I'm finding that, with higher pressures (110) the tire (almost) skates over the bumps in the chipseal. Higher than that might be better, but the top rating of the tire is 110. I'm not seeing a lot of difference at 90. But it's a 22mm tire. The 25mm at 90 feels squishy, and I have never enjoyed that sensation. On a side note, I forgot to check the front tire of my town bike, yesterday, and rode it at around 25 psi. A lovely ride. Another 25mm tire. Even my town bike is a road bike, with upright bars.
