Product feature
  1. How to measure tyre 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 terrain you are cycling on and therefore determines your tyre's performance. A tyre needs to be changed when the centre knobs are worn down to the same height as the side knobs.
  2. How to remove a tyre
    To remove your tyre, first deflate the inner tube until no more air comes out. Once deflated, use a tyre lever to remove the tyre from the rim.
  3. How to fit a tyre
    To put the tyre back on, place one side of the tyre into the bottom of the rim. Next, inflate your inner tube to approximately 30% before putting it into the tyre (inflating it beforehand reduces the risk of pinching the inner tube). Then, insert the other side of the tyre into the rim, starting on the side opposite the valve. Before inflating the inner tube all the way, check to make sure it isn't pinched between the tyre and the rim.
  4. How to inflate your tyre correctly
    Inflate your tyre carefully. The recommended pressure is indicated on the side of your tyre as well as on its product sheet (available online). Before each outing, make sure that your tyres are at the correct pressure for your ride.
  5. Tip from the pros
    When inflating your tyre, be sure to inflate it to the correct pressure for the terrain you will be riding on and especially the weather conditions. When riding in rainy weather, lower the tyre pressure to increase the tyre's traction. When riding in dry weather, you can increase the pressure for better performance.

    David (United Kingdom)
    Used for 2 to 8 weeks
    Superb value and its profile and pattern make it a pretty good all round tyre - impressed so far.
    All-purpose tread effective in mud and wet grass.
    Profile is a bit narrow for loose trails.
  • Top tyre for little money

    Used for 3 to 6 months
    at 11.99 these are top quality tyres run them on county lanes city street and cycle paths as well as off road.Had a lot of heavy rain of late and still give me loads of grip on mud soaked horse trail tracks.So good in fact they if they did one with a blue side wall would put them on my other mtb.
    good all round grip
