| Jun 29, 2020 at 6:17 | comment | added | Acccumulation | My understanding is that "section height" is the standard term for what you are referring to as "diameter". The diameter of a tire is the distance across the entire tire, not the distance from the outside to the inside. tirerack.com/tires/tiretech/techpage.jsp?techid=7 | |
| Jun 29, 2020 at 1:56 | comment | added | Armand | This answer seems not to consider that tires are made of layers of different materials (not just "rubber"), are not uniform in thickness or composition around their outside, have varying tread patterns and depths, and varying contact patches with the road. No evidence is given that one feature difference between the two named tires is responsible for both the rolling resistance and flat resistance performance of those tires. | |

That definitely saved me much more time than the bit of rolling resistance cost, and certainly the constant, predictable cost of longer travel time is less of a problem than the time of fixing a tyre when you just happen to be in a hurry. (Not to speak of the time wasted when the puncture happens just when you don't have a pump and spare tube at hand...) | |
| Jun 29, 2020 at 0:49 | comment | added | leftaroundabout | I twice switched between whether to up- or downvote this question. It makes a couple of valid point, but the implied conclusion is questionable at best. “Puncture protected” tyres can be quite worthwhile for a bike that's mainly used in the city: rolling resistance is not really important there, and (depending on the city) there's a lot of glass lying around against which the kevlar band does offer some protection. | |

| Jun 28, 2020 at 22:29 | comment | added | Džuris | 5-10 minutes to repair? I probably wouldn't even find the puncture in that amount of time. | |

| Jun 28, 2020 at 12:29 | comment | added | juhist | @Klaster_1 Tubeless tires mainly prevent snakebite pinch flats. A snakebite pinch flat is often a three-fold user error. Firstly, the user selected a stupid 23mm wide tire whereas a 28mm wide tire would be better. Secondly, the user forgot to inflate the tire often as bicycle tires leak air naturally very quickly -- far quicker than car tires do. Thirdly, the user rode to a hard bump on the road or a kerbstone at too high speed. With often-inflated 28mm tires, as heavy and large inner tube that fits to those tires, and careful riding technique, I have not had any snakebites recently. | |
