Really fast and smooth tires with decent puncture resistance for how thin they are. I have these in 30mm mounted on Reserve 42|49 wheels and the front tire measures 34mm at 66psi (33.5mm rear at 68psi), it also has a more bulbous shape than I'm used to for Pirelli tires. I doubt I'm any faster or slower due to this fact but it just looks huge and the comfort is almost to good as sometimes I miss feeling more feedback. I've had at least one small puncture that sealed almost instantly with Silca's new sealant, I didn't notice until after the ride when I saw a few dry spots on my seat tube. Grip is also superb as you would probably expect, I haven't had them on wet roads but I'm sure they would be excellent there as well. These have been great for long rides on imperfect roads, my longest ride has been 85 miles and I didn't feel nearly as beat up as I usually do.
My quest for the perfect larger road bike tire is officially over! After GP5000s S TR 32s and then Corsa Pro Control 34s I decided to try the 35mm P Zeroes. All I can say is "Wow!".
To start with they are by far the easiest tire to set up tubeless that I have ever found. They have a larger thicker bead than other tires, plus the bead is built in a way to make a strong seal against the rim bottom before it has hit the rim edges. One of the many brilliant design aspects of these babies.
The tires are a bit heavier, but I'll take that after having to deal with a zillion punctures on the Vittorias (all sealed, but the tires never held pressure well). Speaking of holding pressure, these guys also do that extremely well, some of the best tubeless tires I have had. They are only losing a couple psi per day. I'm also expecting good endurance out of them, they feel much more solid than the competition.
The tires have a profile that I love, with a pronounced curve at the crest unlike other tires which are flatter. This makes for both a great ride and for great cornering. I feel a notch more confidence in corners on these compared with the others. They are around 35.5 mm wide on my 25mm internal rims.
If you are looking for a wide performance road bike tire, you have found it!
The P Zero Race TLR has been my favorite tire for the last 5,000 miles or so. In that time I've had one single puncture. I ride in a city with tons of bad roads that include potholes, glass, rocks, light gravel, etc. but these have held up very well. I'll notice all spots on the rear tire where I obviously hit a sharp rock or something and now feel very confident that I don't need to worry. I started using these after getting way too many punctures with GP5000s and won't ever go back. They feel plenty fast to me personally.
I think the concept of the TPU bike tubes is a great idea, and I've tried another brand with mixed results. The performance and comfort was there, but the reliability was spotty. Some tubes would last the life of the tire, others would fail early with slow leaks. The Pirelli tubes have been much better: They resist kinking or twisting when mounting, feel more durable than brand "X" and so far have been trouble free. I like being able to run lower pressures than butyl, and the weight savings makes them almost equal to tubeless, but without the hassle and mess. Granted if you do have a blowout it's an expensive tube to throw away, but it's a great way to get near-tubeless performance without the goop.
