Adventure like never before.

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly ExtraTerrestrial 700c Adventure Tires were designed to let you ride without limits.

Outstanding design and incredible technology is created by simply following the only tenets we have for tire design &mdassh; they're high volume and they kick ass. Designed to serve as a heavy-duty off-road touring tire that shines on hardpack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats.

A distinctly directional tread pattern is and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between tread blocks.

The Surly ExtraTerrestrial 700c Adventure Tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. So what are you waiting for? Go the extra mile today with such high quality you're sure to enjoy the ride.

    I really wanted to love these tires
    by NorthCountryScott

    I ordered these tires to replace the Schwalbe tires that I also wanted to love. The tread design on the ET is pretty ideal for road touring and holds its own on gravel roads. It also doesn't pick up and toss pebbles at me. The size of the tires (700cx41) is ideal for loaded touring and does a great job of cushioning the expansion joints.

    Where the tires fall short is in protection from flats. They seem to love the thorns. I've had my tires for a little over 3 months now with no more than 1000 miles on them. 99% on pavement. I just repaired 2 more punctures. That makes 8 now. 8 flats is WAY too many on a $45 tire with so few miles on it. Zero flat protection. Primarily thorns. The aramid belt does nothing that I can see. The rubber compound is way too soft. The rear tire is showing significant wear. These won't last much more than 3000 miles with rotation.

    I have a set of Bontrager H2 hard case tires that have over 6000 miles on them - 1 flat.

    I really wanted to love these ET tires, but I cannot count on them for long distance loaded touring, so they will be relegated to short trips near town.
