After riding 28 mm tires for most of the last two decades, I am moving more towards 32 mm tires. I blame the Clunker Challenge for that - when I first participated in 2016, it was a revelation to me just how well 27 x 1 1/4 tires at 70 psi handled not just bumpy local roads, but dirt roads as well. The 700x 32 Paselas on one of my 2021 Clunker entries on a battered Cannondale ST400 shocked me as how smooth they were. The biggest surprise was how well the 27 x 1 1/4 tires on my '76 Puch felt, and how shockingly smoothly they ran.
