Seeing Portland is known for perpetual deluges and rainy weather, the appropriately named PDX Tubeless Tire by Donnelly ensures reassurance and grip when you're racing across mud-caked courses and rain-soaked grass fields. Although it's great at racing across muddy, rain-soaked courses, it still performs admirably in a wide variety of conditions, thanks to its center knobs aligned for fast-rolling speed on packed dirt and pavement. The fast-rolling center is complemented with leading edge knobs for grip as you lean into corners, so you don't wash out without warning.
This particular version of the PDX Tire is setup for either running tubes or going tubeless, setting up quite easily in tubeless form for those desiring a bit more grip at lower pressures, as well as self-sealing reassurance. Additionally, it has an Aramid-reinforced bead that protects it from race-stopping punctures, slits, and cuts.
Please note, Donnelly Tires were formerly known as Clement, but have changed their name due to a licensing agreement. If you've been running Clement Tires on your bike for years, rest assured that Donnelly has retained the exact design, rubber compounds, and tread patterns for those tires of the same name.

Worst tires I have ever bought
I ordered these based on the good reviews and similarity to the tread pattern on my sons old tires (smaller wheel size/bike). I had extreme difficulty getting one tire seated. Once seated properly, I put the wheel on the bike and the tire has an extreme amount of wobble / run out. It is enough that it will be noticeable while riding. I cannot get the second tire even seated. I tried on both front and rear wheels and it just will not seat. At this point, I will contact Donnelly directly for next steps. I already discarded the packaging and with one tire set up with sealant, I don’t think it could be returned.

- I've put it through the wringer
I use this as the only tire for gravel, CX racing, and just rolling local MTB trails. It is grippy when it needs to be and flows when you hope it would.

- I've used it once or twice and have initial impressions
Sets up tubeless super easy. Great in the mud while still rolling quickly.
