the major functional difference between 700c and 27" is how hard it is to find tires. Since you now have two new tires, your 27 inchers are every bit as good as 700c for your 4k ride.
have fun.
Yeah, you're right. I rode straight-sided 27" rims in the 60s and 70s and wasn't aware that some manufacturers had later made 27" hooked rims. The OP's Matrix ISO Tech tires look like they had a bead designed for hooked rims. One should only run wire bead tires on non-hooked rims. I see that the 27" Gators only come in wire bead, so all good anyway. PITA to tour with wire bead, though, because of the spare problem.
