Drawing its name from Portland, the Donnelly Tires PDX Tubeless Ready Cyclocross Tire delivers confident, reliable handling and performance in all conditions but especially the wet. Featuring a race-proven tread, the PDX uses a balanced center tread with aggressive shoulder knobs to balance fast rolling on the flats and confident cornering.

With cyclocross performance in mind, this PDX is offered with Donnelly's Tubeless Ready technology. Mounting easily to most tubeless-ready rims, the PDX can be run sans tubes for improved ride quality, increased flat protection, and superior traction.

Donnelly Tires were previously known as Clement tires, but due to a licensing have had to change their name. If you have used Clement tires in the past, Donnelly has retained the materials, designs, and compounds in these tires.


  • Cyclocross tire designed for racing in wet, muddy conditions.

  • Tubeless-ready design mounts easily to most tubeless ready rims.

Road Riders Beware
by britcpower

Off road this is a great fast rolling tire. Good Grip on mud and not bad on gravel. Run at 60 psi these run very fast on the road and are very quiet. Still give a very nice ride at this pressure. Off road 40 psi seems to be a sweet spot. Buyers doing a lot of road miles beware. The side tread has very widely spaced small knobs. If you bank over on a road turn these knobs offer little grip and feel squirrely. I have had these tires wash out at even moderate speeds. I have very little confidence when cornering on the road on these things. The other issue is that they tramline really badly if you touch the white lines on the road. I dread to think what they are like in the wet.

If you ride mainly off road these would be great tires but if you want to do some spirited road riding I honestly couldn't recommend them.
