All my road bicycle punctures (few per year) are from tube getting pinched against the rim of the wheel. Usually after hitting the pot hole or curb.

- tetris11 4y agopro-tip: never fasten the nut around the valve that holds it to the rim, unless you know with certainty that the road will always be smooth. Any larger than normal bump will rip the tire at joint. Just keep it loosely on, but not tight.
- charles_f 4y agoVery good one, and similarly if you get out while it's cold and store your bike in a hot place, don't tidy that screw. I've had it fail once precisely on these conditions
- Tempest1981 4y agoAre you referring to Presta valves? It's ok/recommended to discard the nut on the valve stem?
- tetris11 4y agoYes presta too. I wouldn't discard the nut, since it provides a good support when pumping the tire, but just don't fasten it on tightl - maybe leave a few centimeters.
- sgtnoodle 4y agoThis thread reminds me of biking in to work with a friend. He managed to pop both his tires on the same wedge shaped rock.
- scott_siskind 4y agoYou need more tire pressure then. Either that, or you're using tires with some heavy-duty puncture protection.
- mickdeek86 4y agoDo you not partially inflate the tube prior to tucking the tire bead under the rim? This prevents the pinch in the first place.
