I stocked up on 7-8 of the older 25mm 4000s just in case though I'll prob move to tubeless soon. I ran into the Conti rep for this area. He said they had made the tire slightly thinner. I found that weird. Why mess with a good thing? The 4000s were stellar. Anyway, he said they had no sidewall issues or anything like that but it does appear that the 5000 is slightly more prone to punctures.
