Everything You Need to Know About Electric Bike Tires

Your ebike tires are the connection between you and the road, keeping you safely on the ground. That's why it's so important that your ebike tires are perfectly adapted to your ebike model and the riding conditions.

This is especially true for long range electric bikes, where tire performance can significantly impact your ride's efficiency and comfort. Here you can find out what you need to pay attention to with ebike tires: the right material, tire pressure, tire width, and tire thickness play a crucial role. Ensuring your tires are optimized for your long-range electric bike can help you achieve the best possible performance and longevity on extended journeys.

The Right Tire for Your E-Bike

The right e-bike tires are very important if you want to get the most out of your e-bike. They carry you (weight + e-bike + luggage), participate in braking maneuvers, provide you with the necessary grip when accelerating and ultimately buffer against curbs or potholes. E-bike tires have reinforced sidewalls, so they ensure that you always have good grip at higher speeds.

E-bike Tires vs. Normal Tires: What's the Difference?

E-bikes are heavier and travel faster due to the battery and display, so the forces released when braking and turning are completely different from those on normal bikes. It's no surprise, then, that e-bike tires are different from normal bike tires.

More stable and wider: This makes them the best weight carriers and ensures a high level of comfort and better control.

Grippier profile: This ensures safety on slippery roads, in bends, and uphill.

Greater puncture protection: Fewer defects despite higher loads.

Greater braking power and shorter braking distances.

Tire Models

Even within the same tire, there are differences between individual products. Large differences can be found, especially in the profile. First of all, you should clarify which type of tire is suitable for your e-bike. We have sorted out the most important variants for you.

Clincher

This type of tire is currently the most common. If the product description does not say otherwise, it is this type of tire. Clincher tires have separate wire rings or wire bundles on the inner edge of the tire and are placed on the rim.

They are covered with a rubber compound, which forms a bead. To keep this bead in place, the inner side of the rim flange has a corresponding profile. The outer tire is placed around the inner tube and clamped into the rim flange, which fixes it stably and firmly.

Folding Tires

Folding tires are a form of clincher tire. The bead wire here consists of a more flexible strand of aramid. This allows the tire to be folded up and stored away. Folding tires usually weigh 50 to 100 grams less than wire tires.

Tubular Tires

Even with tubular tires, the outer tube is placed around the inner tube. However, to connect it, it is glued to the rim. This means that the tire can be driven at high air pressures and generally has lower rolling resistance.

Tubeless Tires

Tubeless tires are known to be less prone to flats. In contrast to the other four variants, the tube and the sheath are not separate from each other; they are the same product. This type of tire is mainly used by electric mountain bikers.

Advantages of the Tubeless System

• Puncture safety
• Better handling due to lower air pressure (suspension)
• Lower running resistance (less friction due to the internal hose)
• Lighter weight (usually; not always guaranteed with older and cheaper systems)

Disadvantages of the Tubeless System

• Entry barrier: installation is more laborious, the rim must be adapted to the new tire type
• Higher maintenance costs: sealing latex must be replaced approximately every 3-6 months
• Fewer product options：Usually more expensive: tubeless tires have a sealing latex inside that crystallizes and seals small holes in milliseconds. If the hole is not repaired, the air escapes more slowly than with a conventional tire. In addition, tubeless tires have less rolling resistance.

Balloon Tires

Balloon tires are usually 50 to 65 mm (2 to 2.5 inches) wide and can be driven at a lower air pressure of around 2 bar. This provides more cushioning for the driver and is therefore more comfortable.

Self-Repairing Bicycle Inner Tube

The tube is filled with a gel that seals the hole. Disadvantages: The gel only retains its elasticity for 6 months. After that, it can no longer prevent holes.

Why Do E-Bikes Have Special Tires?

Weight

Due to the motor and the battery, e-bikes weigh much more than regular bikes. That's why the load on the tires is greater. Therefore, it makes sense to use slightly wider tires, which usually offer better puncture protection, more comfort, and better grip.

Speed

The average speed of e-bikes is also higher. Therefore, it is very important that the tires have good grip and give the bike stability, especially when turning. In addition, changing tires on e-bikes is slightly more complicated. Their weight makes them more difficult to manage, and if you have a rear-wheel drive, you have to remove the rear wheel with more effort.

E-bike Tire Sizes

E-bike tire sizes are typically described using two numbers: the diameter of the wheel and the width of the tire. You'll usually see these numbers printed on the sidewall of your tire.

The diameter is usually measured in inches (like 20", 24", 26", 27.5", or 29") or sometimes in millimeters (like 700C, which is roughly equivalent to 29"). The width is usually measured in inches (like 1.5", 2.0", 3.0", or 4.0") or millimeters (like 23mm, 35mm, or 42mm).

Common Diameters

• 20 inch: Often found on folding e-bikes, smaller cruiser e-bikes, and some cargo e-bikes. They offer quick acceleration and a compact size.
• 24 inch: Used on some smaller adult bikes, cruiser bikes, and utility e-bikes, providing a good balance of maneuverability and smooth rolling.
• 26 inch: A very common size for electric mountain bikes, fat tire e-bikes, and cruiser e-bikes. It offers a good mix of agility and rollover ability.
• 27.5 inch (or 650b): Popular on modern electric mountain bikes and some gravel or hybrid e-bikes. They provide a good balance between the agility of 26" and the momentum of 29".
• 29 inch (or 700C): Standard on many electric road bikes, commuter bikes, and larger electric mountain bikes. They roll over obstacles easily and maintain speed well.

Common Widths:

• Narrow (23mm - 32mm): Typically for road e-bikes, prioritizing speed and efficiency on pavement.
• Medium (35mm - 50mm or 1.5" - 2.0"): Common for hybrid, commuter, and some touring e-bikes, offering versatility across different surfaces.
• Wide (2.0" - 3.0"): Found on electric mountain bikes and some more capable hybrid e-bikes, providing increased traction and comfort on rougher terrain.
• Extra-Wide (3.8" - 5.0"+): These are fat tires, designed for maximum flotation and grip on soft surfaces.

Matching the tire size to your rim size is crucial, and there are international standards (like ISO or ETRTO) that provide precise measurements to ensure compatibility.

What to Consider with E-Bike Tires?

E-Bike Tire Pressure

The most common cause of flat tires: too low air pressure. If the pressure in an e-bike tire is too low, so-called pinch creases will appear. The inner tube can then get stuck between the rim and the tire, and a small hole will appear.

In addition to pinch creases, poorly inflated tires also increase rolling resistance. This can cause the tire to wear out faster in the long run. It is therefore very important for e-bikes and all other bicycles to always have the correct air pressure.

Why do tires lose pressure at all?

Conventional bicycle tires also lose air when riding or standing – regardless of whether they are damaged or not. The weight of the wheel presses on the tire, and this alone allows the air to slowly escape. So our advice: check the air pressure regularly, especially before long rides.

A potential savior appeared at Eurobike 2019: The AirWinder Le Formidable tire is designed to solve this problem by inflating itself while riding. Sounds good? You can find a whole article about new tires at.

Ebike Tire Size

eBike tire size isn’t just about whether it fits the rim – it also changes how the bike rides, how stable it feels, and how much battery power you use. Most e-bikes use common diameters like 20", 26", 27.5" or 28"/700c, but the width can vary a lot, from around 1.75" on city bikes to 4.0" or more on fat-tire models. Narrower tires are usually lighter and roll faster on smooth pavement, while wider tires give you more comfort, grip, and control on rough roads, gravel, or off-road paths.

When choosing an eBike tire size, always check the ETRTO markings (for example, 50-584) on the sidewall or in your bike’s manual to match the correct diameter and width for your rim. Make sure there is enough frame and fork clearance for a wider tire if you want more comfort, and remember that very large, heavy tires can slightly reduce range because the motor has to move more rotating mass. The best eBike tire size is the one that fits your frame safely, matches your terrain, and balances comfort, grip, and efficiency for how you actually ride.

Tire Age

Even if the tires are not moving, they age under UV radiation. They become dry and brittle. Therefore, do not leave your bicycle or e-bike in the hot sun, but keep it in a garage or in a cool place. Likewise, rain and cold are not good for the life of the tire. Therefore, a roof makes sense.

Rolling Resistance

For e-bikes, rolling resistance affects the range. The more resistance the tire offers, the more power the drive and therefore the battery must provide. The profile of the e-bike tire has a significant impact on rolling resistance.

"The continuous tread strip in the middle is beneficial," explains Christian Wurmbäck from Continental. "This prevents the profile from deforming while driving, which would lead to drag and power loss." Extending battery range, saving power, and taking longer trips - there are really only benefits to focusing on low rolling resistance when choosing tires.

ECE R75 Approval

The S-Pedelec requires tires that are ECE R75 approved. When buying tires for an S-Pedelec, you should look carefully. Otherwise, you might end up with tires that are not legally allowed to be installed on an S-Pedelec. In addition, the tread depth requirement for S-Pedelec tires is 1 mm. That's why S-Pedelec drivers must check their tires for wear more often and, if in doubt, replace them.

Puncture Protection

Changing tires is a bit complicated, especially for e-bikes. The weight of a pedelec alone makes changing them more complicated. Changing tires in the middle of a trip can be inconvenient and is best avoided.

A quick change is practically impossible, especially with heavy models. Therefore, e-bike tires should have good puncture protection and not deflate from the smallest puncture.

Tire manufacturers design various rubber compounds and fabric layers to improve puncture protection. For example, with its Marathon model, Schwalbe has developed a tire that cannot be flattened and can even withstand rice nails. Before the journey begins, there are aids to minimize the risk of a flat tire.

Puncture Protection Tape

Place the puncture protection tape between the hose and the jacket before the ride. Made of a stronger plastic than the rubber jacket, the tape is designed to prevent holes. The SWR Market Research video "Bicycle and e-bike buying tips" shows: glass is not a problem with puncture protection tape, rice nails are.

Are There Differences in E-Bike Winter Tires?

Yes - for cold, slippery seasons, there are special e-bike winter tires that can get you from A to B more safely. They have a finer profile, different rubber, and better grip, so you have good grip and safe, short braking distances even on slippery, snowy, and icy terrain.

Correct E-Bike Tire Pressure

The correct tire pressure for an e-bike depends on the tire width; this is written on the tire itself, for example, if your e-bike tire is 1-3 cm wider, the tire pressure should be between 4 and 5.5 bar (the permissible pressure range is marked on the tire sidewall and the air pressure can be measured with a pressure gauge).

The rule of thumb is: the wider the tire, the less pressure is required. You probably know this from narrow racing tires, which always have to be inflated very hard in order to ride smoothly and quickly.

Higher tire pressure generally results in lower rolling resistance and thus better protection against punctures. Lower tire pressure can be pleasant because it provides more comfort. In addition, lower tire pressure provides more grip and control, which is especially effective when the road is slippery in rain or snow.

Why Low Tire Pressure is Bad for E-Bikes

Similar to cars, e-bikes are bad if the tires are not inflated enough. Because when the tire is deflated, the contact area of the tire surface with the ground is larger, which creates more friction. This means that more energy is needed to fight this friction, and your e-bike battery drains faster. A properly inflated e-bike tire is strong enough for you to ride comfortably, and it won’t wear out as quickly. With the correct tire pressure, your e-bike tires will last longer.

How Do You Know Your E-Bike Tire Pressure is Bad?

If you feel like you’re riding against a headwind, your tires may need more pressure. So bring a pump! If you feel wobbly while riding, your tires may be overinflated. Just let some air out! With the correct air pressure, not only will your tires last longer, but they’ll also be less likely to blow out. So you’ll be safer on the road.

Check Your E-Bike Tires Regularly

You can easily check the condition of your e-bike tires yourself: if you notice a lot of brittle cracks in the tire tread, it’s probably that you’ve been riding for too long with too low tire pressure. The ultimate lifespan of your tires depends on three factors:

• How heavy is your e-bike?
• What does it have to carry?
• Are your e-bike tires always at the correct pressure?
• What surfaces do you ride on?

Common Ebike Tires Problems and Solutions

Got issues with your electric bike tires? Knowing how to troubleshoot common problems can keep you rolling smoothly. Here are some frequent issues and their solutions.

Proper Maintenance of E-Bike Tires

Maintaining your e-bike tires is crucial to ensure a smooth and safe ride. Here are some tips on proper maintenance:

Inflation

Regularly check your tire pressure. For example, if your e-bike tires are rated for 40-60 PSI, keeping them at the higher end can improve rolling efficiency and battery life. However, lower pressure can enhance grip and comfort on rough surfaces. Using a reliable gauge like the Topeak SmartGauge D2 can help maintain the correct pressure.

Inspection

Make it a habit to inspect your tires for any signs of wear and tear. If you frequently ride on rough terrain, check for cuts, cracks, and embedded objects like glass or small stones. Catching these issues early can prevent flats and other problems. For instance, noticing a small cut on your rear tire before it becomes a big problem can save you from a sudden flat.

Rotation

If you notice uneven wear on your tires, consider rotating them. This means swapping the front and rear tires to even out the wear pattern. Rotating tires every few months can extend their lifespan and ensure more consistent performance. For example, if your rear tire is wearing faster, switching it with the front can help balance the wear.

Cleaning

Keep your tires clean by washing them with mild soap and water. This removes dirt and debris that can wear down the rubber over time. Avoid using harsh chemicals that might damage the tire material. For instance, a simple wipe down with a sponge and soapy water can keep your Schwalbe Marathon tires in good shape.

Storage

If you’re not using your e-bike for an extended period, store it in a cool, dry place away from direct sunlight. Prolonged exposure to UV rays can degrade the rubber and cause your tires to crack. For example, keeping your e-bike in a garage or shed rather than outside can significantly extend the life of your tires.

Maintaining your e-bike tires properly not only ensures a smoother ride but also extends their lifespan, saving you money in the long run. Regular checks, proper inflation, and keeping them clean are simple steps that make a big difference.
