Old crusty skin walls are fragile and dangerous but sure do have a nice ride. I’m picking up a pair of Paselas today for my 1983 Schwinn Voyageur, black sidewalls. I rode the bike on some other tires for a few months, wore them out, and threw the skinwalls
on for fun a few weeks ago to see how long they’d last, but I haven’t been commuting on them, been using my other bike. I was excited to learn my preferred LBS recently started stocking Paselas in 27 x 1 1-8 and 1 1-4 for $25/pc, competitive with online prices after shipping.
