With good resistance to heat and harsh weather. It has better air tightness and durability, which extends tire life due to restricted air loss 【Pick the Right Tube Size】Check the sidewall markings on your tire. Select the tube that has the same diameter as your tire. Tire width should fall into the range of tube width 【Installation Tips】Inflate a little air before installment, to avoid crack or damage during installment; Install the valve correctly, which must be 90° with steel, and the nut must be well locked; After installment, please check the tube is in the right position between steel and tire, make sure the tubes are not clamped by them. Inflate the air according to the pressure standard of the tire Remember to always add a little air (to give the tube form) to the new inner tube before installing. This will prevent it from bunching up and/or causing a pinch flat or possibly blowing the tire off the rim (when you immediately and fully inflate) which ultimately will pop the tube. Please kindly confirm the size of your bike tire before you buy, width between 35mm-43mm tires. Before inserting the new tube, make sure to check for sharp/pointed objects inside or embedded in the tire, that could puncture the tube. Remember to always add 20%-30% air (to give the tube form) to the new inner tube before installing it. This will prevent it from bunching up and/or causing a pinch flat or possibly blowing the tire off the rim (when you immediately and fully inflate) which ultimately will pop the tube. Check tire air pressure regularly; Try to keep your tire properly inflated as much as possible. Never overinflate and of course, don’t underinflate. Place the valve through the hole in the rim. The valve should stick out at a 90-degree angle. Screw the valve cap on tightly and securely. After installation, make sure the tube is fully inside the tire and not pinched between the tire and the metal frame. Now you can inflate the tire to recommended pressure levels.
