Technical Information

How to choose your inner tube
Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means a tyre with a 26 inch diameter and a cross-section width of 2.2 inches. On the sidewall of the tyre you will also find the dimensions in mm expressed in ETRTO international units. For example, 50-559 means the tyre is 50 mm wide with an inner diameter of 559 mm (approx. 26" x 2").
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
What to check before installing your new inner tube
Check the condition of your tyre and replace it if necessary. Make sure no objects are lodged in the tyre. Check the condition of your tyre rim strip. Even slightly bent rim strips can cause punctures. Check that your rim does not have any other issues that could damage your inner tube.
Fitting your inner tube
Watch our video before you start. Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rims. Put the inner tube entirely inside the tyre so that it fits inside the rim. Take care not to pinch the inner tube when fitting.
Mounting the tyre
Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre using a screwdriver or a tyre lever as you risk pinching and puncturing the inner tube.
Inflating the tyre
Inflate your tyre carefully to the pressure recommended by the manufacturer (visible on the sidewall of the tyre in PSI or bars, 1 bars = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
Tip from the pros
To avoid punctures due to the inner tube being pinched, and to get the best performance out of your tyre, we recommend checking your tyre pressure and inflating it if necessary before each ride.

Response of the brand
Hello Punith,

Thank you for taking the time to give us your review. The inner tube usually heals staple pins and smaller punctures. It may not be able to heal nail piercings. I suggest you try a tire liner to reduce the number of punctures.  I remain available for more questions.

26x1.7-2.2 Self-Healing Inner Tube - Schrader Valv
Used for 2 to 8 weeks
I bought a second one of these auto-repair tubes last week for my other tyre.
But after filling the air, just as I was about to put the cap on, I noticed that some air was coming out of the valve. I then checked my other wheel which had this same self-healing tube fixed couple of months before. To my surprise, it also had a similar air leak from the valve. I still used it for a couple of days and the loss of air pressure is not noticeable. I am not sure if this is the way they are designed or whether I got faulty pieces. I am actually confused and hope to check with the store one of the weekends. I've not yet got a flat tyre situation to see the auto-repair in action (or did it happen and it auto-healed and I did not know!!?, which would be cool).

Hello Rajesh, 

Not sure how you noticed that the air is leaking from the valve because if it was so evident the tire would have been flat in a couple of hrs. The fact that it is happening in the other tire as well is very surprising. I suggest you visit the closest Decathlon store to have a quick check.
