Surly ExtraTerrestrial Tire
Best heavy duty touring tire for mixed surface adventure seekers.
This is the ultimate workhorse for riders who prioritize reliability over pure speed. It sacrifices a bit of rolling efficiency for a bulletproof casing that laughs at sharp gravel and debris. If you’re planning a long-haul tour where a flat tire is the last thing you want to deal with, this is your rubber.
