So, this is an interesting topic, internal width. My GoZones are 24mm IW 30mm EW. Last week during a training ride, I got a partial flat or lost pressure in my front tire at the last 2 mi. I was able to make it to my car without a complete flat. Pressure was low, no signs of punctures or damage. I do remember hitting some debris, which I expected to find the damage afterwards.
Got home, tire completely deflated. Swapped to a new latex tube. Inspected the old tube. No holes or slashs. Pumped it up to about 25-30psi and left it in the garage over night. No loss of pressure. I’m wonder if running 28s on a 24IW wheel caused a “tire burp” and loss of pressure?!
