Regarding 235 65 17...some people have rubbing, some don't. It seems to depend on the individual patriot and the tire model.
235 60 17 is a 28.1 inch diameter tire. It is very close to the stock overall diameter (28 inch). It should fit fine. Here are some tires that come in these size that are on the more aggressive side.
Goodyear Fortera TripleTred,
Sumitomo HTR Sport A/T,
Toyo OPEN COUNTRY A/T
