Heavy-Duty Off-Road Touring MTB Tire
The Surly ExtraTerrestrial 650b 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 46mm" width, the ExtraTerrestrial offers enough width and traction for the soft stuff, as well.
The Surly ExtraTerrestrial Adventure Tire measures 26x46mm. 60 TPI casing. Tubeless ready.

I have over 200 miles on these already and they are surprisingly fast. I am running 40PSI and my average speed is up. I have been commuting to work 32 miles round trip this summer. These tires are smooth on the road. I went out on a gravel ride this weekend. Ran into some chunky gravel and these tires held their own. I would but these tires again.
