I don't know how strong they need to be, but my impression is that Grant prefers tires with stronger sidewalls--presumably because they are safer?
I am a fan of high performance tires for event rides. The Pari-moto tires are fantastic. I also have Grand Bois Cypres for my 700c bike. For "everyday" riding, I don't need high performance. More resistance and weight is fine, but more comfort is always welcomed. If I can get more sidewall cut resistance/flat resistance and high performance, then that would be great. What tires are a good compromise? Not necessarily the highest performance, but a good balance of these other traits? How much of a difference do the kevlar/aramid/other strips make in terms of flat resistance? Grant asks (something like), "Why can't I run a tire with stiffer sidewalls at lower pressure and still get good performance?" --In terms of performance, anytime you flex the thicker casing, there will be an energy loss (you need to take the kinetic energy of bike motion and convert it to mechanical energy to flex the casing) and therefore (it stands to reason) it should result in a speed/performance loss. However, in terms of ride comfort, I think Grant has a good point. At lower pressures, the casing will flex and absorb the shock from the road, and the ride should be just as comfortable. I would find it hard pressed to believe that a 25 mm tire will be as comfortable as a 35 or 38mm tire at lower pressures (and stiffer sidewalls). (In terms of performance there is no doubt...)
