Finally changed my first gp5000tl on rear as I was seeing threads. No visible flats in well over 2k miles including at least 20 on gravel. They are FAST. Using orange seal. As before, it was an epic battle to fit the new tire on Reynolds assault rim, but worth it. I may go back to my panaracer Evo A tubeless tires for winter as they have more sidewall protection, but slower - had something like 10k on multiple tires never flatting.
