The pickins are slim.
I've been looking for a good choice in 205/60R15 for a long time. Check my 215/60R15 thread for my 8-year odyssey to find high-performance 15-inch tires.
In your favored size, I think you are limited to:
1. BF Goodrich Radial T/A
Doesn't look too high performance to me, but maybe it has advanced under the skin?
2. Hoosier Speedster
Great performance once hot, I am told—but the Hoosier people are very against seeing the tire on a street car.
3. Yokohama A048
I hear good things, but treadwear is rated at 60 and they're $216/ea. Then again, they may be a better pick than the Hoosiers.
4. An uninspiring selection of Camry-oriented all-season and touring tires.
I just couldn't go there, even if they're better than period 914 tires. Find some of 'em here:
http://www.tirerack.com/tires/TireSearchRe...7&zip-code=I eventually toyed with 195/65R15 and 215/60R15 Pirelli P6000s, as they were the only summer tires I could find in a size near 205/60. But the 215s wouldn't fit in the rear of my narrow body without fender mods, and by the time I was going to 195s, I decided to try 185/70 Avon vintage race/rally tires. Maybe someone else has a hot ticket I missed, or is new to market?
