When I had my 87 gt, fairly stock with a brand new motor, a couple of bolt on's and 4.30 gears, I bought a full set of kelly tires. They were all 205/65/R15 front and back. (Didn't look that great with that small of tire out back.) They hooked pretty good. Enough to get me mid 2.0 60's all night long and a best of 2.02. Its very rare you see a street tire run 1.90's, and thats usually a very wide tire. So yes they are pretty good.
