Have about 500 miles on my set, rear is showing a slight flat down the middle and the front just had the ridge wore off. I have these set up tubeless with 65 psi front and 67 rear, wheels have a 25mm internal and tires balloon to measure 31.5 mm.
These aren't going to last thousands of miles; they are race tires that wear quicker, I will live with that cost because these definitely make you faster, combined with the right wheel, and grip as good or better than all the other tires I have tried.

I've tried these, maxxis, specialized, challenge, and panaracer. The pirelli rubber is hands down the best rubber you can get. It hooks up in the wet, it is happy in the dry, it doesn't care about the cold and will hook up (the best of everything I've tried) in the snow. The semi slick middle does roll really quickly, it's not as fast as a challenge or schwalbe but it's within 5% in the real world. The shoulder knobs are amazing and do help paddle through mud. The only "bad" thing of these tires is that they have a thick sidewall. You'll never puncture but they don't feel like riding on silk. Also the lifetime of these tires is ridiculous, I ran one set until the rear tire went bald, it took two years and about 1500 miles riding year round in New England. I love these things.
Pirelli, please make a racey version with thin sidewalls and change NOTHING else.

I bought new Chris King hubs (in 2019) and complete wheel set for my older 2006 Fuji carbon road bike.
My big problem has been removing or installing any new tire'..it's extremely difficult, mechanics also have helped me and had much difficulty.
I had a very hard time installing the gator skin tire on these 2019 tubeless compatible rim(s).
If I had a flat with these tubed gator skins, I likely could not replace the tube out on the road due to inability of removing/installing tire.
Most of my riding is within 20 miles of my home'
This deserves a phone conversation.

I bought the 40c race variant. Weight: 486/492 grams (475g spec). Grr...hate when tires are heavier than spec. Almost returned them, but didn't. No issues with mounting, using TPU tubes. First ride was 61 miles, 4.1k gain, 35% gravel. PSI per silca app, at the high end.
Sweet mother--these are indeed fast tires. Impressive on tarmac. So, I'm expecting them to be mediocre on gravel...but no, they grip very well. Almost shocking so. Climbing, descending, loose turns--all very good. Supple ride as well, better then sbc s-works pathfinder.
Damn The French. Never can be relied upon (I am French heritage so I know). In the end, these will be my go-to tires. Mon Dieu!
