The Origin8 Wildfire GX 700x40 folding gravel tire is designed for gravel roads, access roads, and backcountry routes, using a closely spaced small-block tread to maintain rolling momentum while adding traction on loose surfaces.

Its technical details include the documented construction, fit, mounting, compatibility, and operating configuration, helping you compare the product with the component or accessory currently installed on your bicycle.

Key Features

• Small-Block Tread: Gravel-focused tread pattern adds grip while remaining efficient on hardpacked surfaces.
• Connected Lugs: Bridges between tread blocks improve rigidity and reinforce the tread structure.
• Magnitude I Protection: A high-density nylon layer provides added puncture reinforcement beneath the tread.
• Folding Bead: Foldable construction supports a lighter and more compact tire package.
• Gravel Casing: 60 TPI casing in the exact 700x40 size.

Benefits

• Helps maintain control over loose gravel without using an excessively tall tread pattern.
• Offers a stable footprint for mixed-surface routes and unpaved access roads.
• Adds tread reinforcement for rides where sharp gravel and road debris are common.

Best For

• Gravel grinding, hardpacked back roads, access roads, and mixed-surface adventures.
