Surly ExtraTerrestrial 29 x 2.5" 60tpi Plus Tire

A 29" version of Surly's high-volume, heavy-duty, off-road touring, set-it-and-forget-it ExtraTerrestrial tread. Like its 26" counterpart, it was designed to shine on hard pack surfaces and features an extremely low-profile, directional tread pattern that offers tons of traction with hardly any rolling resistance. With a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread, ET gives you more flat protection than you ever thought possible. Available in 29 x 2.5" in 60tpi.

StarStarStarStarStar Excellent all-around commuting/bikepacking tire

by
Product: Surly ExtraTerrestrial 29 x 2.5" 60tpi Plus Tire
Ownership: a month
Tech Knowledge: somewhat high

Pros

Fast-rolling
Great for multi-use riding

Cons

Heavy (on paper)

Other Thoughts

I just finished a 125-mile bikepacking trip on mixed terrain (asphalt & 2-track). These tires performed very well and rolled fast. There were a few sections of greasy mud & sand, and they got a little squirrelly, but I expected as much. I was also running fairly high pressure (around 40 psi). All-in-all, I'm extremely pleased with these tires on my Surly ECR. Well-done, Surly!

StarStarStarStarStar Wow!

by
Product: Surly ExtraTerrestrial 29 x 2.5" 60tpi Plus Tire
Ownership: several months
Tech Knowledge: high

Pros

Massive cross section/volume and Bomber tough with the best street/hard pack tread yet. They laugh at goats head thorns and 6' curbs seated (on my Giant AnthemX full sus, which has become my favorite street bike ever!!!) Great all around traction. I can roll with confidence amongst the 2 ton death machines on any urban "pavement". Blew some folks away on the "bobsled" run flow trail (@15 psi).
Seated on TLR rims with a hand pump, hold air for months.
Huge rolling diameter. Low rolling resistance (tubeless), carry momentum very well and can run very soft terrain at 12 psi! Hardpack snow trails are no problem. Like putting good SUV tires on. I keep up with the roadies (@30psi) and the commuters are jealous.

Cons

HEAVY!!! These are true Plus size tires. Absolutely No Other Issues!

Other Thoughts

I couldn't be happier with the Surly E.T.s performance in all conditions and wouldn't trade them for any other combo tire. I've run slicks, semi-slick, SB8s, Big Apples, you name it. Urban Assault specialists that are also my best bikepackers. I've ridden the Slickrock trail dozens of times and can't wait to get these beasts down there. Halve the weight and they would be killer observed trials tires.
55 years in the saddle and I'm still surprised!
