Pirelli

I purchased a previous version of this tire with black sidewalls in 2021 and had an excellent experience with them (about 2000 miles and no flats) so I bought a set of tan sidewalls this summer to replace them. I tried to swap them out today and, even though the SRAM website lists them as a compatible tire for the Zipp Firecrest 303 tubeless rims I'm using, I found it absolutely impossible to mount these tan sidewall tires on these rims, I had to use a tire lever just to get the first bead mounted. The second bead was absolutely not going to go over the rim. I have been riding and racing for over 40 years and have never had such an extreme problem mounting a tire. I'm going to have to return them for a different make and model for my wheels.

Waited until I had around 1500mi to get a review in for these.

Tested these in a range of conditions/road/light gravel. Ran the 28mm and 30mm on Reserve 25mm internal so they blew up a little bigger.

Overall I am really pleased - This is an amazing tire that I feel strikes a perfect balance of everything. Super fast, but not the fastest out there. Very good longevity for the speed and road feel you get.

Decent puncture protection (I did get two flats that I sealed no problem with plug. Both were on absolute terrible road debris area so no fault of the tire for the flat.

These tires EXCEL in the wet. Very confidence inspiring and not sure what tire I have run that gave me so much grip in wet/warm conditions. (wet/very cold conditions yet to be tested and is something I avoid)

This is a race tire, so it definitely isn't going to be the absolute longest lasting and best puncture protection, but they punch way above their weight for longevity/puncture and how much speed you get from them. Excited to try these in the 32mm version for the fall/winter season.

So far these tires are great, though I haven't really pushed them yet. They ride really well on both gravel and paved roads, which was one of my requirements.

I did just get new gravel wheels which have an internal width of 25mm and when I remounted these 40mm tires on the new rims the measured tire width increased from 40mm to 44mm! Although I am not surprised, this is just barely able to fit between my chainstays. I mean I have about 1mm on each side. So just be aware of this an add a few mm to the stated width if you have wide rims.

I've been riding Conti's for a long time. Gatorskins, GP4000SII, GP5000 TL etc. When I saw an Italian made version of the PZero's, I had to try it and I haven't looked back. The only drawback is that it is slightly heavier (GP: 250g, PZero: 288) - other than that, it is far more durable and has better grip, even on wet surfaces. Rolling resistance is about 1W more efficient on the Conti's but I will take durability over such a small margin. I have ridden for 2 seasons on these tires and have had zero flats. (I ride about 5000 miles/yr)
