fit it, such as a 20 x 4.0 Schrader. An undersized tube folds, and an oversized one wrinkles.
BALINGE includes levers, while Ultraverse does not, so check your toolkit before you start. Seat the tube with a little air and check the bead line.
How to Choose
By Surface
| Situation | Our pick | Why |
|---|---|---|
| Mixed pavement and trail | Ultraverse 20 x 4.0 | Directional tread and reinforced sidewall |
| Mostly hard pack | BALINGE 20 x 4.0 Foldable | Low-drag tread suits firm ground |
| Spare in a vehicle | BALINGE 20 x 4.0 Foldable | Foldable build stows more easily |
Steel Bead vs Foldable
- Reinforced pair
- Ultraverse emphasizes a robust sidewall and heavy-duty build, which suits tires that stay mounted. It is bulky to carry as a spare.
- Foldable pair
- BALINGE states its tire folds without damage, which suits stowing. A lighter tread suits pavement more than deep soft ground.
Choose the Ultraverse pair for tires that stay on the trike.
For Heavy Electric Trikes Specifically
- Look for
- A reinforced sidewall, a pair for the axle, and a stated e-bike suitability so the casing can handle torque and load.
- In this comparison
- Ultraverse leads on sidewall strength, and BALINGE is described for e-bike use. Either suits a heavy trike, with the Ultraverse stronger on rough ground.
When to Spend More
- Spend more if
- You ride rough trails or haul loads. The Ultraverse pair's reinforced sidewall gives more margin, and its warranty claim adds confidence.
- Save if
- You ride firm surfaces and want a stowable spare. BALINGE's folding pair with levers covers that without the heaviest build.
Frequently Asked Questions
Do these tires include inner tubes?
Neither pack includes tubes with the tires, so plan on buying a matching 20 x 4.0 tube. Choose a Schrader-valve tube sized for 4.0, and add tire levers if you do not own a set.
Can I mix a 4.0 tire with a smaller front tire?
Some trikes use different sizes front and rear, but each wheel needs the size that suits its rim. Check each sidewall and rim width, and only swap in a 4.0 tire where the frame has clearance.
Are fat tires slower on pavement?
They have more rolling drag than slim tires, but on a trike at walking or cycling pace the difference is modest. Lower pressure adds cushion, and a smoother tread reduces hum on hard ground.
What pressure should I run?
Use the range printed on the sidewall as the ceiling. Neither pack gives a pressure number here, so mount the tire and read the sidewall. Start low for comfort and raise it until the tire holds its shape.
Should I replace both rear tires together?
Yes, on a trike with two rear tires, replacing the pair keeps grip and height even. A mismatched pair can make the trike drift when braking. BALINGE even recommends replacing both tires together.
Bottom Line
Two real 20 x 4.0 tire packs fit this size. The Ultraverse pair suits trikes that need a reinforced sidewall and all-terrain tread, while the BALINGE foldable pair suits pavement and stowable spares. Plan on matched 20 x 4.0 tubes for either, and replace both rear tires together.
