2001 SUNNYBROOK 27RKS 5TH WHEEL QUESTION

I think your rim has coding that tells you specs. Not sure, but any wheel shop would know. I have a 2001 30RKS and 16" wheels with E rated tires were an optional upgrade. I took it and am glad for the extra safety margin. Got some nice looking aluminum wheels.

I know my 16" Ford truck wheels do not fit. Found out during a roadside emergency when my RV spare had dropped off and I then lost a tire on the way to get a new spare. Not a happy day.
