Is this size tire more prone to flats?

Not inherently. Larger riders, or those dealing with rough pavement, will report more pinch flats with smaller tires. Properly inflated and on equal surfaces with the same rider, I personally do not believe that any particular tire size is inherently more flat-prone.

That being said I don't ride 20s... in fact I put 25s (!) on the bike right before Ride the Rockies and I'm not sure if I'll ever go back...

Thanks. I swithced out tires before an 80 miler on Sunday. My old set was thread bare, but after I tossed them I realized I had 20s instead of 23s. They seemed to do OK, but I was waiting for an explosion. Think I'll switch them before the next century.

A few years ago I used 20's, thinking they were more aero and lighter. I got tons of pinch flats. I since went to 23's and have never had a pinch flat, unless you count the time I ran over a 2x4 at 45 mph and blew out the tire and dented the rim.

On my fixed gear bike and vintage steel bike, I used 25's and 28's. It truly does make a better ride, and if you are not racing, any minor performance loss due to extra weight or whatever is irrelevant.

Now I don't even use 20's on my narrow, aero, carbon tubular rims.

"A few years ago I used 20's, thinking they were more aero and lighter."

They are lighter and are more aero. Jeez

Ok, I should have said, "...thinking that because they are more aero and lighter, they were better."
