Check out Western Bike Works for 27" tires. Amazon third party sellers can be such a rip-off sometimes. The Kenda tires are $20 at Western vs $36 on Amazon.

Funny reading the reviews for different tires, and people complaining about how the tire blew off the rim having only pumped it to 85 PSI. I found this out the hard way years ago. Many older 27" wheels have hookless rims, IE nothing to hold the bead of the tire to the rim other than the pressure itself. The tire may be rated 85, or even 95, but don't go near that pressure if you have hookless rims. I would say 75 max depending on the rim.
