The Surly ExtraTerrestrial Adventure Tire is designed to ride without limits, featuring a high-volume, heavy-duty construction. This tire shines on hard packed surfaces, featuring a distinctly directional tread pattern that yields more traction than you might expect, yet still offers very low rolling resistance. With its 2.5" width, the ExtraTerrestrial offers enough width and traction for the soft stuff, as well.

The Surly ExtraTerrestrial Adventure Tire measures 26x2.5". 60 TPI casing. Tubeless ready.

Superior performance all around tire.

This tire is the best of both worlds, excellent off road traction and wide enough to get me through the softer stuff. On hard pack to asphalt the performance with low rolling resistance makes it fun to ride.

Cool big tires. Tubeless!!

These fit on an old 26" steel frame Nishiki mnt bike. The clearance was very tight but they do fit. They are Tubeless, works great!!! Fun tire; Awesome on dirt, they are large and loud on the pavement but smooth over the bumps.

Perfect for my AZUB

I am a 62 , 220 lbs rider. These are just right for stability and performance on my AZUB X both off road and pavement. I have been using them for 3 months now and am very happy with every feature.
