Inflated to 70psi (max 85psi) the max width was 35mm with an aspect (height of ~30mm. As a reference a mounted Pasela 37-622 measured 36mm.
It will likely be easier to sell these older bikes with wider tires. Only $24.99CAD (after inflation, pun intended!) A mid seventies Peugeot tourer will get them for sure.
Meaty looking tire.
That's a great choice, possibly the widest 27" tire available(?).
Tread looks like a copy of the 700x41c "Nimbus" hybrid tires that came stock on my 1991 Specialized Crossroads.
Should help to give an older bike an updated look, while making any 27"-wheel bike more versatile!
I would probably run those tires at a modest 55psi for my 140# rider weight.
Now to see what those tires cost state-side...
EDITED: Ughhhh, don't seem to be imported to the US at this time.
