I have a vintage schwinn traveler with 27 1 1/4 tires. I cant see what the actual rims say.

They are pretty out of true and someone on CL posted a 27 1 1/8 wheelset with 27 1 1/4 tires. I dont know the original specs so well but please let me know if it could work as an even switch out. Or is it so mich of a difference?
