My old narrow tires would tend to collect cuts in the tread, sidewall cuts, and other damage. After a thousand miles or so, I’d tend to be able to see the cords in some of the cuts, and I’d occasionally dig bits of glass or stone out of the rubber. I just don’t see the same sort of damage after 3500 miles on a pair of 650x42 tires. I’m not generally riding over needles or goat heads, and I avoid broken glass as much as possible.
