Larger surface area surely increases the risk as there is more area that could run over glass shards.
I have 700x35, or 38, can’t remember. Had 1 flat on the front wheel in the entire lifespan of the outer tread. Second outer tyre now and nothing so far.
i’ve got 20 and 24 inchers and i live in goats head country. i cannot keep them inflated for the life of me. I am this close to just putting solid rubber blocks on my wheels
Marathon plus touring tyres is what I use and it isn’t far off solid rubber blocks. But with the amount of broken glass on my commute its probably worth it.
Meaning more surface area to hit something sharp. Yeah the larger area means lower pressure on the contact surface but I don’t think that’s the deciding factor in whether something punctures your tire. Best way to prevent punctures is tougher tires rather than larger ones. The lower pressure just helps with stuff like loose gravel or sand.
There are also puncture self repairing tires now. They have a gel like layer on the inside which gets pushed out into the hole sealing it. I have them and haven’t had a flat in over 5 years.

Because they should get fewer flats. Larger surface area and all that.

That mKes it more likely to get flats though.

That is what happens after the puncture, though. Doesn’t really change anything about what I said. But if that works for you, that’s good.
