N'Tense X'Ploration.

When the route ahead is an unknown the Donnelly X’Plor USH is the tire of choice. This adventure tire features a combination of firm center ridge and diamond-shaped side knobs that provide amazingly low rolling resistance and great cornering control.

The X'Plor USH is perfect for dirt road exploration, long tours and urban assault. The USH is named for the airport code of Ushuaia on the island of Tierra del Fuego, Argentina. Ushuaia is the southernmost city in the world, and the ultimate destination for adventure bike touring.


  • Smooth rolling and firm center tread for low rolling resistance.
  • Diamond-shaped side knobs for excellent cornering traction.
  • Integrated puncture protection belt under the tread for added durability.
  • Tire type: Clincher.
  • 120 TPI casing.
  • Claimed weight: 430 grams.

I was given a set of clements by a friend and used them until they ran smooth. I replaced them with these and when I bought a new bike I replaced the stock tires with these the USH. I run them with tubes and have never had a flat. i have over 2000 miles on them. the center bead wore down a bit on the rear tire so I rotated to the front and it is still going. Now with 2k miles the back tire center tread is wearing down. I ride a combo of tarmac and gravel but mostly gravel. I highly recommend these.

Excellent durability and puncture resistance

One of my favorite tires. I use this for winter training and urban gravel which tends to be a mix of pavement and dirt with a lot of glass and other debris. Riding steep gravel roads with these can be a little tricky due to the center bead, but the roll really fast on pavement. These tires last a long time and are more puncture resistant than other tires I've ridden. I was using these when the brand was Clement and these continue to be my go to tire now that Donnelly makes them.
