S7 rim/tires sizing

[oskisan]

This has been discussed so many times that I am rather embarrassed even asking this question. I knew that 26" S7 rims would not take a regular 26" tire, but I never ran into a situation with a 20" S-7 rim until now. Does the same apply (I am almost certain it does)?

Up until now I have always had an abundance of 20" schwinn stuff, but have sold off a lot of things and am now trying to fit a 20" new tire onto it..

Thanks,
Ken
