Michelin I believe makes the widest 27" tires, the 1-1/4" World Tour and ProTek are a bit larger than even the 1-1/4" Pasela.
The 27x1-1/4" Zaffiro isn't quite as wide as the 1-1/4" Pasela.
Old, aged tires can measure considerably wider than new tires, and some models are affected much more than others from years of inflation.
How wide is the Swifttire 27 x 1 ⅜" tire? That should be a fairly direct comparison to the Pasela 27 x 1 ¼" tire, 32 mm for the narrower one 35 mm for the wider one. The cross-section is 19% bigger in theory, if the casing thicknesses are the same. If that is borne out in the real tires, comparing on the same rims, there should be significant difference in cush between these two sizes.
