Hello riders!

So I will order up on the Internet some Panaracer Pasela for my old 27 inch Niji, I would like to go for narrower tires but I'm not sure it can fit.
I searched on the Internet but the answers are confusing, some say yes some say no so I'm not sure

If I order a 27x1 1/8 Panaracer Pasela, will it fit and keep a good and narrow shape with 27x1 1/4 inner tube and 27x1 1/4 wheel?
How about the 27x1 Panaracer pasela?

Thanks!
