Surly Black/Grey 700x41 ExtraTerrestrial 700c TLR

Tubeless ready version of the ExtraTerrestrial tyre

When you’re out on a ride the last thing you want is to be limited by your tyres in any way.

Our ExtraTerrestrial Tyres were designed to let you ride without limits by simply following the only tenets we have for tyre design: they’re high volume and they kick ass.

The ExtraTerrestrial tyre was meant to serve as a heavy-duty off-road touring tyre 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 Aramid cap under the tread to protect against flats.

The ET Tyre uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tyre with such little rolling resistance. The tread is low profile with a file tread in between tread blocks. The ExtraTerrestrial tyre has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces.
