Depends on where and how much you ride -- roads are cleaner some places than others. I encounter rock chips in areas where it's scattered for traction and glass is a problem in certain areas. From your commute mileage, I'm guessing you must be near the core? If so, it's pretty clean there.

I get a few flats a year, but it's no big deal. Overall, roads are good.

I just fixed a flat on my wife's bike, yesterday. OEM tires on her Jamis Aurora. It was a shard of glass and she was biking solely in NE (Portland) for the last week. I ride 4-6k miles a year and, on a set of typical tires I only get a flat every couple of months. However, that is still too often. It means I'm late to work or to an appointment or even to meet a friend. We are dedicated carless so a flat is usually more than a minor inconvenience. I was having flats at about the same rate on my Brompton until I switch to a set of Marathon+ and I'd estimate there is at least 4k miles on those with no flats. Whatever downsides came with the Marathons are/were not noticeable to me,other than the feeling of trying to bend rebar when mounting them on 16" wheels. I thought my backup hybrid (my primary until a month ago) had M+ on them but I looked and they are Continental Contact Plus. I had forgotten the shop I went to didn't have the M+ but they said they would install the toughest set they had in stock. I'd guess those have seen at least 3K with no flats.

I'm not arguing here. Maybe that is coincidence or dumb luck. However, maybe "overkill" is working.

OMG, thank you. I didn't know that existed.

I had three flats on my marathon + in am month when it was always wet. a sharp nail on the road a blind metal piece in Home Depot parking lot. the a tiny wire on the road. so portland is not always safe. but I put in 20+ miles a day on my bike anti is a e bike so it weights more and goes faster.

I had these for mixed road/crushed limestone/gravel commute. These have been bombproof for my commute. Never flatted and they wear well and are good on pavement as well as the middle section is flat like a slick. May not be the best choice if you are strictly pavement, though they work on pavement well (note Donnelly tire used to be Clement tire).

Here is the trick to mounting a difficult tire. When you get to moving the last, hard section of bead over the rim, make sure the bead of the rest of the tire is in the *deepest* middle section of the wheel. Just go around with your free hand and pinch it towards the middle. This loosens the remaining bead and it will usually easily slip over the rim once you do this. I had some tires that were a bear to get on until I came across this trick. It is obvious - once you think about it

I've been using pirelli cinturato velos in 32mm for winter commuting. Excellent puncture protection, they roll well, easy to mount, and tubeless ready if you want to go down that route.

I can never tell when people are joking, so forgive me. You know it doesn't work that way, right?

I was sorta joking, but maybe a little superstitious?

The tire that gives me the least flats is the continental ride tour. In 32mm its not large. They are cheap 20 or 25 bucks. They also suck for feel compared to a pasela but you likely wont get a flat.

Impervious to nails, pinch flats, drywall screws, beer bottle bottoms. Weight gain offset by ditching the pump, C02, tire levers, patches, spare tubes.

I haven't pulled the trigger yet, but one more flat on my commuter and I'm doing it.

I know I'm a little late to the game here but I've had great luck with Vittoria Randonneur 700x32. They pump up closer to 29 or 30 and top out at 85psi. My GF and I use them on 3 different daily-used bikes including a skid-happy fixed gear and the only flat we've gotten in 3 years was when a creep knifed my GF's tires after she rebuffed his advances.
