Woom Off/off Air/up Tyre

With a high volume, these tires not only get a larger contact patch but also provide added stability and damping out of trail vibrations.

This is because they can be run with higher tire pressures, which minimizes rolling resistance. Naturally, the optimal tire pressure is dependent on the rider’s weight and the terrain. But at the same time, a tire run at a lower pressure is able to absorb more bumpiness than a tire at a higher pressure, which further increases comfort over rough ground.

Combined, these tires hit the sweet spot of grip, comfort and rolling resistance to so that kids get a safer and more confidence-inspiring ride that’ll encourage them to play and take on new, fun trails.

How do I know what tire pressure to run?

If there’s one thing to do before your next mountain bike ride, it’s set the correct tire pressure. But, you might cry, what’s correct, and how do we find an individual’s precise air pressure sweet spot for grip, cushioning and stability?

There’s no definitive answer, unfortunately. As mentioned, tire pressure is all about the individual . On the tire’s sidewalls you’ll see the recommended minimum and maximum pressure values, so this makes your baseline window. From here, you consider a number of other factors, like your child’s weight and what sort of terrain, riding, and conditions are on the menu.

To get a stable and comfortable ride, we suggest getting your child on the saddle so that you can tune the tire pressure – with their weight on the bike, look for a very slight tire drop of around 15%. This way, the tire can provide great grip on diverse terrain while nicely cushioning the bike as it conforms to the irregularities of the surface.

Top tip: set the bike up with a fairly high baseline pressure. Ask your child to do a small test loop, including corners, braking and riding over a range of surfaces and bumps. See how the bike behaves and feels, then make small incremental changes until it feels like you’ve found the air pressure sweet spot.

Encourage your child to think about grip and stability. Does it feel a little wallowy and unstable while cornering and at a high speed? Does it feel like it’s bottoming out over roots, rocks or kerbs (i.e. touching the rim)? If yes, add some tire pressure!
