Children's 12x1.75 Stiff Bead Bike Tyre / ETRTO 44-203

How to measure tire wear?

To measure the wear on your tyres and to know when they need replacing, you need to inspect the tread. The tread comes into direct contact with the ground you are cycling on and therefore determines your tyre's performance.



A tyre needs to be replaced when the centre knobs are worn down to the same height as the side knobs.

How to disassemble a tire?

To remove your tyre, deflate the inner tube until no more air comes out.

Then separate the tire from the rim with a tire lever.

How to fit a tyre

Make sure the arrow on the sidewall is pointing in the direction of travel.

To put your tyre back on, place the bead (the rigid part that determines the shape of your tyre) on the rim.

Once you have done this, inflate your inner tube by approximately 30% before fitting it to the rim (inflating it beforehand reduces the risk of pinching the inner tube).



Next, fit the second bead to the rim, starting at the opposite side to the valve.

How to inflate your tyre correctly

Inflate the tire with caution. The recommended pressure is indicated on the side of your tyre as well as on its product sheet (available online).

Also, before each outing, make sure that your tyres are at the correct pressure for your ride.

The professional's advice

During inflation, it is important to obtain the right pressure depending on the terrain and especially depending on the weather.

When riding in rainy weather, lower the tyre pressure to increase the tyre's grip.

On the other hand, if you drive in dry weather, you can increase the pressure.
