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 put your tyre back on
    To put your tyre back on, first start by placing one side of the tyre into 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, place 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. On the other hand, when riding in dry weather, you can increase the pressure for better performance.

  • Cracking tyre for the price

    29/11/2018
    Chris (United Kingdom)
    Used for More than 1 year
    I've had these for ages on my Rockrider and have finally had to replace it after wearing it down.
    Bear in mind I only really do on-road cycling but I do this in all weathers and I have been very impressed with this tyre. I certainly will buy again when the front wears out.
    The only downside is they are a nightmare to get on and off. I think I will have to upgrade my tyre levers!
    That being said, they last a long time and grip pretty well considering of the amount of tred you have.

  • Not good for roads even

    Used for 3 to 6 months
    Got punctured twice in last 15 days while I was on city roads.
    Response of the brand
    I'm sorry to read that you've had a few punctures recently. As a fellow cyclist I feel your frustration. Most punctures either occur due to the tyre pinching the inner tube or because a foreign object such as a thorn/nail/glass/flint has lodged itself in the tyre. It could also be that the innertube is compromised. It is hard to say why this happened on these two occasions. As long as the tyre pressure is correct, the tyre has no hidden foreign objects stuck (which can be hard to spot) and it is mounted correctly onto the rim then most punctures can be avoided...but you never know. Sometimes I get none for months then suddenly three during the same ride!
    If you ride a lot in town, it is also worth investing in self sealing innertubes which work very well (as long as the hole is not too large).

  • Blew up

    08/09/2017
    jon (United Kingdom)
    Used for 1 week or less
    The tyre didn't even last 24 hours. It blew up whilst my son was cycling in front of our house. I glad my son didn't have any injury, but the fact that it just spontaneously blew up is simply a sign of a bad product.
    Response of the brand
    I hope that your son is OK. The noise must have been a shock.
    I am assuming the tyre was pumped up to the correct pressure and seated on the rim correctly prior to inflation, therefore the tyre may well be faulty. Please return it to your local store for inspection who will then replace of refund the tyre.

  • Not Good

    Aashish (India)
    Used for 3 to 6 months
    It got punctured 5-6 time in last 3 months. the tyre pressure reduces overnight. do not have any confidence on the product now
    Response of the brand
    Hello Aashish, 

    Thank you for taking the time to give us your review. Apologies for the bad experience with the all-terrain tyre. Please note that punctures are unavoidable on a bicycle. It depends on the route taken. If we take a route with materials that cause punctures, then a puncture is unavoidable with any tyre. A tyre that does not wear out, has no cracks after many miles on it is a good tyre, and it can have many punctures in while doing those miles. As a solution to the problem of the deflations please try a new inner tube. If you are riding in complete off-road conditions with thorns etc I would recommend a tire liner. I remain available if you have more questions. 

    Thanks
    Deepak
