If you want the same size wheels, you can find 27" wheels easily. Note that the diameter of the wheel has nothing to do with the marked size--it's dumb, I know.

Or, if you want a larger selection of tires, you might be able to use 700c wheels, which are slightly smaller in diameter. If you have enough room to adjust the brake pads down 4mm+, you can most likely use 700c.
