Activa Tyre Size for 6G, 5G, 4G and 3G

Activa tyre size by generation, front and back

So the Activa 6G front tyre size is 90/90-12 and the Activa 6G back tyre size, also called the rear tyre size, is 90/100-10. For the Activa 5G, the front tyre size and the back tyre size are the same 90/100-10, as they are on the 4G and 3G.

Activa wheel size in inches

The figure after the dash gives rim diameter, measured in inches. That makes the Honda Activa wheel size 12 inch up front with a 10 inch rear on the 6G, while earlier generations use 10 inch rims on both ends. The larger front wheel on the 6G rides craters and rough tar more calmly, and stays steadier at speed, while the small rear wheel keeps the storage space under the seat.

What 90/90-12 54J and 90/100-10 53J mean

• 90: tread width, 90 mm.
• 90 or 100: aspect ratio, meaning sidewall height in percent of the 90 mm width. The rear sidewall is 90 mm tall, the front about 81 mm.
• 12 or 10: rim diameter in inches. The dash means bias construction, normal for scooter tyres.
• 54 and 53: load index. 54 is 212 kg per tyre and 53 is 206 kg per tyre.
• J: speed symbol, rated to 100 km/h.

When you replace a 6G tyre, keep at least 54J at the front and 53J at the rear. The Activa often carries two adults and shopping, so do not drop below the factory load index.

Tubeless tyre for Activa

The 6G comes with tubeless tyres on tubeless rims. On the 3G and 4G, sources differ on whether a given scooter rolled out with tubes or without them, so look at the sidewall: tubeless rubber has that word moulded into the sidewall. A tubeless tyre needs a rim that seals at the bead. Fitting a tubeless cover on an older Activa wheel built for tubes will leak unless the rim is designed to seal. After picking up a nail, a tubeless scooter tyre usually deflates over minutes rather than seconds, so you can reach help. Read more on our tubeless tyre page.

Wider rear tyre on an Activa: worth it?

Owners often ask for 100/90-10 at the back for a fatter look. We advise against it on the Activa. The rear wheel sits close to the body and the silencer, and a wider tyre can rub under load. It also changes the speedometer reading slightly and can make steering heavier. The factory sizes balance grip, mileage and comfort for this scooter, so stay with them. To see the effect of any swap on diameter, try the tyre size calculator.

Activa 110, Activa i and Activa 125: not the same tyres

The Activa 110 tyre size people search for is the 6G size above, since the 6G is the 110 cc Activa on sale now. The Activa i was a different, lighter model, and the Activa 125 tyre size page covers the bigger engine scooter. If you are unsure which model you have, the size moulded on your current tyre is the quickest answer.

When to replace Activa tyres

Change a scooter tyre once its grooves are level with the little wear markers, or once the rubber starts to crack. Expect the back one to go first: it puts power down and holds most of the load. Read the week and year code on its side as well; old tyres lose grip in the rain even with tread left.

Pressure for each generation is on Activa tyre pressure, and front bearings are on Activa front wheel bearing number. Other two wheelers are listed in the bike tyre size hub or the Jupiter tyre size page.
