Thanks. Underinflation may have been a factor. I rode the bike a few times before getting a pump, around 1-5 miles per trip at very modest speed on pavement. I think the pressure was around 40-50 psi when I got the pump. The Specialized Hemispheres recommendation is 75-100 psi. Now I usually keep it around 80.

Does your bike have clearance for 46 mm tires?
Seems to, but I'm just eyeballing the brakes and frame. It's a stock Specialized Globe Carmel from 2009. Brakes look like Promax low end linear pull brakes (in ye olden days I would have call these side pull), with enough adjustment to clear slightly wider tires. Frame looks wide enough.
