Surly ExtraTerrestrial 26 x 2.5" 60tpi Tire

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly's ExtraTerrestrial tires were designed to let you ride without limits by simply following the only tenet we have for tire design; they're high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off road touring tire that shines on hard pack 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. The ET tire uses a distinctly directional tread pattern 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 ExtraTerrestrial tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. It's made to be durable and versatile and is at home on tour or on the trail. Comes in 26 x 2.5" in 60tpi.

Bead Seat Diameter: 559mm

Casing: 60tpi, tubeless-ready bead (928g)

Product: Surly ExtraTerrestrial 26 x 2.5" 60tpi Tire
Ownership: a few months
Tech Knowledge: somewhat high

Pros

These tires lasted me 2,065 miles from Calgary,CA to Boulder, CO this summer. I didn't get a single flat. The tread held up really well. I was riding on dirt roads most of the time and went up and down many steep passes. Some single track. Some pavement. These tires handeled it all.

Cons

So far none. They worked great with my rims and tubes. No complaints.

Other Thoughts

Great for off pavement/off road touring.

Product: Surly ExtraTerrestrial 26 x 2.5" 60tpi Tire
Ownership: a month
Tech Knowledge: high

Pros

I bought these to replace my previous favorite tire: Schwalbe Marathon Mondial Evo 26 x 2.15

Roll fast over pavement/tarmac/bitumen and hard-packed surfaces

Roll well through non-sticky mud and moderate soft sand and decomposed granite (like on a walking trail or some cycletracks)

Surly's phenomenal product design and naming; also, the sayings on the tire's casing

They're tubeless ready and mounted very easily on DT Swiss FR 570 (33mm outer width) rims.

Cons

Nothing so far

Other Thoughts

I have some writing and pictures about these tires and some other things I ordered from Modern Bike (Arkel Dry-Lite panniers and Salsa Wanderlust rack) here: http://www.alwaysthewronggear.com/blog
