Dave, and Paul, nobody has 185/65R15 in Sportrac5. Nobody. That's the size we need on the front of Spyders. Vredestein has to make some. And if anyone actually does have them, I don't want them. I want new, fresh rubber, not stuff that's years old. Freshness matters.
195 is too wide for a 4.5" rim, actually 185 is a tiny bit too wide, the widest tire that fits properly on a 4.5" rim is a 175. But I've had no trouble with 185/65 for 15 years and 40,000 miles.
Dave, you don't want 60, 55, or 50 series in the front, they're too short.
But 195/60 in the back is fine, I ran that on my old Spyder for ten years. I have 205/60 now, and I really can't tell much difference.
