I went back and forth on this issue when I had my 14 rally's. I suppose it's not really relevant to this thread...but I require a bit more out of my street tires than others might. With me it's more of a safety factor and not as much an originality thing. I decided to give up my 14s while I could still get a good price for them(they were practically new) and opted for some 17s with the best tire I could get for the money I was willing to spend.I loved the Firestone Wide Oval Indy 500 tires I had on my rally's but realize4d that the days of a decent 14" or 15" tire are gone. BFG TAs are rock hard compound these days(the G-force sports are pretty good tires) and you are taking your life in your hands running them,IMO. Same with Cooper or Dunlop GT.
Not that anybody cares, just my $.02.
