A year or so ago, I picked up a Michelin Pilot City tire (700x32C) to see how they compare with the twice-as-expensive Schwalbe Marathons we’ve been using on the Tour Easy recumbents.
Having replaced a worn-out Marathon last summer, this was unexpected:
I’d blame that failure on overpressure, but I’ve been running the back tires around 70 psi, well inside their 87 psi (that’s a nice, round 6 bar) sidewall rating.
Being able to swap a back tire in the Basement Laboratory Repair Facility made up for a lot…
