Simon: 6/7"x15 will work fine, but yes tires are getting harder to find in other than 195, 205, 225 in most cases, without going to a somewhat "race" track tire. Check out the Toyo RA1 205-225 and will fit within the rims sizes you are looking at. And my guess it will improve the handling of your car, but not the ride. Looks like a nice car, enjoy it: Hope the input helps
