Pump your e-bike tyres to a pressure inside the range printed on the tyre sidewall, check them with a gauge at least once a month (weekly is better), and adjust within that range for load, surface and weather: firmer for heavier loads and smooth roads, a little softer for grip on gravel and in the wet. There is no single right number for every e-bike, because the right pressure depends on the tyre and on how much weight sits on it.
This guide is for anyone who rides an e-bike, or looks after one for someone else.

Why does tyre pressure matter on an e-bike?
Because the air in your tyres carries you, your bags and the e-bike itself, and the amount of air changes how the e-bike rides, grips and wears. Schwalbe, the tyre maker, puts it simply: only with enough air pressure can the tyre carry the bike (Schwalbe on tyre pressure).
Get it right and an e-bike rolls easily, corners predictably and shrugs off small bumps. Get it wrong and you feel it:
- Too soft: the e-bike feels sluggish and heavy to steer, the tyre can squash onto the rim over a bump and pinch the tube, and the sidewalls wear and crack early.
- Too hard: the ride turns harsh on rough paths and the tyre has less grip, especially on loose or wet ground.
On an e-bike the motor hides some of that sluggishness, so soft tyres are easy to miss without a gauge.
What is the right tyre pressure for my e-bike?
The right pressure is anywhere inside the minimum and maximum printed on the side of your tyre, set for your load and the riding you do. Schwalbe says it's not possible to give one general pressure for a specific bike or tyre, and that you should never go above the maximum or below the minimum marked on the tyre.
Where you land inside that range follows a few plain rules from the same Schwalbe guidance:
- Wider tyres run lower pressure than narrow ones, without giving up much in rolling or puncture resistance.
- Small diameter wheels, such as those on folding bikes, need a little more pressure than you might expect from their width.
- More weight needs more pressure. The load on the tyre matters most, and it comes mainly from the rider and the luggage.
So find the range on your sidewall first. It is moulded into the rubber, usually near the tyre size, and if your rim also carries a pressure limit, stay under the lower of the two. The Miniwave folding e-bike has 20 x 3.0 inch puncture-resistant tyres; read the range on its sidewall, or ask us and we'll show you where to look.
How does load change the pressure you need?
The heavier the load, the firmer the tyre needs to be. Schwalbe explains that the right pressure depends largely on the weight on the tyre, mainly the rider and luggage, while the bike's own weight plays only a minor part.
In practice:
- Riding light: sit toward the lower half of the sidewall range for comfort and grip.
- Commuting with a loaded rack or shopping: move toward the upper half, especially in the rear tyre, which carries the rack and more of your weight.
- Carrying more on some days than others: check and top up before the heavy trips rather than setting one pressure and forgetting it.
The Miniwave has a rear rack welded into the frame, rated to 68 kg within a 155 kg maximum total load (rider plus cargo). If you use that rack for groceries or a bag of tools, a firmer rear tyre stops it squashing and feeling vague.
Should you change pressure for different surfaces?
Yes, within the sidewall range. Schwalbe sums up the trade off: the higher the pressure, the lower the rolling resistance, wear and risk of punctures; the lower the pressure, the more comfort and grip.
| Where you ride | Where to aim in the sidewall range | Why |
|---|---|---|
| Smooth roads and bike paths | Upper half | Rolls more easily and resists punctures |
| Mixed streets and shared paths | Middle | A balance of grip, comfort and rolling |
| Gravel, grass and uneven tracks | Lower half, never below the minimum | More grip and a softer ride over bumps |
| Wet roads and painted lines | A little softer than usual | More rubber on the ground for grip |
| Heavy load on the rack | Firmer, especially the rear | Stops the tyre squashing onto the rim |
Change it in small steps on a familiar loop. Once you know a setting for the commute and one for weekend gravel, switching takes a minute with a pump.
Wide tyres give you more room to play with here. If you're weighing up tyre width as well as pressure, see our guide to whether a fat tyre e-bike is right for you.
What about rain and wet roads?
Ease the pressure off slightly, staying inside the sidewall range, and ride for the conditions. Lower pressure gives the tyre more grip, which helps on wet bitumen, painted lines and metal grates.
Don't go soft enough to pinch the tube on a pothole hidden under water, and top the tyres back up when the roads dry out. Our guide to riding an e-bike in the rain covers the rest of a wet ride, from puddles to drying the battery.
How does tyre pressure affect punctures?
Correct pressure is one of the simplest ways to avoid flats. Bicycle Network explains that a pinch flat happens when tyre pressure is too low, so the tyre compresses on a bump and pinches the tube against the rim, and that keeping the right pressure is one way to avoid it (Bicycle Network puncture repair guide).
Schwalbe adds that tyres are less prone to punctures at higher pressure, and that a tyre kept permanently underinflated wears early, with cracked sidewalls the typical result.
Puncture-resistant tyres, like those on the Miniwave, help against glass and thorns working through the tread. They still need the right air inside them to avoid pinch flats and sidewall wear.
How do you check e-bike tyre pressure with a gauge?
Use a pressure gauge or a floor pump with a gauge, not your thumb. Schwalbe notes that all tyres feel hard and well inflated from about 2 bar, so a squeeze tells you very little about whether you're near the top or bottom of the range.
- Find the range on the tyre sidewall and decide where you want to be in it.
- Check before you ride, when the tyres have been sitting, so the reading is consistent from week to week.
- Take off the valve cap. On a Presta valve, also unscrew the small knurled nut at the tip.
- Press the gauge or pump head on straight and firmly. A hiss means it isn't sealed; take it off and try again.
- Read the pressure, then pump in air or press the valve to let some out, a little at a time.
- Check again once you're close, and stop inside the range.
- Close up. Retighten a Presta nut, refit the cap, and do the other tyre.
How often? The NSW Government lists checking tyre pressures as a weekly job for a bicycle or e-bike, and checking tyres for wear or splits as a monthly one (NSW Government guide to maintaining your bicycle or e-bike). Schwalbe's minimum is once a month. A weekly check with the rest of your e-bike's routine is easy to remember; our e-bike maintenance schedule puts it alongside the brakes, chain and battery.
Which valve does my e-bike have?
Look at the valve stem poking through the rim. Schwalbe describes three classic types (Schwalbe on bike tyre valves):
- Schrader (car valve): the same wide valve as on a car tyre, with a spring loaded pin in the middle. It fills easily from most pumps, and from a service station air line.
- Presta (Sclaverand): slimmer, at 6 mm instead of 8 mm, with a small knurled nut at the tip that you unscrew before pumping. The thin pin bends easily, so attach and remove the pump head gently.
- Dunlop: common worldwide on everyday bikes. Traditional Dunlop valves don't let you check the pressure with a gauge, so ask your bike shop about a valve core that does.
Some pump heads fit both Schrader and Presta valves and some fit only one, so check your pump matches your valve before you need it on the side of the road.
Frequently asked questions
Can I use a service station air line on my e-bike tyres?
Only on a Schrader valve, and carefully. Air lines push a lot of air quickly into a small bike tyre, so add short bursts and check with your own gauge as you go. A floor pump at home is easier to control.
Why do my tyres go soft when the e-bike is parked?
All inner tubes slowly lose air. Schwalbe says losing about 1 bar a month is normal, and faster at high pressures. If a tyre goes soft within a day or two, look for a slow puncture or a leaking valve.
Does tyre pressure affect my e-bike's range?
It can. CHOICE notes that keeping tyres pumped up helps you get more range from the battery (CHOICE guide to maintaining an electric bike), and the range figures on our Miniwave page note that real range varies with tyre pressure, as well as load, terrain and weather.
Which Ridewave e-bike is easy to keep rolling?
The Miniwave folding e-bike is built around wide, forgiving tyres. It has 20 x 3.0 inch puncture-resistant tyres, an 80 mm front suspension fork with hydraulic lockout and hydraulic disc brakes with 180 mm rotors front and rear. With a 155 kg maximum total load and a rack welded into the frame, it's made to carry a rider and their shopping, and it folds in three steps (frame, stem and pedals) so it can live indoors between rides.

What tyre pressure can't fix
The right pressure won't save a tyre with worn out tread, a cut or bulge in the sidewall, or a valve that keeps leaking. If a tyre won't hold air, or you can see cord or splits through the rubber, have it looked at before you ride on. Your e-bike's own manual and the tyre's sidewall come first for model specific pressures.
Feel the difference in person
Wide tyres at the right pressure are a big part of how an e-bike feels on a bumpy path. Come and ride the Miniwave, and ask us to show you where its pressure range is printed and how to check it at home.
