tyres, tubes, wheels - vintage sizes

Hi everyone, this is probably a silly question, but anyway: I have a vintage road/racing bike with 27"x1" tyres. These need to be renewed now but it's impossible to find that size, so it'd probably be easiest to just switch to 27"x1 1/4 which is the standard size now. I'm just wondering if I will need new wheels as well then since the tyres might be too big for the wheels? Is that a problem?

Would you recommend getting new wheels too?
