When to Replace

  • When the valve stem is damaged, corroded, or leaking
  • During every tire change as a preventative maintenance measure

Installation Tips

  • Before installing, inspect the interior of the tire and rim for debris or sharp points.
  • Ensure the rim strip is correctly positioned and in good condition to protect the tube from spoke ends.
  • Slightly inflate the new tube to give it shape, which helps prevent pinching during mounting.
  • Use a suitable bead lubricant on the tire for easier installation.
  • Confirm the valve stem is straight before inflating to the pressure specified by the tire manufacturer.

FAQ

This tube is designed for 19-inch motorcycle or dirt bike tires in the listed size range: 2.75-19, 3.00-19, 70/100-19, and 80/100-19. Matching the tire width and rim diameter is the key check before ordering.
It is intended for bikes using a 19-inch tire in the supported size range and is listed as compatible with Surron, Talaria, and Segway models that use 2.75-19, 3.00-19, 70/100-19, or 80/100-19 tires. Always confirm the tire sidewall size and make sure your rim is a 19-inch wheel before installation.
This tube uses a TR4 straight valve stem. A straight TR4 stem is commonly used on motorcycle and off-road tube setups, but you should verify that your rim's valve hole and clearance match a straight stem configuration before installing.
Common signs include repeated air loss, a puncture that cannot be reliably patched, cracking or age-related rubber deterioration, pinch-flat damage, or a valve stem that is leaking or separating from the tube. If the old tube has been run flat or has multiple repairs, replacement is usually the better choice.
Installation is usually moderate difficulty if you have changed motorcycle tubes before. Typical tools include tire spoons or tire irons, a valve stem tool, an air source, and rim protectors if you want to reduce the chance of wheel damage. Lightly inflating the tube before fitting can help prevent pinching. For most riders, tube replacement takes about 20 to 45 minutes per wheel depending on experience and whether the tire bead is stubborn.
The most common causes are punctures, pinch flats from impacts, running incorrect tire pressure, old rubber aging out, spoke or rim strip issues, and valve stem stress from tire slip on the rim. If you are replacing the tube, it is smart to also inspect the tire carcass, rim strip, spoke ends, and inside of the tire for thorns, nails, or sharp debris before installing the new one.
A heavy-duty butyl tube is generally chosen for better puncture resistance and slower air loss than thinner standard tubes. The tradeoff is that heavier tubes can be a little less flexible during installation, so using proper tire tools and avoiding pinches during mounting is especially important.
