Did the same ride in 2019, on my personal Bianchi on Rubinos, and had no trouble avoiding lockups.
So you changed the bike AND tires (and had experience for your second run) and yet you're concluding it was ONLY the tires that caused you to lock up the wheels during the descent? That's not how robust testing works. Your story sounds like you might have simply under-estimated the braking power on the rental bike, and that is why you locked up the wheels. There is nothing to indicate that the tires are what caused the lockup.
