How to Find the Right Tyre Size for Your Electric Scooter

If you've ever gone looking for a replacement e-scooter tyre and been met with a wall of confusing numbers like "10x2.5" or "80/65-6," you're not alone. Electric scooter tyres don't follow one universal sizing standard, and getting it wrong means a tyre that doesn't fit, doesn't seat properly, or throws off your scooter's handling.

This guide walks you through exactly how to find your correct tyre size, so you can order once and get it right.

Why Getting the Size Right Matters

A tyre that's even slightly the wrong size can cause more problems than it solves:

• It may not fit the rim at all, or only fit loosely enough to be unsafe.
• Fender and frame clearance changes, which can cause rubbing at speed or when turning.
• Ride quality and range shift — a taller or wider tyre changes your effective wheel diameter, which can throw off your speedometer and reduce range slightly.
• Returns are a hassle. Ordering the wrong tyre means paying return shipping and waiting longer for the right one to arrive.

Taking five minutes to measure properly up front saves you all of this.

The Two Sizing Systems Explained

E-scooter tyres are sized using one of two systems, and it's easy to mix them up.

Inch-based sizing (e.g. 10x2.5, 8.5x2) This is written as diameter x width, both in inches. A 10x2.5 tyre has a 10-inch outer diameter and is 2.5 inches wide. This is the most common format for scooter tyres and is usually printed clearly on the sidewall.

Metric/profile sizing (e.g. 80/65-6, 90/55-6.5) This looks more like a moped or motorcycle tyre size. It's read as width(mm)/profile-rim diameter(inches). So 80/65-6 means the tyre is 80mm wide, has a profile (sidewall height as a percentage of width) of 65%, and fits a 6-inch rim. This format is common on performance and off-road style scooters.

Neither system is "better" — they're just different manufacturing conventions, and which one your scooter uses depends on the brand and model.

How to Measure Your Current Tyre

Step 1: Check the sidewall first. Almost every tyre has its size moulded or printed directly onto the rubber. Look for a sequence of numbers like the examples above — this is the fastest and most reliable way to confirm your size, and it's always our first recommendation.

Step 2: If the markings are worn off or unreadable, measure manually:

• Outer diameter — lay the wheel flat and measure straight across the tyre, edge to edge, through the centre.
• Width — measure across the tread at the widest point of the tyre.
• Rim diameter — measure the metal rim itself, not the tyre, from edge to edge through the centre.

Step 3: Compare to known sizes. If your measurements come out close to a standard size (for example, close to 10 inches diameter and 2.5 inches wide) but not exact, go with the standard size — small manufacturing variances are normal and tyres are built with a small amount of flex.

Tube Type or Tubeless — How to Tell

This matters as much as getting the size right, since the two aren't interchangeable without extra parts.

• Tubeless tyres usually have "tubeless" printed on the sidewall, and the rim will have a valve stem moulded directly into it, with no visible seam where a tube would sit.
• Tube type tyres have a separate inner tube inside them, with the valve poking through a hole in the rim. If you can see a distinct valve stem that looks like it's a separate piece pushed through the rim, you're running tube type.

If you're not sure, check your scooter's original spec sheet or take a clear photo of your current wheel — our team can help confirm from there.

Common Models and Their Tyre Sizes

Here's a quick reference for some of the most popular brands we stock parts for. Always confirm against your sidewall markings where possible, since manufacturers sometimes change tyre specs between model revisions.

Still Not Sure? Here's What to Do Next

If you've checked the sidewall, measured your wheel, and you're still not confident on sizing, don't guess — a wrong-size order costs you time and shipping either way. You can:

• Contact our team with your scooter's make and model (or a photo of your current tyre) and we'll confirm the right size before you order.
• Find a workshop near you using our workshop finder if you'd rather have a professional check and fit it for you.
