    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.

    • Not Good

      09/07/2018
      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
    • 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.
