Description

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.


Features:

  • Cyclocross tire designed for racing in wet, muddy conditions.
  • Fast-rolling center tread balanced by aggressive shoulder knobs.
  • Soft rubber compound provides extra grip and shock absorption.
  • Tubeless-ready design mounts easily to most tubeless ready rims.
  • Can be used with or without tubes.
  • Width: 33mm.
  • Weight: 426g.

Kicks [Gr]ass! And Mud... and Sand...

These are a durable, excellent all-around cross-tire that performs superbly on grass - I had been struggling around with a file-tread tire until these arrived, but once I put them on, they have been fast, light, and stable.

I don't have much experience racing CX, but I feel confident learning and practicing using these tires and wouldn't hesitate to jump into the nearest training race with them. They seem to be OK for gravel rides in a pinch, but I wouldn't put them to the limit due to the narrow size and higher pressures towards which they lean.

Pretty good

Tread is good. But, man, the sidewalls are really stiff. So the tire doesn't have that really nice feel to it like some of the Challenge or Schwalbe tires I've used. But, the tread is really nice in the mud and not bad at all on the hard packed stuff, too

Impossible to setup tubeless

These things are so difficult to set up tubeless, it keeps happening and it's driven me to leave a negative review. Every one of these I've bought I feel like I'm going to injure myself just getting them onto the rim, and then they don't seat half the time because they're so tightlywound, which is nothing short of ironic. I'm just going to switch to Challenge tires for good.

Great in the mud but still rolls fast

I love Donnelly tires and the MXP has always been my go to for CX season. However, I got some PDX tires for those few muddy races that end up popping up every year and was surprised at how fast they roll. They are pretty outstanding and I can't wait to rip them in a race this season.

Mud Rippers

Given the weather in the Pacific Northwest, these are my go to tires. I've raced and ridden the Donnelly PDX's in a variety of conditions, from dry to down right mud-fest. The tires grip when needed on those crazy off-cambers, and roll fast when speed is required. Easy to set-up and no issues running pressures as low as 25 psi.

classic tread, heavier new construction

Here are a bunch of details that might help weigh some trade-offs. First, the PDX tread pattern is fantastic. You can run these in dry conditions, or mud, or in-between. A file tread would roll slightly faster dry, but these are nearly as fast. A full mud tire would hook up marginally better in full slop, but these hold their own (and don't pack up as there is lots of space between the treads, which is key). On a course with some mud, some pavement, some gravel, etc, the PDX can't be beat. Now the variations. I loved my old, non-tubeless, foldable, 120 tpi PDX's. They were super supple and 270g (add 90g for a latex tube) but of course couldn't go too soft w/o worrying about pinch flats. Then earlier this fall I briefly had a Clement-branded PDX tubeless version (probably mfg'd roughly a year ago but sold in 2018) which weighed in at 430 g (not including the Stan's sealant I used) and had a much thicker, less supple casing than the non-tubeless version. First hard use (a CX race at low pressure), I somehow damaged the casing (never done that before - I'm 150lbs). It had no visible cuts or tears, but it had developed a significant bulge at one location (yes it was seated evenly). Finally I got the currently-selling Donnelly-branded PDX tubeless version. It's 495g on my scale. Yikes. The casing is even thicker, quite a bit more slipperyplastickyrubbery, and less supple than the older stock Clement PDX tubeless. The ride quality is comparable to the older tubeless version and not as good as the much-suppler, lighter, grippier non-tubeless 120tpi version. Both the Clement and Donnelly-branded tubeless specimens mounted tubeless w/o an air compressor on Ritchey WCS Zeta Disc rims, however both allowed some air to escape for a number of days despite sloshing a fair amount of sealant around in there, as evidenced by air bubbles coming thru the casing when viewed underwater. That's my experience. Hopefully they'll make a race-worthy tubeless PDX soon.

Ease of use.

Mounted these tires with a floor pump, no problem. Went on my rims with ease. My go to tires for PNW mud.
