The Pirelli P Zero Race was an upgrade from the stock WTB Exposure tires for my Cannondale Synapse Ultegra SE road bike. I have about 100 miles in on the Pirelli's. Running stock i21 rims; and both the old and new tires are 30mm width. Pirelli is an obvious upgrade. I ride for fitness - 150 minutes per week on the bike. I'm not an athlete. I ride on midwestern roads - pebbles, cracks, pot holes and lots of smooth pavement. A lot of my riding is on or hugging the shoulder of the road. I don't spend much time in the middle of traffic lanes, and so I don't get much benefit from any street cleaning. I also don't ride in a velodrome and I don't go off-road. Manufacturer recommends that for my weight I run at 67 psi - and so this is where they are set.PROS:1) Much faster tire. My slowest days on the new tires are about the same speed as the fastest days on the old tire. I estimate 0.5 - 0.75 mph improvement on average2) Tire holds air very nicely. Tubeless setup can be quite finicky. It took about 50 miles for the tires to seat in the rims properly. I just need to top off air every few days.3) Easier to mount than the old tires, but not it's not like spreading butter.4) Tires conforms to pebbles so well that you hardly feel when ride over them. Very smooth.5) Takes corners shockingly well, though I haven't ridden on wet pavement yet. I feel very secure taking corners faster.6) No flats, no sidewall issues.CONS1) At manufacturers recommended tire pressure, vibration from rough roads are more noticeable than the old tire. Old tire ran at 60 psi instead of 67 psi, this is definitely the difference. At 60 psi, the Pirelli tire runs smoother, but it isn't the manufacturer recommendation.2) Tires aren't cheap. Question is, were they worth it? For me, they are definitely worth the price, but price was not my number one consideration - but still I wasn't willing to pay the extra money for the tan sidewall. Can't say whether you could get a similar experience for cheaper on another brand.Overall, I doubt you will be disappointed if you purchase this tire.

the best all round tubeless tire, no more continental gp5000, excellent, no flats NOTHING, very easy to setup in wheels with a foot pump, good balance at all, rolling resistance-weight-durability (4500 km rear wheel) if you can save more weight you can use the SL version in front wheel.full recomendable bro

This is my second attempt at using tubeless tires. The first was a disaster, because when I had punctures (glass) larger than could be sealed by the goop in the tire, it was quite literally impossible to remove the tire to put in a tube to continue/finish the ride. For a year, I switched to Pirelli Road tires (with tubes). they were fine , except for occasional punctures mostly from thorns and "wire whiskers." Then In a few weeks time, I had so many flat tires that probably would have sealed themselves with tubeless tires that I'm again trying tubeless. So far, they feel terrific, roll VERY well, seemingly with no road friction or drag! The **** rating is because they lose 25 lb overnight. My riding buddies say this is temporary. We'll see.

Great tires light and supple

Love these 30’s, measure true to size, installed easy, provide a great ride in terms of comfort. My second set of these tires.

I switched from 25 to 30s when I got these Pirelli tires. I have never been and still am not a believer in fat tires being as good or better than narrow tires for speed. I'm simply not getting the speed coasting downhill . The tires are obviously going to be a little heavier. Because you're running at a slightly reduced pressure, the ride itself and the feel of the road is softer. Depending upon where you ride that may be great, but I like the feel of the road. It's sort of like a load of the ground sports car versus a family sedan. From that lower pressure that these tires, at least the 30s, are meant to ride at, they are a little bouncy. I don't particularly like that. I gave it four stars because the tire itself seems to be very well made and I haven't had any punctures yet. One day I'll try these in a 25 or maybe a 28 and see what I think. If you're going for a comfortable tire in the 30 range however, these seem to be quite good. I'm having no traction issues so far.
