What Makes the Ralson 26 x 3.00-3.45 Schrader Tube the Right Fat Bike Replacement Tube?

The Ralson Butyl Inner Tube in 26 x 3.00-3.45 is a fat-tire butyl inner tube built by Ralson Tyres, an ISO 9001 certified manufacturer, designed for the 26 inch fat-tire wheel size on a wide range of trail fat bikes, e-fat-bikes, and cargo e-bikes with chunky tires. The 48mm Schrader valve is the long-stem version, which makes inflation through deep rims and snow guards easier and pumps up with any standard floor pump or gas station air pump. Long valve, butyl construction, and good air retention are the practical features that matter when you are running fat-tire pressure.

Ralson is the tube brand that Tannus ships as the recommended companion for the 26 x 4.0-4.8 Tannus Armour fat bike insert. If you are installing Armour on a 26 inch fat bike, this is the correctly sized tube to use with the insert. The 3.00-3.45 size range fits inside a 4.0-4.8 tire when the Armour insert is also taking up volume, which is the geometry that makes the system work without pinching the tube. UPC: 193751006466. Schrader valve, butyl, Made in India.

FAQ

Why is this listed as a Ralson tube and not a Tannus tube?

Because Ralson is the brand that actually makes the tube. Tannus ships this Ralson tube as the recommended pairing for their 26 x 4.0-4.8 fat bike Armour insert, but the product itself is made by Ralson. Listing the actual brand keeps things clear for service, warranty, and customer expectations.

Why is a 3.00-3.45 tube the right size for a 4.0-4.8 fat tire?

Because the Tannus Armour insert occupies volume inside the tire. The tube is sized down from a standard 4.0-4.8 fat tube to leave room for the insert. A standard-size 4.0-4.8 fat tube installed with the Armour insert will pinch and fail. This 3.00-3.45 size is the correct geometry for the system.

Can I use this tube without a Tannus Armour insert?

Yes, in a 26 inch fat bike tire that is between 3.00 and 3.45 wide. If your tire is wider than 3.45 and you are not running Armour, this tube will be undersized and overstretched, which shortens its life. For non-Armour 4.0-4.8 fat tires, use a standard 26 x 4.0-4.8 fat tube instead.

Why is the 48mm valve length useful?

Longer valve stems are easier to inflate through deep fat-bike rims, snow guards, or fender setups where a standard short Schrader valve would sit too close to the rim for the pump head to seat cleanly. The 48mm stem clears most fat-bike rim profiles.

Best For

Fat bike and e-fat-bike riders installing Tannus Armour on 26 x 4.0-4.8 wheels, and any rider running a 26 inch fat tire between 3.00 and 3.45 wide who needs a quality butyl replacement tube with a long Schrader valve.
